                                   LETTERHEAD
 
                                                                   July 31, 1996
 
Dear Stockholder:
 
    It  is my pleasure to invite you to attend a Special Meeting of Stockholders
(the "Special Meeting") of Financial  Security Corp. ("Financial Security"),  to
be  held at Financial Security's offices located at 1209 North Milwaukee Avenue,
Chicago, Illinois on September 11, 1996 at 3:00 p.m., Chicago time.
 
    The purpose of this meeting is to  consider and vote upon the Agreement  and
Plan  of Merger, dated as  of April 22, 1996,  between Pinnacle Banc Group, Inc.
("Pinnacle") and Financial Security (the "Merger Agreement"), pursuant to which,
among other things,  Financial Security will  be merged with  and into  Pinnacle
(the "Merger"). Pinnacle is the holding company for Pinnacle Bank, Pinnacle Bank
of  the Quad-Cities and Pinnacle  Bank F.S.B. A copy  of the Merger Agreement is
attached to the accompanying Joint Proxy Statement/Prospectus.
 
    The following  items relating  to the  Special Meeting  and the  Merger  are
enclosed:
 
    1.  Joint Proxy Statement/Prospectus;
 
    2.  Proxy Card (White);
 
    3.  Election Form (Blue) as described below;
 
    4.    A white  postage-paid return  envelope addressed  to Harris  Trust and
       Savings Bank for the Proxy Card; and
 
    5.   A blue  postage-paid  return envelope  addressed  to Harris  Trust  and
       Savings Bank for the Election Form.
 
    At  the effective  time of the  Merger, each outstanding  share of Financial
Security Common Stock will be converted into and represent the right to  receive
either (i) .8803 shares (the "Exchange Ratio") of Pinnacle Common Stock, subject
to  adjustment as  described in the  enclosed Joint  Proxy Statement/ Prospectus
(the "Stock  Distribution");  (ii)  $28.50 in  cash  (the  "Cash  Distribution")
(provided that the number of shares of Financial Security Common Stock for which
stockholders elect to receive cash will not exceed 45% of the outstanding shares
of  Financial Security Common Stock); or (iii) an amount in cash equal to 30% of
the Cash Distribution and shares  of Pinnacle Common Stock  equal to 70% of  the
Stock  Distribution (the  "Combined Distribution"  and together  with the "Stock
Distribution" and the "Cash Distribution," the "Merger Consideration").
 
    YOU WILL  HAVE  THE  OPPORTUNITY  TO ELECT  WHETHER  TO  RECEIVE  THE  STOCK
DISTRIBUTION,  THE CASH DISTRIBUTION OR THE COMBINED DISTRIBUTION. ENCLOSED WITH
THIS JOINT PROXY STATEMENT/PROSPECTUS IS AN ELECTION FORM (THE "ELECTION  FORM")
WHEREBY  YOU MAY INDICATE YOUR ELECTION. IN ORDER FOR AN ELECTION FORM (BLUE) TO
BE DEEMED EFFECTIVE, SUCH ELECTION FORM MUST BE PROPERLY COMPLETED, EXECUTED AND
RETURNED TO HARRIS  TRUST AND SAVINGS  BANK, THE EXCHANGE  AGENT, BY 5:00  P.M.,
CHICAGO  TIME  ON SEPTEMBER  10,  1996. OTHERWISE,  YOU  WILL RECEIVE  THE STOCK
DISTRIBUTION.
 
    Depending on the number of Financial Security stockholders choosing the Cash
Distribution, Financial  Security stockholders  who elect  to receive  the  Cash
Distribution  may receive  a combination  of cash  and Pinnacle  Common Stock in
order to preserve the favorable tax treatment of the Merger.
 
    The consideration received in connection with the Stock Distribution and the
Combined Distribution  is  subject  to  possible  adjustment  depending  on  the
Pinnacle  Average Stock Price (as defined in  the Merger Agreement) prior to the
Effective  Time,  and  as  discussed  in  greater  detail  in  the  Joint  Proxy
Statement/Prospectus.  Because the  market value  of Pinnacle  Common Stock will
fluctuate, the market  value of  Pinnacle Common Stock  that Financial  Security
stockholders may receive upon actual consummation of the Merger will increase or
decrease  prior to, as well  as after, the consummation  of the Merger. The Cash
Distribution is not subject  to any possible adjustment  in connection with  the
Pinnacle Average Stock Price.
<PAGE>
    Pinnacle Common Stock trades on the Nasdaq Small Cap Market under the symbol
"PINN."  The per share closing price of  Pinnacle Common Stock on July 26, 1996,
the latest  practicable trading  date before  the printing  of the  Joint  Proxy
Statement/Prospectus was $30.00. There can be no assurance what the market value
of  Pinnacle  Common  Stock  will  be  at  the  Effective  Time.  Depending upon
fluctuations in the price of Pinnacle Common Stock during the measurement period
for the determination of the Pinnacle  Average Stock Price, the market value  of
Pinnacle Common Stock may be more or less than $30.00. You are advised to obtain
a current market quotation for the shares of Pinnacle Common Stock.
 
    As  described in the  Joint Proxy Statement/Prospectus,  consummation of the
Merger is subject  to certain  conditions including  approval of  the Merger  by
various  regulatory agencies. In addition, the  approval of the Merger Agreement
by the holders  of a majority  of the outstanding  shares of Financial  Security
Common  Stock and the holders of two-thirds of the issued and outstanding shares
of Pinnacle Common Stock is required.
 
    THE FINANCIAL SECURITY BOARD OF DIRECTORS BELIEVES THAT THE MERGER IS IN THE
BEST INTERESTS OF FINANCIAL  SECURITY AND ITS  STOCKHOLDERS AND RECOMMENDS  THAT
YOU  VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT. The proposed Merger
has been approved by the Financial Security Board as being in the best  interest
of  Financial Security  and its  stockholders. The  Board reached  this decision
after careful  consideration  of a  number  of factors,  including  the  written
opinion  of Hovde  Financial, Inc. ("Hovde"),  its financial adviser,  as of the
date of the execution of the Merger Agreement, that the Merger Consideration  is
fair  from  a financial  point  of view  to  Financial Security  stockholders. A
written  opinion,  dated   as  of  the   date  of  the   enclosed  Joint   Proxy
Statement/Prospectus,  of  Hovde is  reproduced in  full in  Appendix II  to the
accompanying Joint Proxy Statement/Prospectus.
 
    The enclosed Joint Proxy Statement/Prospectus  explains in detail the  terms
of  the Merger, as well as other  information relating to Pinnacle and Financial
Security. Please carefully review and consider all of this information.
 
    YOUR PARTICIPATION  IN  THE SPECIAL  MEETING,  IN  PERSON OR  BY  PROXY,  IS
ESPECIALLY IMPORTANT. AN ABSTENTION OR FAILURE TO VOTE AT THE SPECIAL MEETING OR
FAILURE  TO SUBMIT  A PROXY WILL  HAVE THE SAME  EFFECT AS A  VOTE "AGAINST" THE
MERGER. ACCORDINGLY, PLEASE SIGN, DATE AND  MAIL THE ENCLOSED PROXY PROMPTLY  IN
THE POSTAGE-PAID ENVELOPE THAT HAS BEEN PROVIDED TO YOU FOR YOUR CONVENIENCE. IF
YOU ATTEND THE SPECIAL MEETING, YOU MAY VOTE IN PERSON, IF YOU WISH, EVEN IF YOU
HAVE  PREVIOUSLY  RETURNED  YOUR  PROXY  CARD (WHITE).  HOWEVER,  IF  YOU  ARE A
STOCKHOLDER WHOSE SHARES  ARE NOT  REGISTERED IN YOUR  OWN NAME,  YOU WILL  NEED
ADDITIONAL  DOCUMENTATION  FROM  YOUR  RECORDHOLDER TO  VOTE  PERSONALLY  AT THE
SPECIAL MEETING.
 
    Thank you for your attention to this important matter.
 
                                          Sincerely yours,
 
                                          /s/ Daniel K. Augustine
                                          Daniel K. Augustine
                                          President and Chief Executive Officer.
 
    FINANCIAL  SECURITY  STOCKHOLDERS  SHOULD  NOT  FORWARD  STOCK  CERTIFICATES
REPRESENTING SHARES OF FINANCIAL SECURITY COMMON STOCK AT THIS TIME. A LETTER OF
TRANSMITTAL   SETTING  FORTH  INSTRUCTIONS  REGARDING   THE  SURRENDER  OF  SUCH
CERTIFICATES AND THE  ISSUANCE OF CERTIFICATES  REPRESENTING SHARES OF  PINNACLE
COMMON STOCK WILL BE FURNISHED TO FINANCIAL SECURITY STOCKHOLDERS PROMPTLY AFTER
THE EFFECTIVE TIME OF THE MERGER.

among other things,  Financial Security will  be merged with  and into  Pinnacle
(the  "Merger") and Pinnacle  will issue shares of  its authorized common stock,
par value $4.69 per share ("Pinnacle Common Stock"), to holders of common  stock
of  Financial  Security (other  than Pinnacle  or any  of its  subsidiaries) and
holders of Financial  Security stock options  that are exchanged  for shares  of
Pinnacle  Common Stock. Financial  Security is the  holding company for Security
Federal Savings and Loan Association of Chicago.
 
    At the effective  time of the  Merger, each outstanding  share of  Financial
Security  Common  Stock  (other than  shares  held  by Pinnacle  or  any  of its
subsidiaries) will be converted into and represent the right to receive (upon  a
Financial   Security  stockholder's  election)  either  (i)  .8803  shares  (the
"Exchange Ratio") of Pinnacle Common  Stock, subject to adjustment as  described
in  the enclosed  Joint Proxy  Statement/Prospectus (the  "Stock Distribution");
(ii) $28.50  in cash  (the "Cash  Distribution") (provided  that the  number  of
shares  of  Financial  Security Common  Stock  for which  stockholders  elect to
receive cash will not exceed 45% of the outstanding shares of Financial Security
Common Stock); or (iii) an amount in cash equal to 30% of the Cash  Distribution
and  shares of Pinnacle Common Stock equal to 70% of the Stock Distribution (the
"Combined Distribution" and together with the "Stock Distribution" and the "Cash
Distribution," the "Merger Consideration").
 
    Pursuant to Section 11.20 of the Illinois Business Corporation Act of  1983,
as  amended (the "IBCA"), Pinnacle stockholders would not be entitled to vote on
the proposal to approve and adopt the Merger Agreement if the shares of Pinnacle
Common Stock to be issued  in connection with the  Merger did not exceed  twenty
percent  (20%) of  the shares of  Pinnacle Common  Stock outstanding immediately
prior to the  Effective Time.  While Pinnacle  Common Stock  must constitute  at
least  fifty-five  percent  (55%)  of  the  aggregate  consideration  payable by
Pinnacle in connection with  the Merger, it  is not certain  how many shares  of
Pinnacle  Common Stock will be issued in  connection with the Merger and whether
such shares will exceed  twenty percent (20%) of  the shares of Pinnacle  Common
Stock outstanding immediately prior to the Effective Time. As a result, Pinnacle
has  scheduled the Pinnacle  Meeting to approve and  adopt the Merger Agreement.
Approval of the Merger  by holders of two-thirds  of the issued and  outstanding
shares   of  Pinnacle  Common  Stock  is  a  condition  to,  and  required  for,
consummation of the Merger. The Merger also requires regulatory approval and the
approval of the Merger Agreement by the holders of a majority of the outstanding
shares of  Financial Security  Common Stock.  On September  11, 1996,  Financial
Security  stockholders will  consider the  approval and  adoption of  the Merger
Agreement.
 
    THE PINNACLE BOARD  OF DIRECTORS  BELIEVES THAT THE  MERGER IS  IN THE  BEST
INTERESTS  OF PINNACLE  AND ITS  STOCKHOLDERS AND  RECOMMENDS THAT  YOU VOTE FOR
APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.
 
    The enclosed Joint Proxy Statement/Prospectus  explains in detail the  terms
of  the Merger, as well as other  information relating to Pinnacle and Financial
Security. Please carefully review and consider all of this information.
 
    YOUR PARTICIPATION  IN  THE SPECIAL  MEETING,  IN  PERSON OR  BY  PROXY,  IS

                                 PROSPECTUS OF
                           PINNACLE BANC GROUP, INC.
                                UP TO 1,456,362
               SHARES OF COMMON STOCK (PAR VALUE $4.69 PER SHARE)
                            ------------------------
 
    This  Joint Proxy Statement/Prospectus  relates to the  proposed merger (the
"Merger") of  Financial  Security  Corp.,  a  Delaware  corporation  ("Financial
Security"),  with and  into Pinnacle Banc  Group, Inc.,  an Illinois corporation
("Pinnacle"), with  Pinnacle as  the  surviving corporation  in the  Merger,  as
contemplated by the Agreement and Plan of Merger (the "Merger Agreement"), dated
as  of April 22,  1996, between Pinnacle  and Financial Security.  A copy of the
Merger Agreement is included as Appendix I hereto and incorporated by  reference
herein.
 
    This Joint Proxy Statement/Prospectus is being furnished to the stockholders
of  Pinnacle  and  Financial Security  in  connection with  the  solicitation of
proxies by the respective Boards of Directors of Pinnacle and Financial Security
for use  at the  special  meetings of  stockholders  of Pinnacle  and  Financial
Security,  each  to be  held  on September  11,  1996, including  any respective
adjournments or  postponements  of  such  meetings.  At  such  meetings  or  any
adjournments   or  postponements  thereof,  the  stockholders  of  Pinnacle  and
Financial Security will be asked to consider  and vote on a proposal to  approve
and  adopt the Merger Agreement pursuant to which, among other things, Financial
Security will be merged with and into Pinnacle.
 
    This Joint  Proxy  Statement/Prospectus  also constitutes  a  prospectus  of
Pinnacle  with respect to  the shares of  its common stock,  par value $4.69 per
share ("Pinnacle  Common Stock")  to be  issued to  holders of  common stock  of
Financial Security, par value $.01 per share ("Financial Security Common Stock")
and  to holders of  outstanding stock options of  Financial Security who receive
shares of Pinnacle Common Stock in consideration therefor pursuant to the  terms
of the Merger Agreement.
 
    Subject  to the  terms, conditions  and procedures  set forth  in the Merger
Agreement, each share of Financial Security Common Stock outstanding immediately
prior to the  consummation of the  Merger will  be converted into  the right  to
receive either (i) .8803 shares (the "Exchange Ratio") of Pinnacle Common Stock,
subject  to  adjustment as  described  herein (the  "Stock  Distribution"); (ii)
$28.50 in cash (the "Cash Distribution") (provided that the number of shares  of
Financial  Security Common Stock subject to an election to receive cash will not
exceed 45% of  the outstanding shares  of Financial Security  Common Stock);  or
(iii)  an amount  in cash equal  to 30% of  the Cash Distribution  and shares of
Pinnacle Common Stock  equal to  70% of  the Stock  Distribution (the  "Combined
Distribution"   and  together  with  the  "Stock  Distribution"  and  the  "Cash
Distribution," the "Merger Consideration"). Pursuant to the terms of the  Merger
Agreement,  cash will be  paid in lieu  of fractional shares  of Pinnacle Common
Stock. For a more complete description of the Merger Agreement and the terms  of
the Merger, see "THE MERGER."
 
    Each  Financial  Security stockholder  will  have the  opportunity  to elect
whether to receive either the Stock  Distribution (a "Stock Election," in  which
case,  such holder's shares shall be deemed  to be "Stock Election Shares"), the
Cash Distribution (a "Cash Election," in which case, such holder's shares  shall
be deemed to be "Cash Election Shares"), or a Combined Distribution (a "Combined
Election,"  in which case, such holder's shares  shall be deemed to be "Combined
Election Shares"). ENCLOSED  WITH THIS  JOINT PROXY  STATEMENT/PROSPECTUS IS  AN
ELECTION  FORM FOR USE BY THE  STOCKHOLDERS OF FINANCIAL SECURITY (THE "ELECTION
FORM") WHEREBY  STOCKHOLDERS MAY  INDICATE A  STOCK ELECTION,  CASH ELECTION  OR
COMBINED  ELECTION. IN ORDER FOR AN ELECTION  FORM TO BE DEEMED TO BE EFFECTIVE,
SUCH ELECTION FORM MUST BE PROPERLY COMPLETED AND DULY EXECUTED BY THE FINANCIAL
SECURITY STOCKHOLDER  AND  RETURNED  TO  HARRIS  TRUST  AND  SAVINGS  BANK  (THE
"EXCHANGE  AGENT") BY 5:00 P.M.,  CHICAGO TIME, ON THE DAY  PRIOR TO THE DATE OF
THE SPECIAL MEETING OF FINANCIAL SECURITY  OR SEPTEMBER 10, 1996 (THE  "ELECTION
DEADLINE").  IF  A  COMPLETED ELECTION  FORM  IS  NOT RECEIVED  BY  THE ELECTION
DEADLINE, A FINANCIAL SECURITY STOCKHOLDER SHALL RECEIVE THE STOCK DISTRIBUTION.
SEE "THE MERGER -- ELECTION PROCEDURES".
 
    The Exchange Ratio is equal to the quotient of the agreed value of Financial
Security Common  Stock per  share, $28.50,  divided by  the per  share value  of
Pinnacle  Common Stock during a ten day trading period prior to the execution of
the Merger Agreement, $32.375.
 
    Pursuant to the Merger  Agreement, if the Pinnacle  Average Stock Price  (as
defined  below) is less than $30.00 per share but greater than $27.99 per share,
the Exchange Ratio  shall be adjusted  to equal the  quotient of $26.00  divided
 
                                                        (CONTINUED ON NEXT PAGE)
<PAGE>
by  the Pinnacle  Average Stock  Price. However,  if the  Pinnacle Average Stock
Price is greater than $35.00 per share but does not exceed $37.00 per share, the
Exchange Ratio shall be adjusted to equal the quotient of $31.00 divided by  the
Pinnacle Average Stock Price. The Pinnacle Average Stock Price is defined as the
average of the closing prices per share of Pinnacle Common Stock reported by the
Nasdaq  Small Cap Market (the "Nasdaq SCM") on the ten trading days on which one
or more  trades actually  occur immediately  prior to  the second  business  day
preceding the consummation of the Merger (the "Closing Date").
 
    However,  if the Pinnacle Average Stock Price is less than $28.00 per share,
the Exchange Ratio  shall be further  adjusted to .9286  and Financial  Security
shall  have the option to  terminate the Merger Agreement  unless not later than
two days  prior to  the Closing  Date,  Pinnacle agrees  to further  adjust  the
Exchange  Ratio to equal the quotient of  $26.00 divided by the Pinnacle Average
Stock Price. Conversely, if the Pinnacle Average Stock Price exceeds $37.00  per
share,  the Exchange Ratio shall be further adjusted to .8378 and Pinnacle shall
have the option to terminate the Merger Agreement unless not later than two days
prior to  the Closing  Date, Financial  Security agrees  to further  adjust  the
Exchange  Ratio to equal the quotient of  $31.00 divided by the Pinnacle Average
Stock Price.
 
    The market price of Pinnacle  Common Stock to be  received in the Merger  is
subject  to  fluctuation  and such  fluctuation  may  result in  an  increase or
decrease in the value of the Stock Distribution or the Combined Distribution  to
be received by Financial Security stockholders in the Merger. See "THE MERGER --
Merger Consideration".
 
    Neither Financial Security nor Pinnacle is required to exercise its right to
terminate  the Merger  Agreement based  on the  market value  of Pinnacle Common
Stock at the Effective  Time. No decision  can be made unless  and until it  can
reasonably be anticipated that the Pinnacle Average Stock Price will trigger the
termination  rights whereupon  the appropriate  board of  directors will  make a
determination based on the relevant circumstances existing at that time.
 
    The  Cash  Distribution  is  not  subject  to  any  possible  adjustment  in
connection with the Pinnacle Average Stock Price.
 
    The  outstanding  shares of  Pinnacle  Common Stock  and  Financial Security
Common Stock are listed on  the Nasdaq SCM and  the Nasdaq National Market  (the
"Nasdaq  National Market"),  respectively under  the symbols  "PINN" and "FNSC",
respectively. The per share closing price of Pinnacle Common Stock and Financial
Security Common  Stock  on  the  Nasdaq SCM  and  the  Nasdaq  National  Market,
respectively  on July 26,  1996, the latest practicable  trading date before the
printing of  this  Joint Proxy  Statement/Prospectus,  was $30.00  and  $25.875,
respectively.  Financial  Security stockholders  are  advised to  obtain current
market quotations for Pinnacle Common Stock.
 
    Consummation of the  Merger is  subject to the  approval of  the holders  of
two-thirds  of the issued and outstanding shares  of Pinnacle Common Stock and a
majority of the issued and outstanding shares of Financial Security Common Stock
and the receipt  of required  regulatory approvals  as well  as other  customary
conditions.

STOCKHOLDER OF FINANCIAL SECURITY, SEE "RISK FACTORS".

                                  THE MEETINGS
 
PINNACLE MEETING
 
    MEETING DATE.  The Pinnacle Meeting of Stockholders (the "Pinnacle Meeting")
will be held at 2215 York Road, Oak Brook, Illinois 60521 on September 11, 1996,
at 10:00 a.m., Chicago time, and at the place, date and time designated for  any
and  all adjournments  or postponements thereof.  See "THE  MEETINGS -- Pinnacle
Meeting."
 
    RECORD DATE.  Only holders of record  of shares of Pinnacle Common Stock  at
the close of business on July 26, 1996 (the "Pinnacle Record Date") are entitled
to  notice of and to vote at the Pinnacle Meeting. See "THE MEETINGS -- Pinnacle
Meeting."
 
    MATTERS TO BE  CONSIDERED.  At  the Pinnacle Meeting,  holders of shares  of
Pinnacle Common Stock will consider and vote on the approval and adoption of the
Merger  Agreement  and  the  transactions  contemplated  thereby,  including the
Merger, and pursuant  to which  Pinnacle will  issue shares  of Pinnacle  Common
Stock  to holders of Financial Security Common Stock (other than Pinnacle or any
of its subsidiaries) electing to receive Pinnacle Common Stock in  consideration
therefor  and holders of Financial Security  stock options who receive shares of
Pinnacle Common Stock  in consideration of  said options. See  "THE MEETINGS  --
Pinnacle   Meeting."  Pursuant  to  Section   11.20  of  the  Illinois  Business
Corporation Act of 1983,  as amended (the  "IBCA"), Pinnacle stockholders  would
not  be  entitled  to vote  on  the proposal  to  approve and  adopt  the Merger
Agreement if the shares of Pinnacle Common Stock to be issued in connection with
the Merger did not exceed twenty percent (20%) of the shares of Pinnacle  Common
Stock outstanding immediately prior to the Effective Time. While Pinnacle Common
Stock  must constitute fifty-five  percent (55%) of  the aggregate consideration
payable by Pinnacle in connection  with the Merger, it  is not certain how  many
shares of Pinnacle Common Stock will be issued in connection with the Merger and
whether  such shares will exceed twenty percent  (20%) of the shares of Pinnacle
Common Stock outstanding immediately prior to  the Effective Time. As a  result,
Pinnacle  has scheduled  the Pinnacle  Meeting to  approve and  adopt the Merger
Agreement. Approval of the  Merger by the Pinnacle  stockholders is a  condition
to,  and required for, consummation of the Merger. See "THE MEETINGS -- Pinnacle
Meeting."
 
    VOTE REQUIRED.   The affirmative vote  of the holders  of two-thirds of  the
issued  and outstanding shares of Pinnacle Common Stock is required for approval
and adoption of the Merger Agreement. Therefor, abstentions and broker non-votes
will have the  same effect as  votes against  the approval and  adoption of  the
Merger Agreement. As of the Pinnacle Record Date, there were 4,302,716 shares of
 
                                       9
<PAGE>
Pinnacle  Common Stock  entitled to  be voted  at the  Pinnacle Meeting.  With a
quorum, or in the  absence of such,  the affirmative vote of  a majority of  the
shares  represented at the Pinnacle Meeting may authorize the adjournment of the
meeting. See "THE MEETINGS -- Pinnacle Meeting."
 
    SECURITY OWNERSHIP.  As of the Pinnacle Record Date, directors and executive
officers of Pinnacle held  in the aggregate  2,192,632 shares (excluding  option
shares),  or approximately 50.96%  of the then issued  and outstanding shares of
Pinnacle Common Stock.  The directors  and executive officers  of Pinnacle  have
indicated  that they  intend to  vote such shares  of Pinnacle  Common Stock for
approval and  adoption  of the  Merger  at the  Pinnacle  Meeting.  Accordingly,
holders  of an  additional 15.71% of  the outstanding shares  of Pinnacle Common
Stock entitled to vote must vote such shares in favor of the Merger in order for
such proposals to be  approved. As of May  31, 1996, neither Financial  Security
and its subsidiaries, nor, to the knowledge of Financial Security, the directors
and  executive officers  of Financial  Security and  their affiliates,  held any
outstanding shares  of Pinnacle  Common  Stock. See  "THE MEETINGS  --  Pinnacle
Meeting."
 
    Pursuant  to the  Merger Agreement, affiliates  of Pinnacle  or the Pinnacle
Subsidiary Banks, including officers, employees, directors or holders of greater
than ten percent of the outstanding shares of Pinnacle Common Stock have  agreed
not  to purchase any Pinnacle Common Stock during the thirty business days prior
to the consummation of the Merger.

vote must vote such shares  in favor of the Merger  Agreement in order for  such
proposal  to  be approved.  As of  the Financial  Security Record  Date, neither

                                   THE MERGER
 
    THE  FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL
TEXT OF  THE  MERGER AGREEMENT,  WHICH  IS ATTACHED  HERETO  AS APPENDIX  I  AND
INCORPORATED BY REFERENCE HEREIN.
 
GENERAL
 
    The  stockholders of Pinnacle and Financial Security are each being asked to
separately consider and  vote upon a  proposal to approve  and adopt the  Merger
Agreement,  pursuant to  which Financial Security  will be merged  with and into
Pinnacle, with Pinnacle being the surviving corporation in the Merger. The  name
of the surviving corporation in the Merger will be "Pinnacle Banc Group, Inc."
 
MERGER CONSIDERATION
 
    At  the  effective  time of  the  Merger (the  "Effective  Time"), Financial
Security will  merge  with and  into  Pinnacle  in accordance  with  the  Merger
Agreement  whereby  the separate  existence  of Financial  Security  will cease.
Subject to  the  terms,  conditions  and procedures  set  forth  in  the  Merger
Agreement, each share of Financial Security Common Stock outstanding immediately
prior to the consummation of the Merger will be converted into and represent the
right  to receive (upon a Financial  Security stockholder's election) either (i)
 .8803 shares  (the  "Exchange  Ratio")  of Pinnacle  Common  Stock,  subject  to
adjustment  as described below  (the "Stock Distribution");  (ii) $28.50 in cash
(the "Cash  Distribution") (provided  that  the number  of shares  of  Financial
Security Common Stock subject to an election to receive cash will not exceed 45%
of  the  outstanding shares  of Financial  Security Common  Stock); or  (iii) an
amount in cash  equal to 30%  of the  Cash Distribution and  shares of  Pinnacle
Common Stock equal to 70% of the Stock Distribution (the "Combined Distribution"
and  together with  the "Stock  Distribution" and  the "Cash  Distribution," the
"Merger Consideration"). Pursuant  to the  terms of the  Merger Agreement,  cash
will be paid in lieu of fractional shares of Pinnacle Common Stock.
 
    The Exchange Ratio is equal to the quotient of the agreed value of Financial
Security  Common Stock  per share,  $28.50, divided  by the  per share  value of
Pinnacle Common Stock during a ten day trading period prior to the execution  of
the Merger Agreement, $32.375.
 
    Pursuant  to the Merger  Agreement, if the Pinnacle  Average Stock Price (as
defined below) is less than $30.00 per share but greater than $27.99 per  share,
the  Exchange Ratio shall be adjusted to equal the quotient of $26.00 divided by
the Pinnacle Average Stock Price. However,  if the Pinnacle Average Stock  Price
is  greater than  $35.00 per  share but  does not  exceed $37.00  per share, the
Exchange Ratio shall be adjusted to equal the quotient of $31.00 divided by  the
Pinnacle Average Stock Price. The Pinnacle Average Stock Price is defined as the
average of the closing prices per share of Pinnacle Common Stock reported by the
Nasdaq  Small Cap Market (the "Nasdaq SCM") on the ten trading days on which one
or more  trades actually  occur immediately  prior to  the second  business  day
preceding the Closing Date.
 
    However,  if the Pinnacle Average Stock Price is less than $28.00 per share,
the Exchange Ratio  shall be further  adjusted to .9286  and Financial  Security
shall  have the option to  terminate the Merger Agreement  unless not later than
two days  prior to  the Closing  Date,  Pinnacle agrees  to further  adjust  the
Exchange  Ratio to equal the quotient of  $26.00 divided by the Pinnacle Average
Stock Price. Conversely, if the Pinnacle Average Stock Price exceeds $37.00  per
share,  the Exchange Ratio shall be further adjusted to .8378 and Pinnacle shall
have the option to terminate the Merger Agreement unless not later than two days
prior to  the Closing  Date, Financial  Security agrees  to further  adjust  the
Exchange  Ratio to equal the quotient of  $31.00 divided by the Pinnacle Average
Stock Price.
 
    The market price of Pinnacle  Common Stock to be  received in the Merger  is
subject  to  fluctuation  and such  fluctuation  may  result in  an  increase or
decrease in the value of the Stock Distribution or the Combined Distribution  to
be received by Financial Security stockholders in the Merger.
 
    Neither Financial Security nor Pinnacle is required to exercise its right to
terminate  the Merger  Agreement based  on the  market value  of Pinnacle Common
Stock at the Effective Time. No decision
 
                                       11
<PAGE>
can be made unless and until it can reasonably be anticipated that the  Pinnacle
Average   Stock  Price  will  trigger   the  termination  rights  whereupon  the
appropriate board of directors will make  a determination based on the  relevant
circumstances  existing at that time. You are advised to obtain a current market
quotation for the shares of Pinnacle Common Stock. See "COMPARATIVE STOCK PRICES
AND DIVIDEND INFORMATION."
 
    The  Cash  Distribution  is  not  subject  to  any  possible  adjustment  in
connection  with the  Pinnacle Average  Stock Price.  See "THE  MERGER -- Merger
Consideration" and "-- Election Procedures".
 
    In addition, the Merger Consideration may be adjusted pursuant to changes in
the value of the Bennett Portfolio as discussed under "THE MERGER -- Termination
and Termination Fee" and "BUSINESS OF FINANCIAL SECURITY -- Loan Portfolio."
 
    In addition, each  option to  purchase shares of  Financial Security  Common
Stock  shall be converted  at the Effective  Time into such  number of shares of
Pinnacle Common Stock as are equal in value to (i) the product of (A) the number
of shares of Financial Security Common Stock subject to Financial Security stock
options; (B) the Exchange Ratio; and (C) the Pinnacle Average Stock Price;  less
(ii) the aggregate exercise price for the number of shares of Financial Security
Common Stock subject to the options.
 
RECOMMENDATION OF THE BOARDS OF DIRECTORS
 
    The   Board  of  Directors  of  each  of  Pinnacle  and  Financial  Security
unanimously recommends that the stockholders of their respective companies  vote
FOR  approval of the Merger Agreement. The  Boards of Directors of both Pinnacle
and Financial Security, after consideration of  the terms and conditions of  the
Merger  Agreement and other  factors deemed relevant, believe  that the terms of
the Merger Agreement are fair to, and in the best interests of, Pinnacle and its
stockholders and Financial Security and its stockholders, respectively. See "THE
MERGER --  Background  of the  Merger,"  "-- Reasons  for  the Merger"  and  "--
Recommendations of the Boards of Directors."
 
OPINION OF FINANCIAL ADVISOR
 
    Financial  Security has  received the opinion  of Hovde  Financial, Inc., an
investment banking firm ("Hovde"), that the Merger Consideration to be  received
by  the holders of Financial Security Common  Stock pursuant to the terms of the
Merger is fair to the Financial Security stockholders from a financial point  of
view.  Hovde's opinion is directed  only to the consideration  to be received by
the holders  of  Financial Security  Common  Stock  and does  not  constitute  a
recommendation  to any holders of Financial Security Common Stock as to how such
holders of Financial Security Common Stock should vote at the Financial Security
Meeting or as to any other  matter. For additional information concerning  Hovde
and  its opinion, see "THE MERGER --  Opinion of Financial Advisor". The opinion
of  such   firm   is   attached   as   Appendix   II   to   this   Joint   Proxy
Statement/Prospectus.
 
ELECTION PROCEDURES
 
    Each  Financial Security  stockholder will  have the  opportunity to  make a
Stock Election, a  Cash Election,  or a  Combined Election.  ENCLOSED WITH  THIS
JOINT   PROXY  STATEMENT/PROSPECTUS  IS  THE  ELECTION   FORM  FOR  USE  BY  THE
STOCKHOLDERS OF FINANCIAL  SECURITY WHEREBY  STOCKHOLDERS MAY  INDICATE A  STOCK
ELECTION,  CASH ELECTION OR COMBINED ELECTION. IN  ORDER FOR AN ELECTION FORM TO
BE DEEMED TO  BE EFFECTIVE, SUCH  ELECTION FORM MUST  BE PROPERLY COMPLETED  AND
DULY  EXECUTED BY  THE FINANCIAL  SECURITY STOCKHOLDERS  AND RETURNED  TO HARRIS
TRUST AND SAVINGS BANK (THE "EXCHANGE AGENT") BY 5:00 P.M., CHICAGO TIME, ON THE
DAY PRIOR TO THE DATE  OF THE FINANCIAL SECURITY  MEETING OR SEPTEMBER 10,  1996
(THE "ELECTION DEADLINE").
 
    Each  separate entry on  Financial Security's list  of stockholders shall be
presumed to represent  a separate  and distinct  holder of  record of  Financial
Security  Common Stock. Shares held of record  by a bank, trust company, broker,
dealer or other recognized nominee shall be deemed to be held by a single holder
unless the nominee  advises the Exchange  Agent otherwise, in  which case,  each
beneficial  owner will be treated  as a separate holder  and, either directly or
through such nominee, may submit a  separate Election Form. Any election may  be
revoked or changed by the person submitting an Election
 
                                       12
<PAGE>
Form or any other person to whom the subject shares are subsequently transferred
by  submission  of  a later  dated  Election  Form properly  completed  and duly
executed, received by the Exchange Agent by the Election Deadline.
 
    Any stockholder who fails to deliver a properly completed and duly  executed
Election  Form to the Exchange Agent by the Election Deadline shall be deemed to
have made no  election (a  "No Election," in  which case,  such holder's  shares
shall  be deemed to be "No Election Shares"). No Election Shares will be treated
as Stock Election Shares for purposes of determining the type and amount of  the
Merger Consideration payable pursuant to the Merger.
 
    In  the event the number of shares of Pinnacle Common Stock distributable in
respect of the Stock  Election Shares and the  Combined Election Shares is  less
than fifty-five percent (55%) of the Merger Consideration or such greater amount
as  required by the Minimum Share Notice  (as defined below), the Exchange Agent
will reallocate the  Merger Consideration  payable to  each holder  of the  Cash
Election Shares pro rata (based upon the number of Cash Election Shares owned by
such  holder as compared with the total  number of Cash Election Shares owned by
all holders) such that holders of  Cash Election Shares will receive the  number
of  shares of Pinnacle Common Stock which in the aggregate will equal fifty-five
percent (55%) of the Merger Consideration or the amount set forth in the Minimum
Share Notice. The balance of the Merger  Consideration, if any, will be paid  in
cash.  The Minimum  Share Notice  is the  notice that  the law  firm of Muldoon,
Murphy & Faucette, counsel to Financial Security ("Muldoon"), will issue to  the
Exchange  Agent if the total number of  shares of Pinnacle Common Stock issuable
to all holders  of the  Stock Election Shares  and Combined  Election Shares  is
insufficient  to  allow Muldoon  to issue  its opinion  concerning the  tax free
nature of the Merger.
 
    Following consummation of the Merger, the Exchange Agent will distribute the
applicable Merger Consideration  in exchange  for shares  of Financial  Security
Common  Stock.  See "THE  MERGER --  Election Procedures"  and "--  Surrender of
Certificates".
 
CLOSING DATE
 
    The Closing Date  of the  Merger will be  within thirty  (30) business  days
after  (i) the expiration  of all applicable waiting  periods in connection with
approvals  of  governmental   authorities  and  (ii)   all  conditions  to   the
consummation  of the Merger have been satisfied or waived in accordance with the
terms of  the Merger  Agreement, or  at another  time agreed  to in  writing  by
Pinnacle  and Financial Security. Subject  to obtaining all requisite approvals,
Pinnacle and Financial  Security currently  anticipate that the  Merger will  be
consummated  in September, 1996.  See "THE MERGER --  Effective Time and Closing
Date".
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
    Pursuant to the terms of the Merger Agreement, Financial Security has agreed
that until  the Effective  Time, it  will  conduct its  business in  the  usual,
regular  and ordinary course  consistent with past  practice and prudent banking
practice and use its best efforts  to maintain and preserve intact its  business
organization,   properties,   leases,   employees   and   advantageous  business
relationships and  retain  the appropriate  services  of its  officers  and  key
employees.  In addition, Financial Security has  agreed to consult with Pinnacle
prior to taking certain action as well as not to pay cash dividends on shares of
Financial Security Common  Stock prior to  October 22, 1996,  without the  prior
approval  of Pinnacle. Pinnacle has agreed that until the Effective Time, it and
the Pinnacle Subsidiary Banks will carry  on their respective businesses in  the
usual,  regular and  ordinary course consistent  with past  practice and prudent
banking practice. See "THE MERGER --  Conduct of Business of Financial  Security
Pending the Merger"; " -- Conduct of Business of Pinnacle Pending the Merger."
 
CONDITIONS TO THE CONSUMMATION OF THE MERGER AND REGULATORY APPROVALS
 
    Consummation  of  the  Merger is  subject  to  satisfaction of  a  number of
conditions, including approval of  the Merger Agreement  by the stockholders  of
Pinnacle and Financial Security, the receipt
 
                                       13
<PAGE>
of all regulatory approvals required in connection with the Merger Agreement and
the  transactions contemplated thereby,  receipt of opinions  of counsel and the
satisfaction  of  other  customary  closing  conditions.  See  "THE  MERGER   --
Conditions to Consummation of the Merger."
 
    Pinnacle  has filed  applications with the  OTS and the  Federal Reserve for
prior approval  to  consummate  the  Merger.  Such  applications  are  currently
pending.  See "THE MERGER -- Regulatory Approvals." There can be no assurance as
to whether or when the regulatory approvals will be obtained.
 
    All of the conditions  to consummation of  the Merger may  be waived at  any
time  by the party  for whose benefit  they were created,  with the exception of
conditions relating to approval  of the Merger  Agreement by Financial  Security
and  Pinnacle, the receipt of all regulatory approvals, the requirement that the
Registration Statement be declared effective  under the Securities Act, and  the
requirement  that Pinnacle Common Stock be listed on the Nasdaq National Market.
The Merger  Agreement may  be amended  or supplemented  at any  time by  written
agreement  of  the parties  upon  the approval  of  the Pinnacle  Board  and the
Financial Security Board. See "THE MERGER -- Waiver and Amendment."
 
TERMINATION
 
    The Merger Agreement may  be terminated at any  time prior to the  Effective
Time  of the Merger, whether prior to  or after its approval by the stockholders
of Pinnacle and Financial Security, by mutual consent of the parties in writing,
or by either party upon the occurrence of specified events. The Merger Agreement
provides that either party may terminate  the Merger Agreement if the Merger  is
not  consummated by  March 31,  1997, but  the parties  can extend  that date by
mutual consent to a date to be determined by them. The Merger Agreement may also
be terminated as a  result of an  increase or decrease  in the Pinnacle  Average
Stock  Price as discussed herein. In addition, Pinnacle may terminate the Merger
Agreement based on  a decline in  the value of  certain office equipment  leases
held  by Security Federal unless Financial  Security agrees to reduce the Merger
Consideration to  reflect  such  decline. Pinnacle's  and  Financial  Security's
rights to terminate the Merger Agreement are more fully described in "THE MERGER
- --  Merger Consideration,"  "-- Waiver  and Amendment"  and "--  Termination and
Termination Fee" and "BUSINESS OF FINANCIAL SECURITY -- Loan Portfolio."
 
TERMINATION FEE
 
    Under the  Merger  Agreement,  upon  the  occurrence  of  specified  events,
Financial  Security must pay Pinnacle a fee of $600,000 (the "Termination Fee").
The specified events relate generally to the Financial Security Board failing to
support the  Merger  and  unopposed  offers  by,  or  transactions  or  proposed
transactions  with, third parties. The  Termination Fee may discourage competing
offers from  third parties  to acquire  Financial Security  and is  intended  to
increase  the likelihood that the Merger will be consummated. See "THE MERGER --
Termination and Termination Fee."
 
ACCOUNTING TREATMENT
 
    The Merger will be treated as  a purchase for accounting purposes. See  "THE
MERGER -- Accounting Treatment" and "PRO FORMA FINANCIAL STATEMENTS."
 
RESALES OF PINNACLE COMMON STOCK BY AFFILIATES
 
    The  resale of Pinnacle Common Stock issued to "affiliates" (as such term is
defined by Rule  145 as  promulgated by  the SEC  under the  Securities Act)  of
Financial  Security in  connection with  the Merger  will be  subject to certain
restrictions.  Such  shares  may  only  be  sold  pursuant  to  (i)  a  separate
registration  statement relating to  such affiliates' shares  of Pinnacle Common
Stock, (ii) the terms and  conditions of Rule 145  under the Securities Act,  or
(iii)  some other  exemption from  registration. See  "THE MERGER  -- Resales of
Pinnacle Common Stock by Affiliates."

INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    Certain members  of Financial  Security's management  and of  the  Financial
Security  Board have  certain interests  in the Merger  that are  in addition to
their interests as stockholders of Financial Security generally. These interests
include,  among  others,  provisions  in   the  Merger  Agreement  relating   to
indemnification,  and the  continuation of  certain employee  benefits. See "THE
MERGER -- Management and Operations After the Merger." The Merger Agreement also
provides that Pinnacle  will honor the  terms of the  employment agreements  and
change in control agreements between Financial Security and current officers and
employees, and all provisions for vested benefits or other vested amounts earned
or  accrued  through  the  Effective Time.  In  addition,  the  Merger Agreement
provides for  accelerated  vesting  of  Financial  Security  options  and  their
exchange for Pinnacle Common Stock.
 
    The  Financial Security  Board was aware  of these  interests and considered
them among other matters in approving the Merger Agreement and the  transactions
contemplated  thereby. See  "THE MERGER --  Interests of Certain  Persons in the
Merger."
 
CERTAIN TAX CONSEQUENCES OF THE MERGER
 
    It is a condition  to the obligation of  Pinnacle and Financial Security  to
consummate  the Merger that Pinnacle and  Financial Security shall have received
an opinion of  Muldoon, counsel to  Financial Security, to  the effect that  the
Merger  will be treated as a reorganization within the meaning of Section 368(a)
of the Internal  Revenue Code  of 1986, as  amended (the  "Code"). Assuming  the
Merger  is so treated, no gain or loss will be recognized for federal income tax
purposes by Pinnacle or  Financial Security as  a result of the  Merger or by  a
holder of Financial Security Common Stock upon receipt solely of Pinnacle Common
Stock  pursuant to the Merger.  Cash received by a  holder of Financial Security
Common Stock (i)  in consideration of  his or her  shares of Financial  Security
Common Stock pursuant to a Cash Distribution or a Combined Distribution, or (ii)
in  lieu of a fractional share interest in Pinnacle Common Stock will be treated
as received  in  exchange for  such  Financial  Security Common  Stock  or  such
fractional share interest in Pinnacle Common Stock, as the case may be, and gain
or  loss will  be recognized  for federal income  tax purposes,  measured by the
difference between the amount of cash received and the adjusted tax basis of the
share  of  Financial  Security  Common  Stock  surrendered  or  portion  thereof
allocable  to a fractional share interest in  Pinnacle, as the case may be. Such
gain or loss should be capital gain or loss if such share of Financial  Security
Common Stock or fractional share interest in Pinnacle is held as a capital asset
by  such stockholder and will be long-term capital gain or loss if held for more
than one year at the Effective Time. However, if the cash payment has the effect
of a  distribution  of a  dividend,  the  amount of  taxable  income  recognized
generally  will equal the amount of cash received; such income generally will be
taxable as a dividend; and no loss (or other recovery of such stockholder's  tax
basis  for  the shares  of Financial  Security Common  Stock surrendered  in the
exchange) generally will be recognized by such stockholder. The determination of
whether a cash payment has  the effect of a distribution  of a dividend will  be
made  pursuant to  the provisions  and limitations of  Section 302  of the Code,
taking into account the constructive stock ownership rules of Section 318 of the
Code. PINNACLE AND FINANCIAL  SECURITY STOCKHOLDERS ARE  URGED TO CONSULT  THEIR
TAX  ADVISORS CONCERNING  THE SPECIFIC TAX  CONSEQUENCES TO THEM  OF THE MERGER,
INCLUDING THE APPLICABILITY AND EFFECT OF  VARIOUS STATE, LOCAL AND FOREIGN  TAX
LAWS.  See  "THE  MERGER  --  Conditions to  the  Merger"  and  "--  Certain Tax
Consequences of the Merger."
 
CERTAIN DIFFERENCES IN RIGHTS OF STOCKHOLDERS
 
    Upon completion  of  the  Merger, stockholders  of  Financial  Security  who
receive  shares  of Pinnacle  Common Stock  in  exchange for  Financial Security
Common Stock will become stockholders of Pinnacle and their rights as such  will
be  governed by Pinnacle's Certificate of Incorporation and By-laws, and will be
governed by Illinois law. The rights  of stockholders of Pinnacle are  different
in certain respects from the rights of stockholders of Financial Security. For a
summary of these differences, see "COMPARATIVE RIGHTS OF STOCKHOLDERS."
 
                                       15
<PAGE>
COMMON STOCK LISTING
 
    Pinnacle  has agreed to cause the shares  of Pinnacle Common Stock to become
listed on the Nasdaq National  Market including the shares  to be issued in  the
Merger.  The obligation of each of Pinnacle and Financial Security to consummate
the Merger is subject to the listing  of shares of Pinnacle Common Stock on  the
Nasdaq  National  Market. See  "THE MERGER  -- Common  Stock Listing"  and "RISK
FACTORS."
 
DISSENTERS' RIGHTS
 
    Under the provisions of the  Delaware General Corporation Law (the  "DGCL"),
holders  of Financial Security  Common Stock who  assert dissenters' rights will
have a statutory right to have the  value of their shares appraised. To  perfect
this  right, a  holder of  Financial Security  Common Stock  must not  vote such
shares in favor of  the Merger at  the Financial Security  Meeting (this may  be
done  by marking  the proxy either  to vote  against the approval  of the Merger
Agreement or to abstain from  voting thereon or by not  voting at all) and  must
take  such other action as  is required by the provisions  of Section 262 of the
DGCL including  delivering  written  demand  for  appraisal  of  such  Financial
Security  Common Stock. See "THE MERGER  -- Dissenters' Rights" and Appendix III
hereto.
 
               COMPARATIVE STOCK PRICES AND DIVIDEND INFORMATION
 
    Pinnacle Common Stock  and Financial  Security Common Stock  are listed  for
trading on the Nasdaq SCM and the Nasdaq National Market, respectively under the
symbols "PINN" and "FNSC," respectively. The following table sets forth, for the
periods  indicated, the high and  low sales prices per  share of Pinnacle Common
Stock and  Financial Security  Common Stock  on the  Nasdaq SCM  and the  Nasdaq
National Market, respectively, as well as the quarterly cash dividends per share

                                  RISK FACTORS
 
    IN  ADDITION TO THE  OTHER INFORMATION CONCERNING  PINNACLE AND THE PINNACLE
SUBSIDIARY BANKS IN  THIS JOINT PROXY  STATEMENT/PROSPECTUS, THE FOLLOWING  RISK
FACTORS SHOULD BE CONSIDERED CAREFULLY.
 
DEPENDENCE ON KEY PERSONNEL
 
    Pinnacle  is highly  dependent on  the continued  services of  its executive
officers, including Mr.  John J.  Gleason, Chairman of  the Board;  Mr. John  J.
Gleason,  Jr.,  Vice Chairman  of  the Board  and  Chief Executive  Officer; Mr.
William P. Gleason, President and Mr.  Kenneth C. Whitener, Jr., Executive  Vice
President and Chief Investment Officer. Mr. John J. Gleason is the father of Mr.
John  J. Gleason,  Jr. and  Mr. William  P. Gleason.  Pinnacle does  not have an
employment agreement with any of these officers. The loss of the services of any
of these  officers or  of certain  other key  personnel could  adversely  affect
Pinnacle.  Pinnacle  is the  beneficiary of  a  $3,000,000 key-person  term life
insurance policy on Mr. John J. Gleason.
 
HOLDING COMPANY STRUCTURE
 
    Pinnacle  is  a  holding  company  whose  principal  asset  is  all  of  the
outstanding common stock of the Pinnacle Subsidiary Banks. Pinnacle's ability to
pay  its expenses and dividends to  stockholders depends primarily on receipt of
sufficient dividends from  the Pinnacle Subsidiary  Banks. Dividend payments  by
financial  institutions  are  subject  to limitations  under  state  and federal
banking laws and regulations. The Pinnacle Subsidiary Banks had the capacity  to
pay  dividends of  $2.2 million  as of  April 1,  1996 without  prior regulatory
approval and  have the  ability to  pay  future dividends  based on  the  future
earnings  of the Pinnacle  Subsidiary Banks. The  Pinnacle Subsidiary Banks paid
dividends of $10 million  in 1995 and  $2.3 million in  1996 (through March  31,
1996).  Pinnacle believes that  existing federal and  state laws and regulations
will not have a material effect on the ability of the Pinnacle Subsidiary  Banks
to continue paying dividends to Pinnacle in accordance with its dividend policy.
 
INVESTMENT PORTFOLIO
 
    Pinnacle's  investment  portfolio  consists  primarily  of  U.S.  Government
securities. At March 31,  1996, eighty-seven percent  (87%) of total  investment
portfolio  assets  were  invested  in U.S.  Government  securities  and thirteen
percent (13%) were  invested in other  investment securities including  mortgage
backed  and  collateralized  mortgage obligations,  state  and  municipal banks,
corporate bonds and equity securities. At that same date, Pinnacle's holdings of
below investment grade fixed maturity securities were immaterial. The fair value
of Pinnacle's investments varies with changes in economic and market conditions.
Pinnacle's investment portfolio  is accounted for  as available for  sale. As  a
result,  unrealized gains or losses on  securities held by Pinnacle are recorded
as an adjustment  to stockholders'  equity. In  addition, management  undertakes
sales  of securities based on the slope of the yield curve and its assessment of
interest  rate  risk  at  different  maturities.  These  sales  can  result   in
significant  gains  or losses  on the  sale of  securities which  can materially
affect Pinnacle's net income. The fair  value of Pinnacle's securities at  March
31, 1996 exceeded the carrying value by $7.7 million.
 
IMPACT OF GOVERNMENT MONETARY POLICIES
 
    The  earnings  of  banks and  bank  holding  companies are  affected  by the
policies of regulatory authorities including the Federal Reserve which regulates
the money supply.  Among the methods  employed by the  Federal Reserve are  open
market operations in U.S. Government securities, changes in the discount rate on
member  bank borrowings, and changes in reserve requirements against member bank
deposits. These methods are  used in varying  combinations to influence  overall
growth  and distribution of bank loans,  investments and deposits, and their use
may also  affect  interest rates  charged  on loans  or  paid on  deposits.  The
monetary  policies of the Federal  Reserve have had a  significant effect on the
operating results of commercial and savings  banks in the past and are  expected
to continue to do so in the future.
 
                                       22
<PAGE>
ALLOWANCE FOR LOAN LOSSES
 
    The  Pinnacle Subsidiary Banks' allowance for loan losses is maintained at a
level considered adequate by management to absorb anticipated losses. The amount
of future losses  is susceptible  to changes  in economic,  operating and  other
conditions, including changes in interest rates, that may be beyond the Pinnacle
Subsidiary Banks' control and such losses may exceed current estimates. At March
31, 1996, Pinnacle had total nonperforming loans of approximately $7,185,000. At
the  same date, Pinnacle's allowance for loan losses was $6,040,000, or 1.90% of
total loans and eighty-four  percent (84%) of  total nonperforming loans.  There
can  be no  assurance, however,  that such allowance  will be  adequate to cover
actual losses.
 
COMPETITIVE BANKING ENVIRONMENT
 
    Intense competition exists in all aspects of business in which Pinnacle  and
the  Pinnacle  Subsidiary  Banks  are presently  engaged,  not  only  with other
commercial banks and trust companies  but also with thrifts, finance  companies,
personal  loan companies, credit unions,  leasing companies, money market mutual
funds, investment  firms, mortgage  bankers,  and other  financial  institutions
serving the metropolitan areas of Chicago and the Quad-Cities.
 
    Commercial  and  savings  banks compete  on  the basis  of  price, including
interest rates paid on deposits and charged on loans, convenience and quality of
service. This competition includes  banks which are many  times larger than  the
Pinnacle  Bank Subsidiaries, including  banks in the  primary marketing areas of
each Pinnacle  Subsidiary Bank  which have  recently become  affiliated  through
parent  holding companies owning significantly larger banking institutions. Each
Pinnacle Subsidiary  Bank is  encountering increased  competition from  non-bank
financial  institutions. Thrift deposits constitute a substantial portion of all
financial institutions'  deposits  in  Illinois. Thrifts  are  able  to  compete
aggressively  with commercial banks  in the important  area of consumer lending.
Credit unions  and small  loan companies  each are  significant factors  in  the
consumer  loan market. Insurance  companies, investment firms  and retailers are
all  significant  competitors  for  various  types  of  business.  Many  of  the
competitors  of  the  Pinnacle  Subsidiary Banks  are  larger  and  have greater
resources than the Pinnacle Subsidiary Banks,  and there are no assurances  that
the  Pinnacle Subsidiary Banks will be  able to compete effectively against such
companies in the future.
 
CONTROL BY PRINCIPAL STOCKHOLDERS
 
    As of April 30, 1996, the directors and executive officers of Pinnacle owned
approximately fifty-one percent (51%) of the outstanding Pinnacle Common  Stock.
As  of  the  same date,  Pinnacle's  Chairman  of the  Board,  John  J. Gleason,
Pinnacle's Vice Chairman and Chief Executive Officer, John J. Gleason, Jr.,  and
Pinnacle's  Executive Vice  President and  Chief Investment  Officer, Kenneth C.
Whitener, Jr.,  owned in  the  aggregate approximately  30% of  the  outstanding
Pinnacle  Common Stock. While the percentage  ownership of Pinnacle Common Stock
held by Pinnacle's  officers and directors  will be reduced  by the issuance  of
shares  of Pinnacle Common  Stock to holders of  Financial Security Common Stock
pursuant to  the Merger,  the officers  and  directors of  Pinnacle will  own  a
significant  percentage of the issued and  outstanding shares of Pinnacle Common
Stock after  the Effective  Time of  the Merger.  See "DESCRIPTION  OF  PINNACLE
CAPITAL STOCK -- Security Ownership of Management."
 
LIMITED LIQUIDITY OF PINNACLE COMMON STOCK
 
    Although there presently is a public market for the Pinnacle Common Stock on
the  Nasdaq SCM, trading volume is limited.  In 1995, the total volume of shares
traded was 221,188 for a daily average of 864 shares. As of June 30, 1996, total
trading volume in  1996 has been  211,254 shares  for a daily  average of  1,677
shares.  Because  of the  limited trading  volume in  shares of  Pinnacle Common
Stock, the market price for shares of Pinnacle Common Stock could be subject  to
broad  fluctuations  dependent  upon the  demand  for  and supply  of  shares of
Pinnacle Common Stock available for purchase  and sale. In addition, because  of
the limited trading volume in shares of Pinnacle Common Stock, investors may not
be  able  to  liquidate  their  shares  of  Pinnacle  Common  stock  without the
possibility of triggering or suffering a decline in the market price of Pinnacle
Common Stock. While it is a condition
 
                                       23
<PAGE>
to each party's  obligations to  consummate the Merger  Agreement that  Pinnacle
Common Stock be approved for listing on the Nasdaq National Market, there can be
no assurance that trading volume will increase.
 
    In  addition, due to the limited trading volume in shares of Pinnacle Common
Stock, it is possible that  the Pinnacle Average Stock  Price -- the average  of
the closing prices per share of Pinnacle Stock reported by the Nasdaq SCM on the
ten  trading days on which one or  more trades actually occurs immediately prior
to the second business day preceding the consummation of the Merger -- will  not
accurately  reflect the value of Pinnacle Common Stock at the Effective Time. In
the event of strong  demand to purchase shares  of Pinnacle Common Stock  during
the  ten day measuring period prior to  the Effective Time, the Pinnacle Average
Stock Price may be artificially inflated. Similarly, weak demand for the  shares
of  Pinnacle  Common Stock  during the  ten  day measuring  period prior  to the
Effective Time may artificially deflate the Pinnacle Average Stock Price.
 
                                  THE MEETINGS
 
    This Joint Proxy Statement/Prospectus is being provided to the  stockholders
of  Pinnacle and Financial Security in  connection with the Pinnacle Meeting and
the Financial Security Meeting. The meetings will  be held on the date, at  that
time,  in  the  locations  and  to consider  the  matters  set  forth  under the
subheadings "--  Pinnacle  Meeting" and  "--  Financial Security  Meeting".  The
Pinnacle  Board of Directors  and the Financial Security  Board of Directors are
soliciting proxies for use at their respective meetings. The applicable form  of
proxy  is being provided to the respective  holders of Pinnacle Common Stock and
Financial Security Common Stock with this Joint Proxy Statement/ Prospectus.
 
PINNACLE MEETING
 
    MEETING DATE.   The Pinnacle Meeting  will be  held at 2215  York Road,  Oak
Brook,  Illinois 60521, on September 11, 1996,  at 10:00 a.m., Chicago time, and
at the  place,  date  and  time  designated for  any  and  all  adjournments  or
postponements  thereof. This Joint  Proxy Statement/Prospectus is  being sent to
holders of Pinnacle Common Stock and accompanies a form of proxy (the  "Pinnacle
proxy")  which is being solicited by the  Pinnacle Board of Directors for use at
the Pinnacle Meeting and at any and all adjournments or postponements thereof.
 
    RECORD DATE.    The Pinnacle  Board  of Directors  has  fixed the  close  of
business on July 26, 1996 as the date for determining holders of Pinnacle Common
Stock  who will be entitled to notice of,  and to vote at, the Pinnacle Meeting.
Only holders of record of Pinnacle Common Stock at the close of business on  the
Pinnacle  Record Date will be entitled to notice  of and to vote at the Pinnacle
Meeting. As of the Pinnacle Record Date, there were outstanding and entitled  to
vote at the Pinnacle Meeting 4,302,716 shares of Pinnacle Common Stock.
 
    Each  holder of record  of shares of  Pinnacle Common Stock  on the Pinnacle
Record Date will be entitled to cast one vote per share at the Pinnacle  Meeting
on  the proposal to approve and adopt  the Merger Agreement and the transactions
contemplated thereby including the Merger and the issuance by Pinnacle of shares
of Pinnacle Common Stock  to holders of Financial  Security Common Stock  (other
than  Pinnacle or any  of its subsidiaries) electing  to receive Pinnacle Common
Stock in consideration therefor  and Financial Security  stock options that  are
exchanged  for shares  of Pinnacle Common  Stock in connection  with the Merger.
Such vote  may  be  exercised in  person  or  by properly  executed  proxy.  The
presence,  in person or by properly executed proxy, of the holders of a majority
of the  outstanding shares  of Pinnacle  Common Stock  entitled to  vote at  the
Pinnacle  Meeting is necessary to constitute a  quorum. With a quorum, or in the
absence of such, the affirmative vote  of the majority of shares represented  at
the  Pinnacle Meeting may authorize adjournment  of the meeting. Abstentions and
broker non-votes  (the proxies  from brokers  or nominees  indicating that  such
persons  have  not received  instructions from  the  beneficial owners  or other
persons as to certain proposals on
 
                                       24
<PAGE>
which such beneficial owners  or persons are entitled  to vote their shares  but
with  respect to which  the brokers or  nominees have no  discretionary power to
vote without  such  instructions) will  be  treated  as shares  present  at  the
Pinnacle Meeting for purposes of determining the presence of a quorum.
 
    MATTERS  TO BE CONSIDERED.   At the  Pinnacle Meeting, holders  of shares of
Pinnacle Common Stock will vote on the proposal to approve and adopt the  Merger
Agreement  and the transactions contemplated  thereby, including the Merger, and
the issuance by Pinnacle of shares of Pinnacle Common Stock to former holders of
Financial Security Common Stock (other than Pinnacle or any of its subsidiaries)
electing  to  receive  Pinnacle  Common  Stock  in  consideration  therefor  and
Financial  Security  stock options  that are  exchanged  for shares  of Pinnacle
Common Stock in  connection with the  Merger. Pursuant to  Section 11.20 of  the
IBCA,  Pinnacle stockholders would  not be entitled  to vote on  the proposal to
approve and adopt the Merger Agreement if the shares of Pinnacle Common Stock to
be issued in connection with the Merger  did not exceed twenty percent (20%)  of
the  shares  of  Pinnacle  Common Stock  outstanding  immediately  prior  to the
Effective Time. While Pinnacle Common  Stock must constitute fifty-five  percent
(55%)  of the aggregate consideration payable by Pinnacle in connection with the
Merger, it is  not certain  how many  shares of  Pinnacle Common  Stock will  be
issued  in connection with the Merger and whether such shares will exceed twenty
percent (20%) of  the shares  of Pinnacle Common  Stock outstanding  immediately
prior  to the Effective Time.  As a result, Pinnacle  has scheduled the Pinnacle
Meeting to approve and adopt the Merger Agreement. Approval and adoption of  the
Merger  Agreement  is a  condition  to, and  required  for, consummation  of the
Merger. See "THE MERGER -- Conditions to the Merger."
 
    VOTE REQUIRED.   The affirmative vote  of the holders  of two-thirds of  the
outstanding  shares  of  Pinnacle  Common Stock  is  required  for  approval and
adoption of the  Merger Agreement. Therefore,  abstentions and broker  non-votes
will  have the same effect  as votes against the approval  of the Merger. With a
quorum, or in the  absence of such,  the affirmative vote of  a majority of  the
shares  represented at the Pinnacle Meeting may authorize the adjournment of the
meeting.
 
    A FAILURE TO VOTE,  EITHER BY NOT  RETURNING THE ENCLOSED  PROXY CARD OR  BY
CHECKING  THE  "ABSTAIN"  BOX THEREON,  WILL  HAVE  THE SAME  EFFECT  AS  A VOTE
"AGAINST" THE MERGER AGREEMENT.
 
    SECURITY OWNERSHIP.  As of the Pinnacle Record Date, directors and executive
officers of Pinnacle held in the  aggregate 2,192,632 shares of Pinnacle  Common
Stock (excluding option shares), or approximately 50.96% of the then outstanding
shares  of Pinnacle Common Stock  entitled to vote at  the Pinnacle Meeting. The
directors and executive officers of  Pinnacle have indicated their intention  to
vote  such shares in favor of the  approval and adoption of the Merger Agreement
at the Pinnacle  Meeting. Accordingly, holders  of an additional  15.71% of  the
outstanding  shares of  Pinnacle Common  Stock entitled  to vote  must vote such
shares in favor of the Merger Agreement for such proposal to be approved. As  of
such  date,  neither  Financial  Security  and  its  subsidiaries,  nor,  to the
knowledge of  Financial  Security,  the  directors  and  executive  officers  of
Financial Security and their affiliates, held any outstanding shares of Pinnacle
Common Stock.
 
    Pursuant  to the  Merger Agreement, affiliates  of Pinnacle  or the Pinnacle
Subsidiary Banks, including officers, employees, directors or holders of greater
than ten percent (10%) of the  outstanding shares of Pinnacle Common Stock  have
agreed to not purchase any Pinnacle Common Stock during the thirty business days
prior to the consummation of the Merger.
 
    PROXIES.   Shares of Pinnacle Common  Stock represented by properly executed
proxies received prior to or at  the Pinnacle Meeting will, unless such  proxies
have  been revoked,  be voted  at the Pinnacle  Meeting and  any adjournments or
postponements thereof,  in accordance  with the  instructions indicated  in  the
proxies. IF NO INSTRUCTIONS ARE INDICATED ON A PROPERLY EXECUTED PINNACLE PROXY,
THE  SHARES WILL BE  VOTED IN FAVOR OF  THE APPROVAL AND  ADOPTION OF THE MERGER
AGREEMENT.
 
    Any Pinnacle proxy given pursuant to  this solicitation or otherwise may  be
revoked  by the  person giving  it at  any time  before it  is voted,  either by
delivering to the Corporate Secretary of Pinnacle a
 
                                       25
<PAGE>
written notice of revocation bearing a later date than the date of the  Pinnacle
proxy  or a later  dated proxy relating to  the same shares  or by attending the
Pinnacle Meeting and voting in person.  Attendance at the Pinnacle Meeting  will
not in itself constitute the revocation of a proxy.
 
    The  Pinnacle Board  is not aware  of any business  to be acted  upon at the
Pinnacle Meeting other than as described  herein. If however, other matters  are
properly  brought before  the meeting, or  any adjournment  thereof, the persons
appointed as proxies will have the  discretion to vote or act thereon  according
to their best judgment.
 
    In  addition to solicitation  by mail, directors,  officers and employees of
Pinnacle, who  will  not be  specifically  compensated for  such  services,  may
solicit  proxies from the stockholders of  Pinnacle, personally or by telephone,
telegram  or  other   forms  of  communication.   Brokerage  houses,   nominees.
fiduciaries  and  other  custodians  will  be  requested  to  forward soliciting
materials to  beneficial owners  and  will be  reimbursed for  their  reasonable
expenses  incurred in  sending proxy  materials to  beneficial owners.  See "THE
MERGER -- Expenses."
 
    HOLDERS OF PINNACLE COMMON  STOCK ARE REQUESTED TO  COMPLETE, DATE AND  SIGN
THE  ACCOMPANYING  PROXY AND  RETURN  IT PROMPTLY  TO  PINNACLE IN  THE ENCLOSED
POSTAGE-PAID ENVELOPE.
 
FINANCIAL SECURITY MEETING
 
    MEETING DATE.   The Financial Security  Meeting will be  held at 1209  North
Milwaukee  Avenue, Chicago,  Illinois September  11, 1996  at 3:00  p.m. Chicago
time, and at the place, date and time designated for any and all adjournments or
postponements thereof. This Joint Proxy  Statement/ Prospectus is being sent  to
holders  of Financial Security Common Stock and accompanies a form of proxy (the
"Financial Security proxy") which is  being solicited by the Financial  Security
Board  for use at the Financial Security Meeting and at any and all adjournments
or postponements thereof.
 
    RECORD DATE.  The Financial Security  Board has fixed the close of  business
on  July 26,  1996 as  the date  for determining  holders of  Financial Security
Common Stock who will be  entitled to notice of, and  to vote at, the  Financial
Security  Meeting. Only holders of record  of Financial Security Common Stock at
the close of  business on  the Financial Security  Record Date  are entitled  to
notice  of and to  vote at the  Financial Security Meeting.  As of the Financial
Security Record Date there were outstanding and entitled to vote at the Security
Federal Meeting 1,550,846 shares of Financial Security Common Stock.
 
    Each holder of record  of shares of Financial  Security Common Stock on  the
Financial  Security Record  Date will  be entitled  to one  vote for  each share
registered in  his or  her  name on  each  matter presented  to  a vote  of  the
stockholders  at the Financial  Security Meeting, except  as described below. As
provided in Financial Security's Certificate of Incorporation, recordholders  of
Financial  Security Common Stock  who beneficially own in  excess of ten percent
(10%) of  the  outstanding  shares  of  Financial  Security  Common  Stock  (the
"Financial  Security Limit") are  not entitled to  any vote with  respect to the
shares held in excess  of the Financial  Security Limit. A  person or entity  is
deemed  to beneficially own shares owned by an affiliate of, as well as a person
acting in concert with, such person or entity. A vote may be exercised in person
or by properly executed proxy. The  presence, in person or by properly  executed
proxy,  of the holders of a majority of outstanding shares of Financial Security
Common Stock entitled to vote at the Financial Security Meeting is necessary  to
constitute  a quorum. With a quorum, or  in the absence of such, the affirmative
vote of a majority of shares  represented at the Financial Security Meeting  may
authorize  adjournment of the meeting. Abstentions  and broker non-votes will be
treated as shares present at the Financial Security Meeting for determining  the
presence of the quorum.
 
    MATTERS  TO  BE  CONSIDERED.   At  the Financial  Security  Special Meeting,
holders of shares of Financial Security Common Stock will vote on a proposal  to
approve  and  adopt  the  Merger  Agreement  and  the  transactions contemplated
thereby, including the Merger.
 
                                       26
<PAGE>
    VOTE REQUIRED.  The  affirmative vote of  the holders of  a majority of  the
outstanding  shares of Financial Security Common  Stock is required for approval
and adoption of the Merger Agreement. Therefor, abstentions and broker non-votes
will have the same effect as votes against the approval of the Merger Agreement.
With a quorum, or in the absence of such, the affirmative vote of a majority  of
the  shares  represented at  the Financial  Security  Meeting may  authorize the
adjournment of  the meeting.  Approval  of the  Merger  by the  stockholders  of
Financial  Security is  a condition  to, and  required for,  consummation of the
Merger. See "THE MERGER -- Conditions to the Merger."
 
    A FAILURE TO VOTE,  EITHER BY NOT  RETURNING THE ENCLOSED  PROXY CARD OR  BY
CHECKING  THE  "ABSTAIN"  BOX THEREON,  WILL  HAVE  THE SAME  EFFECT  AS  A VOTE
"AGAINST" THE MERGER AGREEMENT.
 
    SECURITY OWNERSHIP.   As of the  Financial Security Record  Date, 1996,  the
directors  and executive  officers of Financial  Security held  in the aggregate
225,187 shares of Financial Security Common Stock (excluding option shares),  or
approximately  14.52%  of the  voting power  of the  then outstanding  shares of
Financial Security  Common Stock  entitled  to vote  at the  Financial  Security
Meeting.  The  directors  and  executive  officers  of  Financial  Security have
indicated their  intention to  vote such  shares in  favor of  the approval  and
adoption of the Merger Agreement at the Financial Security Meeting. Accordingly,
holders  of an additional 35.49% of the outstanding shares of Financial Security
Common Stock entitled  to vote  must vote  such shares  in favor  of the  Merger
Agreement  in order for such  proposal to be approved.  As of such date, neither
Pinnacle and its subsidiaries, nor, to the knowledge of Pinnacle, the  directors
and  executive officers of  Pinnacle and their  affiliates, held any outstanding
shares of Financial Security Common Stock.
 
    Pursuant to the Security Federal Savings and Loan Association Employee Stock
Ownership Plan (the "ESOP"), each participant is entitled to direct the  trustee
with  respect  to  voting  of  the shares  of  Financial  Security  Common Stock
allocated to such participant's accounts. First Bankers Trust Company, N.A.  has
been  appointed  as the  corporate trustee  for the  ESOP (the  "ESOP Trustee").
Subject to its duties under the Employee Retirement Income Security Act of 1974,
as amended ("ERISA"), the  ESOP Trustee will vote  all allocated shares held  in
the  ESOP  in accordance  with the  instructions received.  As of  the Financial
Security Record Date, 51,439 of the 115,909 shares of Financial Security  Common
Stock in the ESOP had been allocated to participating employees. Under the ESOP,
unallocated  shares  held in  the suspense  account  will be  voted by  the ESOP
Trustee in  a manner  calculated  to most  accurately reflect  the  instructions
received  from  participants  regarding  the  allocated  stock,  subject  to the
provisions of ERISA.
 
    PROXIES.  Shares of Financial Security Common Stock represented by  properly
executed  proxies received prior  to or at the  Financial Security Meeting will,
unless such  proxies have  been  revoked, be  voted  at the  Financial  Security
Meeting  and any  adjournments or postponements  thereof in  accordance with the
instructions indicated in  the proxies. If  no instructions are  indicated on  a
properly executed Financial Security proxy, the shares will be voted in favor of
the approval and adoption of the Merger Agreement.
 
    Any  Financial  Security  proxy  given  pursuant  to  this  solicitation  or
otherwise may be revoked by the person giving it at any time before it is  voted
by  delivering to the Corporate Secretary of Financial Security a written notice
of revocation bearing a later date than the Financial Security proxy or a  later
dated proxy relating to the same shares of Financial Security Common Stock or by
attending the Financial Security Meeting and voting in person. Attendance at the
Financial  Security Meeting  will not in  itself constitute the  revocation of a
proxy. If  a  stockholder's  shares are  not  registered  in his  own  name  the
stockholder  will need additional  documentation from the  record holder to vote
personally at the Financial Security Meeting.
 
    The Financial Security Board is not aware  of any business to be acted  upon
at  the Financial Security Meeting other  than as described herein. IF, HOWEVER,
OTHER MATTERS ARE PROPERLY BROUGHT BEFORE THE FINANCIAL SECURITY MEETING, OR ANY
ADJOURNMENT THEREOF, THE PERSONS APPOINTED  AS PROXIES WILL HAVE THE  DISCRETION
TO VOTE OR ACT THEREON ACCORDING TO THEIR BEST JUDGEMENT.

    In  addition to  solicitation by  mail, Morrow  & Co.,  a proxy solicitation
firm, will assist  Financial Security  in soliciting proxies  for the  Financial
Security  Meeting  and  will  be  paid  a  fee  estimated  to  be  $5,000,  plus
out-of-pocket expenses. Proxies may also be solicited personally or by telephone
by directors, officers,  and employees of  Financial Security, who  will not  be
specifically   compensated  for  such   services.  Brokerage  houses,  nominees,
fiduciaries and  other  custodians  will  be  requested  to  forward  soliciting
materials  to Financial  Security beneficial owners  and will  be reimbursed for
their reasonable  expenses  incurred in  sending  proxy material  to  beneficial
owners.  The cost of  soliciting proxies in  the form enclosed  herewith will be
borne by Financial Security. See "THE MERGER -- Expenses."

AGREEMENT, WHICH IS ATTACHED AS APPENDIX I AND INCORPORATED BY REFERENCE HEREIN.
ALL STOCKHOLDERS ARE URGED TO READ THE MERGER AGREEMENT IN ITS ENTIRETY.
 
GENERAL
 
    Pursuant to the Merger Agreement, Financial Security will be merged with and
into Pinnacle with Pinnacle  being the surviving corporation  in the Merger.  As
soon  as possible after  the conditions to consummation  of the Merger described
below have been satisfied  or waived, and unless  the Merger Agreement has  been
terminated as provided below, Pinnacle and Financial Security will file articles
of merger with the Secretary of State of the State of Illinois and a certificate
of  merger with the Secretary of State of  the State of Delaware for the Merger.
The Merger will become effective at that  time and on the date specified in  the
articles of merger and the certificate of merger.
 
    Upon  consummation of  the Merger,  and depending  upon their  election, the
stockholders of Financial Security will be entitled to receive either the  Stock
Distribution,   the  Cash   Distribution,  or   the  Combined   Distribution  in
consideration for  their shares  of  Financial Security  Common Stock  held  and
thereupon shall cease to be stockholders of Financial Security, and the separate
existence and corporate organization of Financial Security shall cease. Pinnacle
shall  succeed to  all the  rights, responsibilities  and property  of Financial
Security. The members of the Board of Directors of Pinnacle and the officers  of
Pinnacle  immediately prior  to the  Effective Time will  be the  members of the
Board of Directors and the officers of Pinnacle immediately after the  Effective
Time. The name of the surviving corporation in the Merger will be "Pinnacle Banc
Group, Inc.".
 
BACKGROUND OF THE MERGER
 
    Originally  chartered  in 1907  as a  federally-chartered building  and loan
association, Security Federal  converted to  a stock form  of organization  (the
"Conversion")  and formed Financial Security as  its holding company in December
1992. The period  subsequent to  the Conversion has  been one  of continued  and
substantial   change  in  the  banking  industry,  characterized  by  heightened
regulatory scrutiny, and intensifying competition and consolidation.
 
    As part of  Financial Security's continuing  efforts to enhance  stockholder
value  and in response  to the changing  banking industry environment, Financial
Security interviewed a number of investment  banking firms during late 1994  and
1995.    On   September   21,   1995,    Financial   Security   selected   Hovde
 
                                       28
<PAGE>
to provide investment advisory services.  In particular, the Financial  Security
Board  hired Hovde to provide  direction and guidance with  regard to methods of
enhancing stockholder  value  on  a going  forward  basis,  including  remaining
independent,  acquiring  another financial  institution  or branches  of another
financial institution, or being acquired.
 
    In mid-November  1995, the  Financial Security  Board, taking  into  account
Hovde's  previous presentation  as well as  the continuing  consolidation of the
banking industry,  particularly  in the  Midwest,  decided to  explore  possible
merger  opportunities with another financial institution as a possible method of
enhancing stockholder value.  The Financial Security  Board authorized Hovde  to
identify  prospective merger partners, provide  advice regarding any preliminary
indications of interest, and assist in any negotiations that might occur.  Hovde
contacted approximately 32 potential merger partners, which were chosen based on
criteria  established  by Hovde  and Financial  Security. As  a result  of these
contacts, 24 financial institutions entered into confidentiality agreements with
Financial Security  and  received  confidential  information  packets  regarding
Financial  Security.  Financial  Security  received  preliminary  expressions of
interest, which were within parameters set by Financial Security and Hovde, from
five potential acquirors. Additional  parties submitted indications of  interest
that were unacceptable to Financial Security because of pricing levels or timing
constraints.  Subsequent  to  conducting  preliminary  due  diligence, Financial
Security received three written  and two verbal  updated or revised  preliminary
indications of interest.
 
    On  March 1, 1996, the Financial Security Board met to consider, among other
things, the preliminary indications of interest.  At this meeting, a report  was
presented  by Hovde discussing  the preliminary indications  of interest and the
potential acquirors. The presentation  included information regarding  potential
acquirors, a review of the preliminary terms of each proposal and an analysis of
numerous other recent transactions involving thrift institutions of similar size
and  involving thrift institutions in the  Midwest. The Financial Security Board
authorized Hovde to continue to develop the terms of the preliminary indications
of interest.
 
    On March 11, 1996, the Financial Security Board met to further consider  two
of  the five indications of interest  and interviewed the two institutions which
submitted  such  indications  of  interest.   At  the  meeting,  Hovde  made   a
presentation  regarding the  terms and  structure of  the proposed transactions.
Additionally, Financial Security's legal  counsel made a presentation  regarding
the   Financial  Security  Board's  fiduciary  responsibilities.  Following  the
presentation and a discussion,  the Financial Security  Board decided to  pursue
Pinnacle's  indication of interest which provided for the exchange of shares for
consideration of $27.87 per share in stock  or a combination of cash and  stock;
however,  the Financial Security  Board authorized such  action only if Pinnacle
increased its offer to $28.50 per  share. The Financial Security Board  declined
to  pursue the  second indication of  interest primarily because  of the pricing
level, which was  below the Pinnacle  offer, the form  of consideration and  tax
implications of such consideration.
 
    On March 14, 1996, the Financial Security Board held its regular meeting and
legal  counsel and its  financial advisors were present  by phone. The Financial
Security Board considered the revised offer of Pinnacle which had been increased
to $28.50. At  the meeting,  Hovde presented the  following financial  analysis:
contribution  analysis, financial  implications of the  acquisition analysis and
comparative stockholder rates of return  analysis. The Financial Security  Board
discussed these items as well as other material items of the Pinnacle offer. The
Financial  Security  Board authorized  the  negotiation of  a  definitive merger
agreement by management, Hovde and its legal counsel.
 
    During the  next  several weeks  the  parties conducted  due  diligence  and
negotiated  specific terms and conditions of the  Merger. On April 11, 1996, the
Financial Security  Board held  its  regular meeting  to consider  the  proposed
merger  with Pinnacle.  At the meeting,  Financial Security's  legal counsel and
Hovde made  presentations  regarding  the proposed  transaction.  The  Financial
Security  Board  was  presented  a draft  merger  agreement,  and  the Financial
Security Board reviewed its terms and  conditions with legal counsel. The  Hovde
presentation  included  a comparative  analysis  of numerous  other transactions
involving institutions  with  similar  asset  size  and  equity  levels  located
nationwide,
 
                                       29
<PAGE>
in  the  Midwest  and in  Illinois  only.  In addition,  the  Hovde presentation
included a contribution analysis, a  discounted cash flow analysis, a  financial
implications  to  stockholders analysis,  and  a comparative  stockholder return
analysis  discussed  in  greater  detail   below.  At  the  conclusion  of   its
presentation Hovde gave its opinion that the Merger Consideration to be received
was  fair, from a financial point of view, to Financial Security's stockholders.
Following the presentations and  a discussion by  the Financial Security  Board,
the Financial Security Board authorized management and legal counsel to finalize
the negotiations of the definitive agreement.
 
    On  April 22,  1996, the  Financial Security  Board held  a special meeting.
After a discussion of the final terms  of the Merger Agreement and an update  by
Hovde  of its financial presentation, the  Financial Security Board approved the
Merger Agreement,  authorized  its execution  and  recommended approval  of  the
Merger  Agreement  by  stockholders.  Subsequently,  the  Merger  Agreement  was
executed and a press release was issued announcing the Merger.
 
REASONS FOR THE MERGER
 
    PINNACLE.  Pinnacle's corporate objective is to enhance shareholder value by
effectively leveraging Pinnacle's equity base  and to achieve returns on  equity
and  assets  in  excess of  peer  group  performance. One  of  the  methods that
management utilizes to  accomplish this  objective is the  acquisition of  other
financial   institutions.  In  negotiating  the  terms  of  the  Merger  and  in
considering its recommendation  for the  approval of the  Merger Agreement,  the
Pinnacle  Board considered a  number of factors,  including, without limitation:
the business,  operations and  financial condition  of Financial  Security;  the
prospects  of  the  combined  institution;  the  increased  market  presence and
enhanced opportunities for  growth made possible  by the Merger;  the growth  of
Pinnacle's  loan portfolio  and attendant increase  in Pinnacle's  loan to asset
ratio; an increase  in the  liquidity of shares  of Pinnacle  Common Stock;  the
ability  to  consummate the  acquisition with  a minimal  increase in  debt; the
growth of Pinnacle's total assets to a figure in excess of one billion  dollars;
and  the expectation that the Merger generally will be a tax-free transaction to
Pinnacle and its stockholders. In view  of the variety of factors considered  in
connection with its evaluation of the Merger, the Pinnacle Board did not find it
practicable  to, and did  not, quantify or otherwise  attempt to assign relative
weights to the specific  factors considered in  reaching its determination.  THE
PINNACLE  BOARD  BELIEVES  THAT THE  MERGER  IS  IN THE  BEST  INTERESTS  OF ITS
STOCKHOLDERS AND RECOMMENDS THE STOCKHOLDERS  VOTE FOR ADOPTION AND APPROVAL  OF
THE MERGER AGREEMENT.
 
    FINANCIAL  SECURITY.  The  Financial Security Board,  with the assistance of
outside financial  and legal  advisors has  evaluated the  financial, legal  and
market  conditions bearing on the decision to recommend the Merger. The terms of
the Merger,  including the  price, are  a result  of arm's  length  negotiations
between  representatives  of Pinnacle  and Financial  Security. In  reaching its
determination that the Merger Agreement is fair to, and in the best interest  of
Financial Security and holders of Financial Security Common Stock, the Financial
Security  Board  considered a  number of  factors,  from a  short and  long term
perspective, including, without limitation, the following:
 
    (i) the Financial Security Board's familiarity with and review of  Financial
        Security's   business,  financial  condition,   results  of  operations,
        management, and prospects,  including but not  limited to its  potential
        growth,  development, productivity  and profitability,  and the business
        risks associated therewith;
 
    (ii) the environment in which Financial Security currently operates and will
         be likely  to  operate in  the  future, including  national  and  local
         economic   conditions,  the   competitive  environment   for  financial
         institutions generally, the  increased regulatory  burden on  financial
         institutions  generally  and  the  trend  toward  consolidation  in the
         financial  services  industry,  particularly  in  Financial  Security's
         market area;
 
   (iii) information  concerning  the  business, operations,  asset  quality and
         prospects of Pinnacle;
 
                                       30
<PAGE>
   (iv) the oral and written presentations and the oral and written opinions  of
        Financial   Security's  financial   advisor,  Hovde,   that  the  Merger
        Consideration was fair to the holders of Financial Security Common Stock
        from a financial point of view;
 
    (v) the Financial Security  Board's belief  that the terms  of the  proposed
        form  of Merger Agreement with Pinnacle were attractive in that it would
        allow Financial Security stockholders to elect to receive stock, cash or
        a  combination  thereof  as  specified  in  the  Merger  Agreement   and
        potentially  permit  stockholders who  receive  stock to  defer  any tax
        liability and to  become stockholders in  Pinnacle, an institution  with
        strong operations, management, and earnings performance;
 
   (vi) the  expectation that Pinnacle will  continue to provide quality service
        to the  community and  customers served  by Financial  Security and  the
        expectation  that  Pinnacle  would  likely  maintain  Security Federal's
        offices;
 
   (vii) the  compatibility   of   the  respective   business   and   management
         philosophies of Financial Security and Pinnacle;
 
  (viii) the  addition of products and services,  as well as greater convenience
         through additional locations, which will be afforded Financial Security
         customers as a result of the Merger; and
 
   (ix) the alternative  strategic  courses  available  to  Financial  Security,
        including  remaining  independent  or  exploring  other  indications  of
        interest from other potential acquirors.
 
    Certain members of  the Board  of Directors  have interests  in addition  to
their  interests as stockholders generally, including certain payments that will
be made as  a result  of the  Merger under  various benefit  plans of  Financial
Security. See "-- Interests of Certain Persons in the Merger."
 
    In  view  of  the  variety  of factors  considered  in  connection  with its
evaluation of  the  Merger,  the  Financial  Security  Board  did  not  find  it
practicable  to, and did  not, quantify or otherwise  attempt to assign relative
weights to the specific  factors considered in  reaching its determination.  THE
FINANCIAL  SECURITY BOARD OF DIRECTORS  BELIEVES THAT THE MERGER  IS IN THE BEST
INTERESTS OF ITS STOCKHOLDERS AND RECOMMENDS THE STOCKHOLDERS VOTE FOR  ADOPTION
AND APPROVAL OF THE MERGER AGREEMENT.
 
RECOMMENDATIONS OF THE BOARDS OF DIRECTORS

OPINION OF FINANCIAL SECURITY'S FINANCIAL ADVISOR
 
    Hovde has delivered to the Financial Security Board its opinion that,  based
upon  and subject to the various considerations set forth in its written opinion
dated April 22, 1996, the Merger Consideration is fair from a financial point of
view to the stockholders  of Financial Security as  of such date. In  requesting
Hovde's  advice and opinion,  no limitations were  imposed by Financial Security
upon Hovde with respect to the investigations made or procedures followed by  it
in rendering its opinion.
 
    The  opinion has been updated as of July  26, 1996 and the full text of that
opinion which  describes  the  procedures followed,  assumptions  made,  matters
considered  and  limitations on  the review  undertaken,  is attached  hereto as
Appendix II. Stockholders of Financial Security should read this opinion in  its
entirety.
 
    HOVDE'S  OPINION IS DIRECTED ONLY TO THE FAIRNESS, FROM A FINANCIAL POINT OF
VIEW, OF THE MERGER CONSIDERATION, AND  DOES NOT CONSTITUTE A RECOMMENDATION  TO
ANY  STOCKHOLDER OF FINANCIAL SECURITY AS TO HOW SUCH STOCKHOLDER SHOULD VOTE AT
THE FINANCIAL SECURITY SPECIAL MEETING. THE SUMMARY OF THE OPINION OF HOVDE  SET
FORTH  IN THIS JOINT PROXY STATEMENT/ PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE FULL TEXT OF SUCH OPINION.
 
    The following  is a  brief summary  of the  analyses performed  by Hovde  in
connection with its fairness opinion:
 
    During  the course  of its engagement,  and as  a basis for  arriving at its
opinion, Hovde reviewed  and analyzed  material bearing upon  the financial  and
operating  condition of Pinnacle and Financial Security and material prepared in
connection with the Merger,  including, among other  things, the following:  (i)
the  Merger Agreement;  (ii) certain  publicly available  information concerning
Financial Security and Pinnacle, including the consolidated financial statements
of Financial Security and  Pinnacle for each of  the three years ended  December
31,  1995, and the balance sheet and  income statement of Financial Security and
Pinnacle for the  subsequent quarterly period  ended March 31,  1996; (iii)  the
nature  and terms of recent acquisition and merger transactions involving thrift
institutions and  thrift  holding  companies that  Hovde  considered  reasonably
similar to Financial Security in size, financial character, operating character,
historical  performance  and geographic  market;  and (iv)  financial  and other
information provided  to  Hovde by  the  management of  Pinnacle  and  Financial
Security.  Hovde  conducted  meetings  with  members  of  senior  management  of
Financial Security and Pinnacle for  purposes of reviewing the future  prospects
of  Financial Security and Pinnacle. Hovde also took into account its experience
in other transactions, as  well as its knowledge  of the commercial banking  and
thrift industries and its general experience in securities valuations.
 
    In  rendering its opinion, Hovde  assumed, without independent verification,
the accuracy and completeness of the financial and other information it reviewed
and has relied upon the accuracy of the representations of the parties contained
in the  Merger Agreement.  Hovde  has not  made  any independent  evaluation  or
appraisal  of any properties, assets or liabilities of Financial Security. Hovde
assumed and relied upon the accuracy and completeness of the publicly  available
and  other  financial and  other  information provided  to  it, relied  upon the
representations and warranties of Pinnacle and Financial Security made  pursuant
to the Merger Agreement, and did not independently attempt to verify any of such
information.
 
    In  connection  with  its  opinion, Hovde  performed  various  analyses with
respect to  Financial  Security.  The  following is  a  brief  summary  of  such
analyses,  certain of  which were presented  to the Financial  Security Board by
Hovde prior to the execution of  the Merger Agreement. These analyses have  been
updated as of the mailing of this Joint Proxy Statement/Prospectus.
 
    ANALYSIS  OF  THE MERGER  CONSIDERATION.   Hovde reviewed  the value  of the
Merger Consideration  to be  received by  each Financial  Security  stockholder.
Hovde calculated that the Merger Consideration
 
                                       32
<PAGE>
equated  to approximately 121.62% of Financial Security's fully diluted tangible
book value  at  December  31,  1995, a  multiple  of  approximately  22.3  times
Financial  Security's earnings for the 12 months  ended December 31, 1995, and a
premium to core deposits of approximately 5.18%.
 
    SUMMARY OF  PROPOSALS.   Hovde  summarized the  sales process,  the  parties
contacted and the level of interest expressed by each party, including the value
of  the  aggregate  consideration  offered  to  the  stockholders  of  Financial
Security.
 
    Hovde also compared the significant terms  of the Pinnacle proposal to  that
of   the  other  bidders  submitting  proposals,  including  the  value  of  the
consideration offered. This analysis showed, among other things, that the  value
of  the Pinnacle proposal of $28.50 per share of Financial Security Common Stock
was considered higher  than the value  per share offered  by the other  bidders,
especially  given that the stockholders of  Financial Security could elect three
different options with respect  to the form of  consideration, including an  all
stock,  tax-deferred exchange. Hovde  examined the trading  price and volume for
Pinnacle Common Stock and the  relationship between the trading  characteristics
of  the common  stocks of the  other companies,  as well as  to a  peer group of
comparable companies.
 
    ANALYSIS OF SELECTED MERGERS.  As part of its analysis, Hovde reviewed  four
sets  of mergers: (i) selected  mergers involving thrifts headquartered anywhere
in the United States  announced between January  1, 1988 and  March 31, 1996  in
which  the total  assets of the  seller were  greater than $100  million and the
tangible  equity/asset  ratio  was  greater  than  twelve  percent  (12%)   (the
"Nationwide  Mergers"); (ii) selected mergers involving thrifts headquartered in
the Midwest announced between January  1, 1992 and March  31, 1996 in which  the
total  assets of  the seller  were greater  than $100  million and  the tangible
equity/asset ratio  was  greater  than twelve  percent  (12%)  (the  "Midwestern
Mergers");  (iii)  all  mergers  involving  thrifts  headquartered  in  Illinois
completed since January 1, 1993 and announced before March 31, 1996 in which the
total assets  of the  seller were  greater than  $100 million  and the  tangible
equity/asset  ratio  was  greater  than  twelve  percent  (12%)  (the  "Illinois
Mergers"); and (iv) selected mergers involving thrifts headquartered anywhere in
the United States announced between January 1, 1988 and March 31, 1996 in  which
the  total  assets  of  the  seller  were  greater  than  $100  million  and the
non-performing assets to  total assets ratio  was between two  percent (2%)  and
five  percent (5%) (the "High Non-Performers"). The Nationwide Mergers consisted
of 40 mergers involving thrifts headquartered anywhere in the United States; the
Midwestern Mergers  consisted of  13  mergers of  thrifts headquartered  in  the
Midwest;  the  Illinois  Mergers  consisted  of  four  thrifts  headquartered in
Illinois; and the High Non-Performers consisted of 61 mergers involving  thrifts
headquartered  anywhere  in  the  United  States.  For  each  transaction, Hovde
calculated the  multiple of  the  offer value  to  the acquired  company's:  (i)
earnings  per  share  ("EPS")  for  the  twelve  months  preceding  ("LTM")  the
announcement date of the transaction; (ii) book value per share; (iii)  tangible
book value per share; and (iv) the tangible book premium to core deposits.
 
    The  calculations for the Nationwide Mergers yielded a range of multiples of
offer value to  LTM EPS of  10.0 times to  44.6 times, with  an average of  19.0
times  and a median of 16.4  times; a range of multiples  of offer value to book
value of 0.77 times to 1.44 times, with an average of 1.19 times and a median of
1.22 times; a range of multiples of  offer value to tangible book value of  0.77
times  to 1.44 times, with an average of  1.20 times and a median of 1.23 times;
and a range of tangible book premium to core deposits of -3.70% to 13.48%,  with
an average of 4.74% and a median of 5.44%.
 
    The  calculations for the Midwestern Mergers yielded a range of multiples of
offer value to  LTM EPS of  12.9 times to  44.6 times, with  an average of  22.0
times  and a median of 17.0  times; a range of multiples  of offer value to book
value of 1.04 times to 1.36 times, with an average of 1.22 times and a median of
1.23 times; a range of multiples of  offer value to tangible book value of  1.04
times  to 1.36 times, with an average of  1.22 times and a median of 1.23 times;
and a range of multiples of tangible  book premium to core deposits of 1.47%  to
6.61%, with an average of 5.03% and a median of 5.44%.
 
    The  calculations of  the Illinois Mergers  yielded a range  of multiples of
offer value to  LTM EPS of  12.9 times to  27.6 times, with  an average of  17.6
times  and a median of 14.9  times; a range of multiples  of offer value to book
value of 1.04 times to 1.36 times, with an average of 1.19 times and a median of
 
                                       33
<PAGE>
1.19 times; a range of multiples of  offer value to tangible book value of  1.04
times  to 1.36 times, with an average of  1.19 times and a median of 1.19 times;
and a range of tangible book premium to core deposits of 1.47% to 5.44%, with an
average of 3.77% and a median of 4.09%.
 
    The calculations of the High Non-Performers yielded a range of multiples  of
offer value to LTM EPS of 4.6 times to 37.1 times, with an average of 16.4 times
and a median of 14.2 times; a range of multiples of offer value to book value of
0.43  times to 1.94  times, with an average  of 1.28 times and  a median of 1.28
times; a range of multiples of offer value to tangible book value of 0.63  times
to  2.06 times, with an average of 1.35 times  and a median of 1.29 times; and a
range of tangible book  premium to core  deposits of -3.70%  to 14.03%, with  an
average of 3.61% and a median of 3.10%.
 
    Hovde  compared  these multiples  with the  corresponding multiples  for the
Merger, valuing  the shares  of Pinnacle  Common Stock  that would  be  received
pursuant  to  the Merger  Agreement at  $28.50 per  share of  Financial Security
Common Stock. In calculating the multiples for the Merger, Hovde used  Financial
Security's  EPS for the 12 months ended  December 31, 1995, book value per share
and tangible book value per share as of December 31, 1995, and Hovde  calculated
that Financial Security's LTM EPS, book value per share, tangible book value per
share  and tangible book premium  to core deposits were  22.3 times, 1.21 times,
1.21 times, and 5.18%, respectively.
 
    No company or  transaction used  in the above  analysis as  a comparison  is
identical  to  Financial  Security,  Pinnacle  or  the  Merger.  Accordingly, an
analysis of  the  results of  the  foregoing  is not  mathematical;  rather,  it
involves   complex  considerations  and   judgments  concerning  differences  in
financial and operating characteristics  of the companies  and other facts  that
could  affect the public trading value of  the companies to which they are being
compared.
 
    CONTRIBUTION ANALYSIS.    Hovde  prepared a  contribution  analysis  showing
percentages  of assets, deposits, common equity, and 1995 and estimated 1996 net
income contributed to  the combined company  on a pro  forma basis by  Financial
Security and Pinnacle. This analysis showed, assuming Pinnacle's stock price was
at  $32.375 per share, that  Financial Security, as of  December 31, 1995, would
contribute 25.28% of pro  forma consolidated total  assets, 21.38% of  deposits,
32.93%  of common equity, 14.46% of 1995 net income and 15.48% of estimated 1996
net income.  The  stockholders of  Financial  Security would  own  approximately
24.98%  of  the  pro  forma  common  shares  outstanding  of  Pinnacle, assuming
Pinnacle's stock price was at $32.375 per share.
 
    FINANCIAL IMPLICATIONS TO FINANCIAL  SECURITY STOCKHOLDERS.  Hovde  prepared
an  analysis of the financial implications of  the Pinnacle offer to a Financial
Security stockholder. This  analysis indicated  that on a  pro forma  equivalent
basis,  at a  $28.50 price  per share  of Financial  Security Common  Stock with
Pinnacle trading at $32.375 per share, a stockholder of Financial Security would
achieve an increase in  earnings per share of  over sixty-one percent (61%),  an
increase  in per  share dividends of  over nine  percent (9%) and  a decrease in
fully diluted book value per share of approximately twenty-one percent (21%)  in
1996 as a result of the consummation of the Merger.
 
    COMPARATIVE STOCKHOLDER RETURNS.  Hovde presented an analysis of comparative
theoretical  stockholder  returns  in  several  scenarios,  including  Financial
Security remaining independent,  Financial Security being  acquired in 2000  and
Financial  Security  being  acquired  by  Pinnacle  at  $28.50  per  share. This
analysis, which was based on the net present value of projected dividend streams
and projected  1996 common  stock  valuations (using  current  price-to-earnings
multiples),  indicated total stockholder returns  of 9.77% if Financial Security
remained independent, 12.84% for a merger in 2000 on the terms specified in  the
following  paragraph,  and 18.11%  based  on the  acceptance  of the  offer from
Pinnacle at  $28.50 per  share with  the  Pinnacle Common  Stock trading  at  an
assumed price of $32.375 per share.
 
    DISCOUNTED  CASH  FLOW ANALYSIS.   Hovde  performed  a discounted  cash flow
analysis to determine  a present value  per share of  Financial Security  Common
Stock  assuming Financial Security continued to  operate as a stand-alone entity
and was  acquired  at  a  later  date. This  present  value  was  determined  by
projecting  Financial Security's after-tax  net income for  the five years ended
December 31, 1996
 
                                       34
<PAGE>
through 2000.  Projected net  income was  determined through  consultation  with
Financial  Security's  management and  generally  included aggressive  growth in
assets (ranging from a low of three percent (3%) in 1996 and increasing to  five
percent  (5%) in 2000), as well as  progressively higher net income as a percent
of average assets (increasing from 0.72% for 1996 to 1.05% for the twelve months
ended December 31,  2000). "Terminal  value" per share  of Financial  Security's
Common  Stock was determined by  applying a price to  earnings multiple of 20.24
times against Financial Security's projected earnings at December 31, 2000.  The
present value of the terminal value was then determined using an annual discount
rate  of thirteen  percent (13%). The  above calculations resulted  in a present
value per fully diluted share of  Financial Security Common Stock of $26.90  per
share.
 
    Although  the summary  set forth  above does  not purport  to be  a complete
description of the analysis performed by Hovde, the material analysis  performed
by  Hovde  in rendering  its  opinion has  been  summarized above.  However, the
preparation of  a fairness  opinion is  not necessarily  susceptible to  partial
analysis  or  summary  description. Hovde  believes  that its  analysis  and the
summary set  forth  above must  be  considered as  a  whole and  that  selecting
portions  of its analysis,  without considering all  factors and analysis, would
create an incomplete view of the process underlying the analysis by which  Hovde
reached  its opinion. In addition, Hovde may have given various analyses more or
less weight  than other  analyses, but  no analysis  was given  materially  more
weight  than any other analysis. Also, Hovde may have deemed various assumptions
more or less probable  than other assumptions so  that the ranges of  valuations
resulting from any particular analysis described above should not be taken to be
Hovde's view of the actual value of Financial Security or the combined company.
 
    In  performing its analysis, Hovde made numerous assumptions with respect to
industry  performance,  general  business  and  economic  conditions  and  other
matters,  many  of  which  are  beyond the  control  of  Financial  Security and
Pinnacle. The  analysis performed  by  Hovde is  not necessarily  indicative  of
actual  value or actual future results, which  may be significantly more or less
favorable than suggested by such analysis. Such analysis was prepared solely  as
part  of Hovde's analysis  of the fairness  of the Merger  Consideration, from a
financial point of view, to the holders of Financial Security Common Stock.  The
analysis does not purport to be an appraisal or to reflect the prices at which a
company  might actually be sold or the  prices at which any securities may trade
at the present time  or at any time  in the future. Hovde  used in its  analysis
various  projections  of  future  performance  prepared  by  the  management  of
Financial  Security.  The  projections  are  based  on  numerous  variables  and
assumptions  which  are  inherently  unpredictable and  must  be  considered not
certain of  occurrence  as projected.  Accordingly,  actual results  could  vary
significantly  from those assumed  in the projections  and any related analysis.
Hovde's opinion does not address the  relative merits of the Merger as  compared
to  any other business combination in  which Financial Security might engage. In
addition, as described above,  Hovde's opinion to  the Financial Security  Board
was one of many factors taken into consideration by the Financial Security Board
in making its determination to approve the Merger Agreement.
 
    Based  upon the foregoing analyses  and other investigations and assumptions
set forth in its opinions, without giving  specific weight to any one factor  or
comparison,  Hovde  determined that  the Merger  Consideration  was fair  from a
financial point of view to the stockholders of Financial Security.
 
    THE SUMMARY OF THE PRESENTATION BY HOVDE TO THE FINANCIAL SECURITY BOARD  AS
SET  FORTH  ABOVE  DOES  NOT  PURPORT  TO  BE  A  COMPLETE  DESCRIPTION  OF SUCH
PRESENTATION.  THE   PREPARATION  OF   A  FAIRNESS   OPINION  INVOLVES   VARIOUS
DETERMINATIONS  AS TO  THE MOST  APPROPRIATE AND  RELEVANT METHODS  OF FINANCIAL
ANALYSES AND THE APPLICATION OF  THOSE METHODS TO THE PARTICULAR  CIRCUMSTANCES,
AND,   THEREFOR,  SUCH  AN  OPINION  IS   NOT  READILY  SUSCEPTIBLE  TO  SUMMARY
DESCRIPTION. FURTHERMORE, IN ARRIVING  AT ITS OPINION,  HOVDE DID NOT  ATTRIBUTE
ANY  PARTICULAR WEIGHT TO  ANY ANALYSIS OR  FACTOR CONSIDERED BY  IT, BUT RATHER
MADE QUALITATIVE JUDGMENTS AS TO THE SIGNIFICANCE AND RELEVANCE OF EACH ANALYSIS
AND FACTOR. ACCORDINGLY, HOVDE  BELIEVES THAT ITS ANALYSES  AND THE SUMMARY  SET
FORTH  ABOVE MUST BE  CONSIDERED AS A  WHOLE AND THAT  SELECTING PORTIONS OF ITS
 
                                       35
<PAGE>
ANALYSES,  WITHOUT  CONSIDERING  ALL  FACTORS  AND  ANALYSES,  COULD  CREATE  AN
INCOMPLETE VIEW OF THE PROCESS UNDERLYING  THE ANALYSES SET FORTH IN ITS  REPORT
TO  THE FINANCIAL  SECURITY BOARD  AND ITS  FAIRNESS OPINION.  IN PERFORMING ITS
ANALYSES, HOVDE MADE NUMEROUS ASSUMPTIONS WITH RESPECT TO INDUSTRY  PERFORMANCE,
GENERAL  BUSINESS AND ECONOMIC  CONDITIONS AND OTHER MATTERS,  MANY OF WHICH ARE
BEYOND THE CONTROL OF PINNACLE OR FINANCIAL SECURITY. THE ANALYSES PERFORMED  BY
HOVDE  ARE  NOT  NECESSARILY  INDICATIVE  OF  ACTUAL  VALUES  OR  ACTUAL  FUTURE
PERFORMANCE.
 
    Hovde will receive a fee of approximately $470,000 for services rendered  in
connection  with  advising Financial  Security  regarding the  Merger Agreement,
including the  fairness  opinion and  financial  advisory services  provided  to
Financial Security, plus reimbursement of out-of-pocket expenses. As of the date
of  this Joint Proxy  Statement/Prospectus, Hovde has  received $127,874 of such

MERGER CONSIDERATION
 
    Subject to the  terms, conditions  and procedures  set forth  in the  Merger
Agreement, each share of Financial Security Common Stock outstanding immediately
prior  to consummation of  the Merger will  be converted into  and represent the
right to receive (upon a  Financial Security stockholder's election) either  (i)
 .8803  shares  of  Pinnacle  Common Stock,  subject  to  adjustment  (the "Stock
Distribution"); (ii) $28.50 in cash (the "Cash Distribution") (provided that the
number of shares of  Financial Security Common Stock  subject to an election  to
receive cash will not exceed 45% of the outstanding shares of Financial Security
Common  Stock); or (iii) an amount in cash equal to 30% of the Cash Distribution
and shares of Pinnacle Common Stock equal to 70% of the Stock Distribution  (the
"Combined  Distribution" and together  with the Stock  Distribution and the Cash
Distribution, the "Merger  Consideration"). The Merger  Agreement provides  that
the  Exchange Ratio, shall be adjusted  to reflect any split, combination, stock
dividend or stock distribution with respect to Pinnacle Common Stock effected by
Pinnacle prior to the Effective Time.
 
    The Exchange Ratio is equal to the quotient of the agreed value of Financial
Security Common  Stock per  share, $28.50,  divided by  the per  share value  of
Pinnacle  Common Stock during a ten day trading period prior to the execution of
the Merger Agreement, $32.375.
 
    Pursuant to the Merger  Agreement, if the Pinnacle  Average Stock Price  (as
defined  below) is less than $30.00 per share but greater than $27.99 per share,
the Exchange Ratio shall be adjusted to equal the quotient of $26.00 divided  by
the  Pinnacle Average Stock Price. However,  if the Pinnacle Average Stock Price
is greater than  $35.00 per  share but  does not  exceed $37.00  per share,  the
Exchange  Ratio shall be adjusted to equal the quotient of $31.00 divided by the
Pinnacle Average Stock Price. The Pinnacle Average Stock Price is defined as the
average of the closing prices per share of Pinnacle Common Stock reported by the
Nasdaq SCM on the ten  trading days on which one  or more trades actually  occur
immediately prior to the second business day preceding the Closing Date.
 
    However,  if the Pinnacle Average Stock Price is less than $28.00 per share,
the Exchange Ratio  shall be further  adjusted to .9286  and Financial  Security
shall  have the option to  terminate the Merger Agreement  unless not later than
two days  prior to  the Closing  Date,  Pinnacle agrees  to further  adjust  the
Exchange  Ratio to equal the quotient of  $26.00 divided by the Pinnacle Average
Stock Price. Conversely, if the Pinnacle Average Stock Price exceeds $37.00  per
share,  the Exchange Ratio shall be further adjusted to .8378 and Pinnacle shall
have the option to terminate the Merger Agreement unless not later than two days
prior to  the Closing  Date, Financial  Security agrees  to further  adjust  the
Exchange  Ratio to equal the quotient of  $31.00 divided by the Pinnacle Average
Stock Price.
 
    The market price of Pinnacle  Common Stock to be  received in the Merger  is
subject  to  fluctuation  and such  fluctuation  may  result in  an  increase or
decrease in the value of the Stock Distribution or the Combined Distribution  to
be received by Financial Security stockholders in the Merger.
 
                                       36
<PAGE>
    Neither Financial Security nor Pinnacle is required to exercise its right to
terminate  the Merger  Agreement based  on the  market value  of Pinnacle Common
Stock at the Effective  Time. No decision  can be made unless  and until it  can
reasonably be anticipated that the Pinnacle Average Stock Price will trigger the
termination  rights whereupon the Boards will  make a determination based on the
relevant circumstances existing at that time.
 
    The  Cash  Distribution  is  not  subject  to  any  possible  adjustment  in
connection with the Pinnacle Average Stock Price.
 
    Pursuant  to the Merger  Agreement, options to  purchase shares of Financial
Security Common Stock shall  be converted at the  Effective Time into shares  of
Pinnacle  Common Stock. See "THE  MERGER -- Interests of  Certain Persons in the
Merger".
 
ELECTION PROCEDURES
 
    Each Financial  Security  stockholder will  have  the opportunity  to  elect
whether  to receive either the Stock  Distribution (a "Stock Election," in which
case, such holder's shares shall be  deemed to be "Stock Election Shares"),  the
Cash  Distribution (a "Cash Election," in which case, such holder's shares shall
be deemed to be "Cash Election Shares"), or a Combined Distribution (a "Combined
Election," in which case, such holder's  shares shall be deemed to be  "Combined
Election  Shares"). ENCLOSED  WITH THIS  JOINT PROXY  STATEMENT/PROSPECTUS IS AN
ELECTION FORM FOR USE BY THE  STOCKHOLDERS OF FINANCIAL SECURITY (THE  "ELECTION
FORM")  WHEREBY STOCKHOLDERS  MAY INDICATE  A STOCK  ELECTION, CASH  ELECTION OR
COMBINED ELECTION. IN ORDER FOR AN ELECTION  FORM TO BE DEEMED TO BE  EFFECTIVE,
SUCH ELECTION FORM MUST BE PROPERLY COMPLETED AND DULY EXECUTED BY THE FINANCIAL
SECURITY  STOCKHOLDERS  AND  RETURNED  TO HARRIS  TRUST  AND  SAVINGS  BANK (THE
"EXCHANGE AGENT") BY 5:00 P.M.,  CHICAGO TIME, ON THE DAY  PRIOR TO THE DATE  OF
THE FINANCIAL SECURITY MEETING OR SEPTEMBER 10, 1996 (THE "ELECTION DEADLINE").
 
    Each  separate entry on  Financial Security's list  of stockholders shall be
presumed to represent  a separate  and distinct  holder of  record of  Financial
Security  Common Stock. Shares held of record  by a bank, trust company, broker,
dealer or other recognized nominee shall be deemed to be held by a single holder
unless the nominee  advises the Exchange  Agent otherwise, in  which case,  each
beneficial  owner will be treated  as a separate holder  and, either directly or
through such nominee, may submit a  separate Election Form. Any election may  be
revoked or changed by the person submitting an Election Form or any other person
to whom the subject shares are subsequently transferred by submission of a later
dated  Election  Form  properly completed  and  duly executed,  received  by the
Exchange Agent by the Election Deadline.
 
    Any stockholder who fails to deliver a properly completed and duly  executed
Election  Form to the Exchange Agent by the Election Deadline shall be deemed to
have made no  election (a  "No Election," in  which case,  such holder's  shares
shall  be deemed to be "No Election Shares"). No Election Shares will be treated
as Stock Election Shares for purposes of determining the type and amount of  the
Merger Consideration payable pursuant to the Merger.
 
    In  the event the number of shares of Pinnacle Common Stock distributable in
respect of the Stock  Election Shares and the  Combined Election Shares is  less
than fifty-five percent (55%) of the Merger Consideration or such greater amount
as  required by the Minimum Share Notice  (as defined below), the Exchange Agent
will reallocate the  Merger Consideration  payable to  each holder  of the  Cash
Election Shares pro rata (based upon the number of Cash Election Shares owned by
such  holder as compared with the total  number of Cash Election Shares owned by
all holders) such that holders of  Cash Election Shares will receive the  number
of  shares of Pinnacle Common Stock which in the aggregate will equal fifty-five
percent (55%) of the Merger Consideration or the amount set forth in the Minimum
Share Notice. The balance of the Merger  Consideration, if any, will be paid  in
cash. The amount of cash will be determined by computing the value of the Merger
Consideration  which each  such holder  is entitled  to receive  pursuant to the
Merger by multiplying the  number of shares of  Financial Security Common  Stock
owned  at the Effective Time by the  per share value of the Merger Consideration
and subtracting from the amount described above  the value of the shares of  the
 
                                       37
<PAGE>
Pinnacle  Common Stock to be issued. The Minimum Share Notice is the notice that
Muldoon, Murphy and  Faucette, counsel  to Financial  Security ("Muldoon")  will
issue  to the Exchange  Agent if the  total number of  shares of Pinnacle Common
Stock issuable to  all holders of  Stock Election Shares  and Combined  Election
Shares  is insufficient to allow Muldoon to issue its opinion concerning the tax
free nature of the Merger.
 
SURRENDER OF CERTIFICATES
 
    Within ten  (10)  days after  the  Effective  Time, the  Exchange  Agent  is
required  to mail to each holder of  record of Financial Security Common Stock a
letter of transmittal  and instructions for  use in effecting  the surrender  of
such holder's Financial Security Common Stock certificates.
 
    FINANCIAL  SECURITY STOCKHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES
UNTIL THEY RECEIVE  THE LETTER  OF TRANSMITTAL  FORM AND  INSTRUCTIONS FROM  THE
EXCHANGE AGENT.
 
    Upon  surrender  to  the  Exchange  Agent of  one  or  more  certificates of
Financial Security Common Stock,  together with a  properly completed letter  of
transmittal,  the Exchange Agent will  cause to be issued  and mailed the Merger
Consideration after receipt of all required documentation pursuant to the Merger
Agreement. The surrendered certificates of Financial Security Common Stock  will
thereupon  be canceled. A Pinnacle  Common Stock certificate may  be issued in a
name other than  the name  in which  the surrendered  Financial Security  Common
Stock  certificate  is  registered  only  if  a  certificate  representing  such
Financial Security Common Stock is presented to the Exchange Agent,  accompanied
by  all documents required to evidence and effect a transfer to the new name and
by evidence that any applicable stock transfer taxes have been paid.
 
    No dividends or other distributions  declared after the Effective Time  with
respect  to Pinnacle Common Stock payable to the holders of record thereof after
the Effective Time shall be paid to the holder of any unsurrendered  certificate
of  Financial  Security Common  Stock  until such  holder  of record  shall have
surrendered such Financial Security Common Stock certificate in good and  proper
form.  After the subsequent surrender and  exchange of a certificate, the holder
thereof shall  be  entitled to  receive  any such  dividends  or  distributions,
without  interest  thereon, which  theretofore  became payable  with  respect to
Pinnacle Common Stock represented  by such certificate.  Any shares of  Pinnacle
Common  Stock or cash in the exchange  fund maintained by the Exchange Agent and
not exchanged for Financial Security  Common Stock certificates within  eighteen
months  after the  Effective Time  shall be  returned by  the Exchange  Agent to
Pinnacle which shall thereafter act as  exchange agent subject to the rights  of
holders of unsurrendered Pinnacle Common Stock certificates.
 
FRACTIONAL SHARES
 
    No  certificates or scrip representing  fractional shares of Pinnacle Common
Stock  will  be  issued  upon   the  surrender  for  exchange  of   certificates
representing  Financial Security  Common Stock,  no dividend  or distribution of
Pinnacle will  relate  to  any  fractional shares,  and  such  fractional  share
interests  will not  entitle the  owner thereof to  vote or  to any  rights of a
Pinnacle stockholder. Each Financial Security stockholder who would be  entitled
to a fractional share of Pinnacle Common Stock in the Merger will receive a cash
payment  (without interest) determined  by multiplying (i)  the Pinnacle Average
Stock Price by  (ii) the  fractional share interest  to which  the holder  would
otherwise be entitled pursuant to the terms of the Merger Agreement.
 
EFFECTIVE TIME AND CLOSING DATE
 
    The  Effective Time of the Merger will be the time and date specified in the
articles of merger  to be  filed with  the Secretary of  State of  the State  of
Illinois  and the certificate of merger to  be filed with the Secretary of State
of the State of Delaware. Such filing  will occur only after the receipt of  all
requisite  regulatory approvals and the approval  of the Merger by the requisite
votes of Pinnacle's  and Financial  Security's respective  stockholders and  the
satisfaction  or waiver of all other conditions  to the Merger. The Closing Date
of the Merger will be within thirty  (30) business days after the expiration  of
all
 
                                       38
<PAGE>
applicable   waiting  periods  in  connection  with  approvals  of  governmental
authorities and  all conditions  to the  consummation of  the Merger  have  been
satisfied  or waived in accordance with the terms of the Merger Agreement, or at
another time agreed to in writing by Pinnacle and Financial Security.
 
    Subject  to  obtaining  all  requisite  approvals,  Pinnacle  and  Financial
Security  currently anticipate that the Merger will be consummated in September,
1996. The Merger Agreement provides that  either party may terminate the  Merger
Agreement  if the Merger is  not consummated by March  31, 1997, but the parties
can extend that date by mutual consent to  a date to be determined by them.  See
"-- Waiver and Amendment" and "-- Termination and Termination Fee."
 
REPRESENTATIONS AND WARRANTIES
 
    In  the Merger Agreement,  each of Pinnacle and  Financial Security has made
certain customary  representations  and  warranties  relating  to,  among  other
things,  the parties' respective organization,  authority relative to the Merger

to the satisfaction by Financial Security or waiver by Pinnacle of the following
conditions: (i)  Financial Security  shall  have performed  or complied  in  all
material  respects  with all  covenants and  agreements  required by  the Merger

REGULATORY APPROVALS
 
    The Merger is subject to prior approval by the OTS under HOLA. Section 10(e)
of HOLA requires that the application be evaluated by taking into  consideration
the  financial and managerial resources and the future prospects of Pinnacle and
Financial Security and their respective  subsidiaries, the risks to the  federal
deposit  insurance funds and the convenience  and needs of relevant communities.
In
 
                                       41
<PAGE>
addition, Section 10(e)(2)  of HOLA requires  that the Director  of the OTS  not
approve  any proposed acquisition (i) which would result in a monopoly, or which
would be in  furtherance of any  combination or conspiracy  to monopolize or  to
attempt  to monopolize the savings  and loan business in  any part of the United
States, or (ii)  the effect  of which,  in any section  of the  country, may  be
substantially  to lessen competition, or tend to  create a monopoly, or which in
any other  manner would  be in  restraint of  trade, unless  it finds  that  the
anti-competitive  effects of the proposed  acquisition are clearly outweighed in
the public interest  by the probable  effect of the  acquisition in meeting  the
convenience and needs of the communities to be served. The OTS has the authority
to deny an application if it concludes that the combined organization would have
an  inadequate  capital  position. Furthermore,  the  OTS must  also  assess the
records of the  depository institution  subsidiaries of both  parties under  the
Community  Reinvestment Act  of 1977, as  amended (the "CRA").  The CRA requires
that the OTS analyze, and take into account when evaluating an application, each
institution's record  of meeting  the  credit needs  of its  local  communities,
including low- and moderate-income neighborhoods, consistent with safe and sound
operation.  The OTS may also request  additional information. The OTS procedures
provide for publication of notice of  the application and public comment  and/or
requests  for agency  hearings. Pinnacle filed  its application with  the OTS on
June 12, 1996, and the application is currently pending.
 
    In addition, the Merger is subject to prior approval of the Federal  Reserve
pursuant  to Section  4 of  the BHC Act.  Under Section225.23(a)  of the Federal
Reserve's Regulation  Y, Pinnacle  is required  to give  notice to  the  Federal
Reserve  requesting prior approval  of Pinnacle's proposal  to acquire Financial
Security. The Federal Reserve's procedures involve public notice of the  receipt
of  the notice application and an opportunity for public comment and/or requests
for agency hearings on  the application. In evaluating  a notice application  of
this  nature, the Federal  Reserve considers, among  other things, the financial
and managerial resources of the notificant and its subsidiaries and the  company
to  be acquired and the  effect of the proposed  transaction on those resources.
Generally, the Federal Reserve considers whether the proposed transaction by the
notificant can reasonably be expected to produce benefits to the public (such as
greater  convenience,  increased  competition  and  gains  in  efficiency)  that
outweigh any possible adverse effects (such as undue concentration of resources,
decreased  or  unfair competition,  conflicts of  interest, and  unsound banking
practices). The Federal Reserve also considers  the CRA records of the  relevant
depository  institution's subsidiaries of both  parties. The Federal Reserve may
also deny  the  notice  application  if the  notificant  fails  to  provide  all
information  requested  by  the  Federal  Reserve.  Pinnacle  filed  its  notice
application on July 1, 1996, and the notice is currently pending.
 
    The Merger cannot proceed  in the absence of  all regulatory approvals.  See
"--  Conditions to the  Merger." Pinnacle and Financial  Security have agreed to
take all reasonable actions  necessary to obtain approvals  and comply with  the
requirements  of  the  OTS  and the  Federal  Reserve.  Although  no significant
difficulties are anticipated in obtaining  regulatory approval, there can be  no
assurance  that such approvals will be obtained or that there will not be delays
in processing the applications.
 
    Pinnacle and  Financial Security  are not  aware of  any other  governmental
approvals  or actions that are required for consummation of the Merger except as
described above.  Should  any  other  approval or  action  be  required,  it  is
presently  contemplated that such approval or  action would be sought. There can
be no assurance that any such approval or action, if needed, could be  obtained,
and  if such approval or  actions are obtained, there can  be no assurance as to
the timing thereof.
 
WAIVER AND AMENDMENT
 
    Prior to the  Effective Time of  the Merger and  subject to applicable  law,
Pinnacle  and  Financial Security  may extend  the time  for performance  of any
obligations of the other under the  Merger Agreement, waive any inaccuracies  in
the  representations  and  warranties  of  the  other  contained  in  the Merger
Agreement and waive compliance  with any agreements or  conditions of the  other
contained  in  the Merger  Agreement. Subject  to  applicable law,  Pinnacle and
Financial Security may  also amend the  Merger Agreement at  any time before  or
after approval of the Merger Agreement by the
 
                                       42
<PAGE>
stockholders  of Pinnacle  and Financial  Security, provided  that any amendment
effected after  approval of  such  stockholders may  not adversely  affect  such
stockholders,  including by the alteration  of the amount or  kind of the Merger
Consideration.
 
NO SOLICITATION
 
    Financial Security has agreed that neither it and its subsidiaries, nor  any
of  their respective officers, directors,  employees, representatives, agents or
affiliates (including, without limitation,  any investment banker, attorney,  or
accountant  retained by  Financial Security or  any of  its subsidiaries), will,
directly or indirectly, initiate, solicit  or knowingly encourage any  inquiries
or  the  making of  any proposal  or offer  (including, without  limitation, any
proposal or  offer to  stockholders of  Financial Security)  with respect  to  a
merger,  consolidation or similar  transaction involving any  purchase of all or
any significant portion of assets or any equity securities of Financial Security
or any  of its  subsidiaries  (any such  proposal, an  "Acquisition  Proposal").
Pursuant  to  the  Merger  Agreement, Financial  Security  will  notify Pinnacle
promptly of the relevant details relating  to all inquiries and proposals  which
it  may  receive  relating  to  any  Acquisition  Proposal.  Notwithstanding the
foregoing, Financial Security may engage in negotiations concerning, or  provide
any  confidential  information or  data to,  or have  any discussions  with, any
person or entity related to an  Acquisition Proposal if, the Financial  Security
Board of Directors, after consultation with outside legal counsel, determines in
good  faith that such  action is necessary  for the Financial  Security Board of
Directors to comply with its  fiduciary duties to stockholders under  applicable
law  and promptly notifies Pinnacle of any inquiries, proposals, negotiations or
discussions in respect of any such Acquisition Proposal together with details as
to the identity of  the persons making such  inquiry, proposals or seeking  such
negotiations or discussions and the terms and conditions thereof.
 
TERMINATION AND TERMINATION FEE
 
    The  Merger Agreement may be  terminated at any time  prior to the Effective
Time of  the  Merger, by:  (i)  the mutual  consent  of Pinnacle  and  Financial
Security,  as  expressed  by  a  majority vote  of  their  respective  Boards of
Directors; (ii)  either Pinnacle  or Financial  Security as  expressed by  their
respective  Boards of  Directors, if  the Merger has  not occurred  by March 31,
1997, provided that the failure of the Merger to so occur will not be due to the
failure to perform  or comply with  any covenant or  agreement contained in  the
Merger  Agreement by  the party seeking  to terminate; (iii)  either Pinnacle or
Financial Security  (provided  the party  seeking  termination is  not  then  in
material  breach of  any representation,  warranty, covenant  or other agreement
contained in the Merger  Agreement) if the other  party to the Merger  Agreement
has  (A) failed to perform or comply with any covenant or agreement contained in
the Merger Agreement which failure or non-compliance is material in the  context
of  the  transactions contemplated  by  the Merger  Agreement,  or (B)  made any
inaccuracies,  omissions  or  breaches   in  the  representations,   warranties,
covenants  or agreements contained in the  Merger Agreement the circumstances of
which either  individually or  in the  aggregate have,  or reasonably  could  be
expected  to have a material  adverse effect on the  other party, which have not
been cured within 30 days after the date on which written notice of such  breach
is  given to the party committing such breach; (iv) either Financial Security or
Pinnacle by written notice to  the other party if  (A) any approval, consent  or
waiver of a governmental authority required to permit consummation of the Merger
shall   have  been  denied;  (B)  any  governmental  authority  issues  a  final
unappealable order  enjoining  or  otherwise  prohibiting  consummation  of  the
Merger; or (C) the holders of Financial Security Common Stock or Pinnacle Common
Stock  fail to approve and  adopt the Merger Agreement;  provided no party shall
have the right to terminate the Merger Agreement pursuant to this clause (iv) if
the occurrence of item (A), (B) or (C) is attributable to the party's failure to
perform or  observe  the  covenants  and agreements  set  forth  in  the  Merger
Agreement;  (v) Pinnacle, if  there has occurred an  event, condition, change or
occurrence which, individually or in the aggregate, has had or could  reasonably
be  expected to result in  a material adverse effect  on Financial Security, and
Financial Security  shall not  have remedied  such event,  condition, change  or
occurrence  within 30  days from  notice of  termination; (vi)  Pinnacle, if the
Pinnacle Average Stock  Price exceeds  $37.00 per share  and Financial  Security
does  not agree to decrease  the Exchange Ratio to  equal the quotient of $31.00
 
                                       43
<PAGE>
divided by the Pinnacle  Average Stock Price; (vii)  Financial Security, if  the
Pinnacle Average Stock Price is less than $28.00 per share and Pinnacle does not
agree  to increase the Exchange Ratio to equal the quotient of $26.00 divided by
the Pinnacle Average Stock Price; and (viii) Pinnacle, if five days prior to the
Closing Date, the value of certain office equipment leases which were  purchased
by  Security Federal from Bennett Funding  Group, Inc. (the "Bennett Portfolio")
has decreased by an amount in excess of $375,000 before any related tax  savings
and  Financial Security  does not agree  two days  prior to the  Closing Date to
reduce the consideration payable pursuant to the Merger Agreement by the  amount
of  the loss in the Bennett Portfolio in excess of $375,000 less any tax savings
attributable  to  the  loss.  See  "BUSINESS  OF  FINANCIAL  SECURITY  --   Loan
Portfolio."
 
    If,  prior to October 22, 1997, the  Merger has not been consummated and (i)
any person other than  Pinnacle acquires beneficial  ownership of fifty  percent
(50%)  or more  of the  then outstanding  Financial Security  Common Stock; (ii)
Financial Security, without Pinnacle's prior written consent, (A) enters into an
agreement to engage  in an  Acquisition Transaction  (as defined  below) with  a
party  other than Pinnacle  or (B) the Financial  Security Board recommends that
the  stockholders  of  Financial  Security  approve  or  accept  an  Acquisition
Transaction  with a third party, or  (iii) if a bona fide  proposal is made by a
third party to engage in an  Acquisition Transaction and after such proposal  is
made  (A)  Financial Security  breaches  the Merger  Agreement  which materially
impairs Financial Security's ability  to consummate the  Merger and such  breach
entitles  Pinnacle to terminate the Merger Agreement; (B) the Financial Security
Meeting is  not held  or is  canceled prior  to the  termination of  the  Merger
Agreement  for reasons other  than Pinnacle's fault  or (C) Financial Security's
Board of Directors withdraws or modifies its recommendation in a manner  adverse
to  Pinnacle, then, in such case, Financial Security is required to pay Pinnacle
a termination fee  of $600,000 following  such termination. Notwithstanding  the
foregoing,  Financial Security will not be  obligated to pay the termination fee
if Financial  Security validly  terminates the  Merger Agreement  under  certain
conditions.  For  purposes of  the  Merger Agreement,  "Acquisition Transaction"
means a  (x) merger  or  consolidation, or  any similar  transaction,  involving
Financial  Security,  (y)  purchase,  lease  or  other  acquisition  of  all  or
substantially all of the assets of  Financial Security or (z) purchase or  other
acquisition  (including  by  way  of merger,  consolidation,  share  exchange or
otherwise) of securities representing fifty percent (50%) or more of the  voting
power  of Financial Security;  provided the term  "Acquisition Transaction" does
not include  any  internal  merger or  consolidation  involving  only  Financial
Security and/or its subsidiaries.
 
    In  the event of the termination and abandonment of the Merger Agreement and
the Merger pursuant to  the above, the Merger  Agreement, other than  provisions
relating  to confidentiality of  information obtained by the  parties and to the
payment of expenses relating to the Merger, shall become void and of no  effect,
without  any liability on  the part of  any party or  its directors or officers,
provided that nothing contained  in the Merger Agreement  will serve to  relieve
any party from liability for a willful breach of the Merger Agreement.
 
ACCOUNTING TREATMENT
 
    The Merger is to be accounted for as a purchase in accordance with generally
accepted  accounting  principles  as  outlined  in  Accounting  Principles Board
Opinion  No.  16,  "Business  Combinations."   Under  the  purchase  method   of
accounting,  the excess  of purchase  price paid over  the fair  market value of
assets and liabilities acquired  (goodwill) is recorded  as an intangible  asset
and  such  asset is  amortized as  an expense  over the  period estimated  to be
benefitted. Under  the purchase  method of  accounting, the  reported income  of
Pinnacle will include the results of operations of Financial Security only as of
and from the Effective Time.
 
EXPENSES
 
    All  expenses  incurred  in connection  with  the Merger  Agreement  and the
transactions contemplated thereby  are to be  paid by the  party incurring  such
expenses, except Pinnacle and Financial
 
                                       44
<PAGE>
Security  shall each pay one-half  of the costs incurred  in connection with the
printing and  mailing  of  the  Registration  Statement  and  this  Joint  Proxy
Statement/Prospectus.  All fees payable  to Hovde in  connection with the Merger
will be paid by Financial Security.
 
RESALES OF PINNACLE COMMON STOCK BY AFFILIATES
 
    The shares of  Pinnacle Common  Stock to  be issued  in the  Merger will  be
registered  under the Securities  Act and will be  freely transferable under the
Securities Act, except  for shares issued  pursuant to the  terms of the  Merger
Agreement  to any holder of Financial Security  Common Stock or to any holder of
Financial Security  stock options  who may  be deemed  to be  an "affiliate"  of
Financial Security for purposes of Rule 145 under the Securities Act. Affiliates
may  not sell their shares of Pinnacle  Common Stock acquired in connection with
the Merger  except pursuant  to an  effective registration  statement under  the
Securities  Act covering such shares  or in compliance with  Rule 145 or another
applicable exemption from the registration requirements of the Securities Act.
 
    Financial Security has agreed in the Merger Agreement to use its  reasonable
efforts  to cause each director,  executive officer and other  person who may be
deemed an affiliate  (for purposes of  Rule 145)  of such party  to execute  and
deliver  a written agreement  providing that such person  will not sell, pledge,
transfer or  otherwise dispose  of the  shares of  Pinnacle Common  Stock to  be
received  by such  person upon consummation  of the Merger  except in compliance
with applicable provisions of the Securities Act.
 
    This Joint Proxy Statement/Prospectus cannot be used for resales of Pinnacle
Common Stock received by any person who may be deemed an "affiliate" of Pinnacle
or Financial Security.
 
MANAGEMENT AND OPERATIONS AFTER THE MERGER
 
    Pursuant to  the  Merger  Agreement, the  current  directors  and  executive
officers  of  Pinnacle  will be  the  directors  and executive  officers  of the
surviving corporation in the Merger.  Following the consummation of the  Merger,
Security  Federal  will become  a wholly  owned subsidiary  of Pinnacle.  In the
future,  Pinnacle  may  merge  Security   Federal  into  Pinnacle  Bank.   After
consummation  of the Merger, Security Federal  will conduct its business largely
as presently conducted.
 
    All persons  who are  employees of  Financial Security  or Security  Federal
immediately  prior to the Effective Time shall, after the Effective Time, become
employees of Pinnacle, one of the Pinnacle Subsidiary Banks or Security Federal.
Pinnacle has agreed to use its  best efforts to reasonably identify within  (30)
thirty  days  of the  Effective  Time the  employees  of Financial  Security and
Security Federal  to  whom  Pinnacle  intends  to  offer  employment;  provided,
however,  that Pinnacle  shall not  have any duty  or obligation  to continue to
employ any former employees of Financial Security or Security Federal beyond the
Effective Time.
 
    Pinnacle will  pay a  severance benefit  to each  person, other  than  those
persons  who have  entered into written  agreements with  Financial Security and
Security Federal and  that are  identified in the  Merger Agreement,  who is  an
employee  of Financial Security or Security Federal at the Effective Time of the
Merger and who is terminated without cause within twelve months of the Effective
Time. Terminated  employees  shall receive  any  benefit provided  to  similarly
situated  employees of Pinnacle upon termination  including four weeks of salary
plus one additional week of  salary for every year of  credited service up to  a
maximum  of sixteen  weeks. For purposes  of the foregoing,  former employees of
Financial Security and  Security Federal  will receive credit  for service  with
Financial  Security or Security Federal to the  same extent and in the manner as
if such employees had been employed by Pinnacle.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    Certain members of  Financial Security's  management may be  deemed to  have
interests  in  the Merger  in  addition to  their  interests as  stockholders of
Financial Security generally. In each case, the Board of Directors of  Financial
Security  was aware  of their  potential interests,  and considered  them, among
other  matters,  in  approving  the   Merger  Agreement  and  the   transactions
contemplated thereby.
 
                                       45
<PAGE>
    INDEMNIFICATION.    Pursuant to  the Merger  Agreement, Pinnacle  has agreed
that, for a period of six years following the Effective Time (or until the final
disposition of any claims made during  that time period), it will indemnity  the
present  and  former  directors  and  officers  of  Financial  Security  or  its
subsidiaries against  any costs  or  expenses (including  reasonable  attorneys'
fees),  judgments,  fines, losses,  claims, damages  or liabilities  incurred in
connection with any  claim, action, suit,  proceeding or investigation,  whether
civil,  criminal,  administrative  or  investigative,  and  whether  or  not the
indemnified party  is  a party  thereto,  arising  out of  matters  existing  or
occurring  at  or  prior  to  the  Effective  Time  (including  the transactions
contemplated by the Merger Agreement), whether asserted or claimed prior to,  at
or  after the Effective Time, to the fullest extent permitted under Delaware law
or, if greater, as provided in Financial Security's Certificate of Incorporation
in effect  on  the date  of  the Merger  Agreement.  In addition,  Pinnacle  and
Financial Security have agreed that Financial Security shall obtain officers and
directors  liability insurance at Financial  Security's current levels and scope
for all  persons  who are  officers  and  directors of  Financial  Security  and
Security  Federal for a period  of six years after  the Effective Time, provided
the aggregate cost  of such insurance  shall not exceed  $50,000. In  connection
with  the execution of the Merger Agreement,  each of the directors of Financial
Security and  its subsidiaries  stated that  they were  unaware of  any acts  or
omissions  in his  or her  capacity as  a director  and/or officer  of Financial
Security  or  its   subsidiaries  which  would   give  rise  to   a  claim   for
indemnification from Financial Security or its subsidiaries which are reasonably
likely  to  have  a  material  adverse  effect  on  Financial  Security  or  its
subsidiaries.
 
    EMPLOYMENT  AGREEMENTS.    Financial  Security  and  Security  Federal  have
employment  agreements with Ivan F. Kovac, Daniel K. Augustine, Patrick Hunt and
Frank Swiderski.
 
    Pursuant  to  the  employment  agreements,  if  termination,  voluntary   or
involuntary,  results from a change in control of Financial Security or Security
Federal, the executive,  or in  the event of  death, his  beneficiary, would  be
entitled  to a  severance payment equal  to the  greater of (i)  three times the
executive's average  annual  compensation including  any  commissions,  bonuses,
benefit  plan  contributions, fees  and severance  payments  for the  past three
years, or  (ii)  the  payments  otherwise  remaining  under  the  terms  of  the
employment agreement. Financial Security or Security Federal would also continue
the  executive's life, health, accident, dental  and disability coverage for the
remaining unexpired  terms  of the  agreements.  In the  event  of a  change  in
control,  the severance  payment to  the executive  will be  limited to  one (1)
dollar less than the triggering amount as described in Section 280G of the Code,
the triggering amount being  equal to approximately three  times the average  of
the  past five years of taxable income  received by the executive from Financial
Security or Security Federal, but only  if such limiting amount is greater  than
the amount of the severance payment set out in the employment agreement less any
applicable excise tax required on such severance payment under Sections 280G and
4999  of the  Code. The Merger  would constitute  a change in  control under the
agreements.
 
    Pursuant to the Merger  Agreement, Pinnacle will  honor, in accordance  with
their terms, all existing employment agreements unless otherwise mutually agreed
to  by Pinnacle  and the  individual executive  officer. In  connection with the
execution of the Merger Agreement, Messrs. Kovac, Augustine, Hunt and  Swiderski
entered  into  letters of  understanding providing  for  the amendment  of their
respective employment agreements limiting  any change in  control payment to  an
amount  equal to one dollar less than the amount which would trigger 280G of the
Code. As a result, lump sum  severance payments of $414,801, $484,557,  $164,430
and  $273,924  will be  paid to  Messrs. Kovac,  Augustine, Hunt  and Swiderski,
respectively. If the Merger is not  consummated prior to December 31, 1996,  the
payment  will be  subject to adjustment.  Pinnacle may  negotiate new employment
agreements with certain of the executive officers.
 
    Messrs. Augustine,  Hunt  and  Swiderski  also  may  enter  into  consulting
agreements  with  Pinnacle  in  the amount  of  $204,000,  $36,200  and $25,000,
respectively. Pinnacle believes that the  continued service of these  executives
will  assist  in fully  preserving the  ongoing  business operation  of Security
Federal.
 
                                       46
<PAGE>
    In addition, Financial Security and Security Federal have change in  control
agreements  with  Messrs.  Preissner,  Yamtich and  Sylvestrak.  Each  change in
control agreement  provides that  following  a change  in control  of  Financial
Security  or Security Federal, if the executive's employment is terminated or if
the executive terminates his employment  following his demotion, loss of  title,
office  or significant authority, a reduction in his compensation, or relocation
of his principal place of employment, the executive would be entitled to receive
a payment  equal  to three  times  his  then current  annual  salary.  Financial
Security and Security Federal would also continue the executive's life, medical,
dental  and disability  coverage for a  period of thirty-six  months following a
change in control. As  a result, if the  executives are terminated, a  severance
payment  of $201,000, $210,900 and $222,300  would be paid to Messrs. Preissner,
Yamtich, and Sylvestrak, respectively. The  Merger would constitute a change  in
control under the agreements.
 
    Pursuant  to the Merger  Agreement, Pinnacle will  honor, in accordance with
their terms, all existing change in control contracts unless otherwise  mutually
agreed  to by  Pinnacle and the  individual officer. Pinnacle  may negotiate new
change in control agreements with certain officers.
 
    STOCK OPTIONS.  Each option to purchase shares of Financial Security  Common
Stock  shall be converted  at the Effective  Time into such  number of shares of
Pinnacle Common Stock as are equal in value to (i) the product of (A) the number
of shares of Financial Security Common Stock subject to Financial Security stock
options, (B) the Exchange Ratio and  (C) the Pinnacle Average Stock Price,  less
(ii) the aggregate exercise price for the number of shares of Financial Security
Common  Stock subject to Financial Security  stock options. No fractional shares
shall be issued by Pinnacle with regard to Financial Security stock options.
 
    EFFECT ON  FINANCIAL SECURITY  EMPLOYEE BENEFITS  PLANS.   All employees  of
Financial Security immediately prior to the Effective Time of the Merger who are
employed  by  Pinnacle  or any  of  the Pinnacle  Bank  Subsidiaries immediately
following the  Effective  Time  of  the  Merger  ("Transferred  Employees")  may
participate  in  pension  and welfare  plans  maintained by  Pinnacle  after the
Effective Time to  which they  are eligible based  on their  length of  service,
compensation, job classification, and position, including, where applicable, any
incentive  compensation plan. Pinnacle  shall provide to  employees of Financial
Security and  Security Federal  who  become employees  of Pinnacle,  a  Pinnacle
Subsidiary  Bank or Security Federal, employee  benefits on terms and conditions
which, when taken as a  whole, are substantially the  same as those provided  by
Pinnacle  or the Pinnacle Subsidiary Banks  to their similarly situated officers
and employees. Except  as otherwise  prohibited by  law, Transferred  Employees'
service  with Financial Security will be recognized as service with Pinnacle for
purposes of eligibility  to participate  and vest,  if applicable  (but not  for
purposes of benefit accrual) under Pinnacle's benefit plans.
 
    Pinnacle  will assume and honor in  accordance with their terms all existing
written  employment,  severance,  change  in  control  and  other   compensation
agreements,  including the Supplemental  Employee Stock Retirement  Plan and the
Supplemental Retirement  Agreement between  Financial Security  and any  of  its
subsidiaries, and any officer, director or employee of Financial Security or any
of  its subsidiaries. Pursuant to the Merger Agreement, Financial Security shall
(i) make a  sufficient contribution  to the  Security Federal  Savings and  Loan
Association  Retirement Plan (the "Security Federal  Pension") to fully fund the
Security Federal Pension  on a  termination basis; (ii)  terminate the  Security
Federal  Pension  on or  prior to  the  Effective Time  and (iii)  terminate the
Security Federal Savings and Loan Association Employee Stock Ownership Plan (the
"Security Federal ESOP")  and the Security  Federal ESOP loan  shall be  repaid;
provided,  however, a final determination letter  shall be obtained from the IRS
before termination of the plans.
 
    In addition, all grants and awards  under the Financial Security option  and
award  plans will become fully vested upon  the consummation of the Merger. With
respect to any  outstanding share  awards, employees will  be able  to elect  to
receive either the Stock Election, Cash Election or Combination Election.
 
                                       47
<PAGE>
    OTHER  AGREEMENTS.  Mr. Robert Genetski,  a member of the Financial Security
Board of Directors  and the Director  of Research and  Asset Management  Chicago
Capitol,  Inc., has  provided economic forecasting,  commentary and consultation
for Pinnacle on an as-needed basis since July 1990. Mr. Genetski receives $1,000
per quarter  from Pinnacle  in  consideration of  such services.  The  Financial
Security  Board  of  Directors was  aware  of Mr.  Genetski's  relationship with
Pinnacle throughout the negotiation of the Merger Agreement.
 
CERTAIN TAX CONSEQUENCES OF THE MERGER
 
    It is a condition  to the obligation of  Pinnacle and Financial Security  to
consummate  the Merger that Pinnacle and  Financial Security shall have received
an opinion of  Muldoon, counsel to  Financial Security, to  the effect that  the
Merger  will  be  treated as  a  reorganization  within the  meaning  of Section
368(a)of the Code. Assuming the  Merger is so treated, no  gain or loss will  be
recognized  for federal income tax purposes by Pinnacle or Financial Security as
a result of the Merger or by  a holder of Financial Security Common Stock,  upon
receipt solely of Pinnacle Common Stock pursuant to the Merger. Cash received by
a  holder of Financial Security Common Stock  (i) in consideration of his or her
shares of Financial Security Common Stock  pursuant to a Cash Distribution or  a
Combined  Distribution,  or  (ii) in  lieu  of  a fractional  share  interest in
Pinnacle Common Stock will be treated as received in exchange for such Financial
Security Common  Stock or  such  fractional share  interest in  Pinnacle  Common
Stock,  as the  case may  be, and gain  or loss  will be  recognized for federal
income tax  purposes, measured  by the  difference between  the amount  of  cash
received  and the adjusted tax  basis of the share  of Financial Security Common
Stock surrendered or portion thereof allocable to a fractional share interest in
Pinnacle, as the case may be. Such gain  or loss should be capital gain or  loss
if such share of Financial Security Common Stock or fractional share interest in
Pinnacle  is held as a  capital asset by such  stockholder and will be long-term
capital gain or  loss if  held for  more than one  year at  the Effective  Time.
However, if the cash payment has the effect of a distribution of a dividend, the
amount  of taxable  income recognized  generally will  equal the  amount of cash
received; such income generally will be taxable  as a dividend; and no loss  (or
other  recovery  of such  stockholder's tax  basis for  the shares  of Financial
Security Common Stock surrendered in the exchange) generally will be  recognized
by  such stockholder. The determination of whether a cash payment has the effect
of a distribution  of a dividend  will be  made pursuant to  the provisions  and
limitations  of Section  302 of the  Code, taking into  account the constructive
stock ownership rules of Section 318 of the Code.
 
    IMPACT OF SECTION  302 OF THE  CODE.   The determination of  whether a  cash
payment  has the effect of the distribution of a dividend generally will be made
in accordance with the provisions of Section 302 of the Code. A cash payment  to
a  Financial Security stockholder will  be considered not to  have the effect of
the distribution  of  a  dividend  under  Section  302  of  the  Code  and  such
stockholder  will recognize capital  gain or loss  only if the  cash payment (i)
results in a "complete redemption" of such stockholder's actual and constructive
stock interest, (ii) results in a "substantially disproportionate" reduction  in
such  stockholder's actual  and constructive  stock interest,  or (iii)  is "not
essentially equivalent to a dividend."
 
    A cash payment  will result in  a "complete redemption"  of a  stockholder's
stock  interest and such stockholder will recognize capital gain or loss if such
stockholder does not actually or constructively own any stock after the  receipt
of  the cash  payment. A  reduction in  a stockholder's  stock interest  will be
"substantially disproportionate"  and such  stockholder will  recognize  capital
gain  or  loss  if  (i)  the  percentage  of  outstanding  shares  actually  and
constructively owned by such stockholder after  the receipt of the cash  payment
is  less  than eighty  percent  (80%) of  the  percentage of  outstanding shares
actually and constructively owned by  such stockholder immediately prior to  the
receipt  of the cash  payment. A cash  payment will qualify  as "not essentially
equivalent to a dividend" and a stockholder will recognize capital gain or  loss
if  it results in a meaningful reduction in the percentage of outstanding shares
actually and constructively owned by  such stockholder. No specific tests  apply
to  determine  whether  a reduction  in  a stockholder's  ownership  interest is
meaningful; rather, such determination will be  made based on all the facts  and
circumstances  applicable  to such  Financial  Security stockholder.  No general
guidelines dictating the appropriate  interpretation of facts and  circumstances
have
 
                                       48
<PAGE>
been  announced by  the courts  or issued by  the Internal  Revenue Service (the
"Service"). However, the Service has indicated  in Revenue Ruling 76-385 that  a
minority  stockholder (I.E.,  a holder who  exercises no  control over corporate
affairs and whose  proportionate stock interest  is minimal in  relation to  the
number  of shares outstanding) generally is  treated as having had a "meaningful
reduction" in  interest if  a  cash payment  reduces  such holder's  actual  and
constructive stock ownership to any extent.
 
    With  regard to Financial Security  stockholders who receive Pinnacle Common
Stock and cash in the  Merger, the determination of  whether a cash payment  has
the  effect of  a distribution of  a dividend will  be made as  if the Financial
Security Common  Stock  exchanged  for  cash in  the  Merger  had  instead  been
exchanged in the Merger for shares of Pinnacle Common Stock followed immediately
by  a redemption  of such  shares by  Pinnacle for  the cash  payment (a "deemed
Pinnacle redemption"). Under this analysis, the determination of whether a  cash
payment  qualifies as a substantially  disproportionate reduction of interest or
is not essentially equivalent to  a dividend will be  made by comparing (i)  the
stockholder's  actual  and constructive  stock interest  in Pinnacle  before the
deemed Pinnacle  redemption  (determined as  if  such stockholder  had  received
solely  Pinnacle Common Stock in the Merger) with (ii) such stockholder's actual
and  constructive  stock  interest  in   Pinnacle  after  the  deemed   Pinnacle
redemption.
 
    With  regard to Financial Security stockholders who receive only cash (i) in
exchange for shares of Financial Security  Common Stock pursuant to the  Merger,
or  (ii) as a result  of the exercise of appraisal  rights, Muldoon has noted in
its opinion  that  many tax  practitioners  believe that  the  determination  of
whether  a cash payment has the effect of a distribution of a dividend should be
made in accordance with the deemed Pinnacle redemption analysis discussed above;
i.e., as if the Financial Security Common Stock exchanged for cash in the Merger
had instead been  exchanged in the  Merger for shares  of Pinnacle Common  Stock
followed  immediately by a  redemption of such  shares by Pinnacle  for the cash
payment. However, under the traditional analysis, which apparently continues  to
be  used by the Service, Section  302 of the Code will  apply as though the cash
payment were  made  by  Financial  Security  in  a  hypothetical  redemption  of
Financial  Security  Common Stock  immediately prior  to,  and in  a transaction
separate  from,  the   Merger  (a  "deemed   Financial  Security   redemption").
Accordingly, under the traditional analysis, the determination of whether a cash
payment   results  in  a  complete  REDEMPTION   of  interest,  qualifies  as  a
substantially disproportionate  reduction  of  interest or  is  not  essentially
equivalent  to a dividend will be made by comparing (x) the stockholder's actual
and  constructive  stock  interest  in  Financial  Security  before  the  deemed
Financial   Security  redemption,   with  (y)  such   stockholder's  actual  and
constructive stock interest  in Financial  Security after  the deemed  Financial
Security  redemption  (but  before the  Merger).  The law  is  unclear regarding
whether the approach  of the  Service is correct,  and Muldoon  has rendered  no
opinion  on the correctness of the Service's  approach. Muldoon has noted in its
opinion that because  the traditional analysis,  as applied by  the Service,  is
more  likely to result in DIVIDEND TREATMENT than the deemed Pinnacle redemption
analysis, each  Financial  Security  stockholder who  receives  solely  cash  in
exchange  for all of the Financial Security Common Stock he or she actually owns
should discuss with his or her tax advisor which analysis is applicable.
 
    The determination of  ownership for  purposes of the  three foregoing  tests
will  be  made  by  taking  into account  both  shares  owned  actually  by such
stockholder and  shares owned  constructively by  such stockholder  pursuant  to
Section  318 of the Code.  Under Section 318 of the  Code, a stockholder will be
deemed to own stock that is actually or constructively owned by certain  members
of  his or  her family (spouse,  children, grandchildren and  parents) and other
related  parties  including,  for  example,  certain  entities  in  which   such
stockholder  has a direct or indirect interest (including partnerships, estates,
trusts and corporations), as well as  shares of stock that such stockholder  (or
related  person)  has  the  right  to acquire  upon  exercise  of  an  option or
conversion right. Section 302(c)(2) of  the Code provides certain exceptions  to
the  family attribution rules for the  purpose of determining whether a complete
 
                                       49
<PAGE>
redemption of a stockholder's interest has occurred for purposes of Section  302
of  the Code. These exceptions apply only to Financial Security stockholders who
receive, in the Merger, solely cash in return for the Financial Security  Common
Stock they actually own.
 
    BECAUSE THE DETERMINATION OF WHETHER A PAYMENT WILL BE TREATED AS HAVING THE
EFFECT  OF  THE  DISTRIBUTION  OF  A DIVIDEND  WILL  GENERALLY  DEPEND  UPON THE
PARTICULAR FACTS  AND  CIRCUMSTANCES  OF EACH  FINANCIAL  SECURITY  STOCKHOLDER,
FINANCIAL  SECURITY STOCKHOLDERS ARE  STRONGLY ADVISED TO  CONSULT THEIR OWN TAX
ADVISORS REGARDING THE TAX TREATMENT OF CASH RECEIVED IN THE MERGER.
 
    Each  Financial  Security  stockholder's  ability  to  elect  the  type   of
consideration  he  or she  receives  pursuant to  the  Merger affords  each such
stockholder the opportunity to select that type of consideration which will best
serve his  or her  personal  tax and  financial  planning needs.  However,  each
Financial  Security  stockholder should  be  aware that  his  or her  ability to
satisfy (or, alternatively,  fail to  satisfy) any  of the  foregoing tests  and
thereby  avoid (or, alternatively, obtain) dividend treatment may be affected by
any redesignation of the stockholder's election by the Exchange Agent.
 
    Each party's obligation to consummate the Merger is subject to the condition
that it shall have received from Muldoon  an opinion to the effect that the  tax
consequences of the Merger will in all material respects be as described in this
section  and that such  opinion shall not  have been withdrawn.  Such opinion is
subject to the conditions and assumptions stated therein and relies upon various
representations made by Pinnacle, Financial Security and certain stockholders of
Financial Security. The opinion  is attached as an  exhibit to the  Registration
Statement  and  copies of  the  opinion will  be  available, without  charge, to
Pinnacle and Financial Security stockholders upon written request. An opinion of
counsel, unlike a private letter ruling from the Service, has no binding  effect
on  the Service. The  Service could take  a position contrary  to the opinion of
Muldoon and, if the matter is litigated,  a court may reach a decision  contrary
to  the  opinion. The  Service is  not expected  to  issue a  ruling on  the tax
consequences of the Merger, and no such ruling has been requested.
 
    THE FOREGOING IS  A GENERAL DISCUSSION  OF CERTAIN OF  THE MATERIAL  FEDERAL
INCOME  TAX CONSEQUENCES OF  THE MERGER AND IS  INCLUDED FOR GENERAL INFORMATION
ONLY. THE FOREGOING DISCUSSION DOES NOT  TAKE INTO ACCOUNT THE PARTICULAR  FACTS
AND  CIRCUMSTANCES  OF  EACH  FINANCIAL SECURITY  STOCKHOLDER'S  TAX  STATUS AND
ATTRIBUTES. AS A RESULT,  THE FEDERAL INCOME TAX  CONSEQUENCES ADDRESSED IN  THE
FOREGOING DISCUSSION MAY NOT APPLY TO EACH FINANCIAL SECURITY STOCKHOLDER.
 
    The following represents a summary of the opinion of Muldoon of the material
federal  income tax consequences  of the Merger  to Pinnacle, Financial Security
and holders of Financial Security Common Stock. The discussion is based upon the
Code, regulations promulgated by the United States Treasury Department,  rulings
of  the Service and  judicial and administrative  decisions in effect  as of the
date hereof, all  of which  are subject  to change  at any  time, possibly  with
retroactive  effect.  This summary  assumes  that shares  of  Financial Security
Common Stock are held as "capital assets" within the meaning of Section 1221  of
the  Code  (i.e., property  generally held  for  investment). In  addition, this
summary does not address all of the  tax consequences that may be relevant to  a
holder  of Financial Security Common Stock  in light of such holder's particular
circumstances or to holders subject to  special rules, such as foreign  persons,
financial  institutions,  tax-exempt  organizations or  insurance  companies. In
addition, this discussion does  not address the tax  consequences to holders  of
options  under  the  Financial Security  stock  option  plans or  to  holders of
Financial Security Common  Stock who  received such stock  as compensation.  The
opinion  of counsel referred to in this  section will be based on facts existing
at the date hereof and  at the Effective Time and,  in rendering the opinion  of
counsel referred to in this section, such counsel assumes the absence of changes
in  existing facts and  will require and rely  upon representations contained in
certificates of officers of Pinnacle, Financial Security and others.

    HOLDERS OF FINANCIAL SECURITY COMMON STOCK SHOULD CONSULT THEIR TAX ADVISERS
AS  TO THE  PARTICULAR TAX  CONSEQUENCES TO  THEM OF  THE MERGER,  INCLUDING THE
APPLICABILITY AND EFFECT  OF ANY FEDERAL,  STATE, LOCAL AND  FOREIGN INCOME  AND
OTHER TAX LAWS.
 
    If  the Merger  occurs in accordance  with the Merger  Agreement, the Merger
will constitute a "reorganization" for federal income tax purposes under Section
368(a) of the Code, with the following federal income tax consequences:
 
        (1)  Financial  Security  stockholders  who  receive  solely  shares  of
    Pinnacle  Common Stock in exchange for their Financial Security Common Stock
    pursuant to the Merger will recognize  no gain or loss, except with  respect
    to cash received in lieu of fractional shares, if any, as discussed below.
 
        (2)  A  Financial Security  stockholder who  receives  only cash  (i) in
    exchange for  shares of  Financial  Security Common  Stock pursuant  to  the
    Merger,  or  (ii) as  a result  of  the exercise  of appraisal  rights, will
    realize gain or loss for federal income tax purposes (determined  separately
    as  to each block of Financial Security Common Stock exchanged) in an amount
    equal to the  difference between  (x) the amount  of cash  received by  such
    stockholder,  and  (y)  such  stockholder's  tax  basis  for  the  shares of
    Financial Security Common Stock  surrendered in exchange therefor,  provided
    that  the cash  payment does not  have the  effect of the  distribution of a
    dividend. Any such gain  or loss will be  recognized for federal income  tax
    purposes  and will be treated as capital  gain or loss. However, if the cash
    payment does have the effect of  the distribution of a dividend, the  amount
    of  taxable  income  recognized  generally will  equal  the  amount  of cash
    received; such income generally will be  taxable as a dividend; and no  loss
    (or  other  recovery  of such  stockholder's  tax  basis for  the  shares of
    Financial Security Common Stock surrendered in the exchange) generally  will
    be  recognized  by such  stockholder. The  determination  of whether  a cash
    payment has  the effect  of the  distribution  of a  dividend will  be  made
    pursuant  to  the provisions  and limitations  of Section  302 of  the Code,
    taking into account the constructive stock ownership rules of Section 318 of
    the Code. See "-- Impact of Section 302 of the Code," above.
 
        (3) A Financial  Security stockholder  who receives  shares of  Pinnacle
    Common  Stock and cash  in exchange for shares  of Financial Security Common
    Stock in the Merger  will realize a gain  (determined separately as to  each
    block  of Financial Security Common  Stock exchanged) if (i)  the sum of the
    amount of cash and the  fair market value of  the shares of Pinnacle  Common
    Stock received by such stockholder exceeds (ii) such stockholder's tax basis
    for  the shares of  Financial Security Common  Stock surrendered in exchange
    therefor. The amount of such gain that is recognized for federal income  tax
    purposes  will be limited to  the amount of cash  received. If the amount of
    cash received exceeds the amount of  gain realized, only the amount of  gain
    realized  will be recognized for federal  income tax purposes. Any such gain
    recognized will be taxable as capital  gain, provided that the cash  payment
    does  not  have the  effect  of the  distribution  of a  dividend.  Any loss
    realized will  not be  recognized  for federal  income tax  purposes.  Under
    section 356 of the Code, the determination of whether a cash payment has the
    effect  of  the  distribution  of  a  dividend  generally  will  be  made in
    accordance with the provisions and limitations  of Section 302 of the  Code,
    taking into account the constructive stock ownership rules of Section 318 of
    the Code. See "-- Impact of Section 302 of the Code" above.
 
        (4)  The aggregate adjusted  tax basis of the  shares of Pinnacle Common
    Stock  received  by  each  Financial  Security  stockholder  in  the  Merger
    (including  any  fractional  share of  Pinnacle  Common Stock  deemed  to be
    received, as  described  in paragraph  (6)  below),  will be  equal  to  the
    aggregate  adjusted tax  basis of  the shares  of Financial  Security Common
    Stock surrendered,  decreased  by  the  amount  of  any  cash  received  and
    increased by the amount of any gain (or dividend) recognized.
 
                                       51
<PAGE>
        (5) The holding period of the shares of Pinnacle Common Stock (including
    any  fractional share  of Pinnacle  Common Stock  deemed to  be received, as
    described in paragraph  (6) below) will  include the holding  period of  the
    shares of Financial Security Common Stock exchanged therefor.
 
        (6)  A Financial Security stockholder who receives cash in the Merger in
    lieu of a fractional share  of Pinnacle Common Stock  will be treated as  if
    the  fractional share had been  received in the Merger  and then redeemed by
    Pinnacle in return for  the cash. The  receipt of such  cash will cause  the
    recipient  to recognize capital gain or loss equal to the difference between
    the amount of cash  received and the portion  of such holder's adjusted  tax
    basis  in the  shares of Pinnacle  Common Stock allocable  to the fractional
    share.
 
CERTAIN DIFFERENCES IN RIGHTS OF STOCKHOLDERS
 
    Upon completion  of  the  Merger, stockholders  of  Financial  Security  who
receive  shares  of Pinnacle  Common Stock  in  exchange for  Financial Security
Common Stock will become stockholders of Pinnacle and their rights as such  will
be  governed by  Pinnacle's Articles of  Incorporation and By-laws,  and will be
governed by Illinois law. The rights  of stockholders of Pinnacle are  different
in certain respects from the rights of stockholders of Financial Security. For a
summary of these differences, see "COMPARATIVE RIGHTS OF STOCKHOLDERS."
 
COMMON STOCK LISTING
 
    Pinnacle  has agreed to cause the shares  of Pinnacle Common Stock to become
listed on the Nasdaq National  Market including the shares  to be issued in  the
Merger.  The obligation of each of Pinnacle and Financial Security to consummate
the Merger is subject to the approval  of trading on the Nasdaq National  Market
of the shares of Pinnacle Common Stock. See "RISK FACTORS."

31, 1995 have been prepared to reflect the proposed Merger between Pinnacle  and
Financial   Security  as  if  the  Merger   had  occurred  on  January  1,  1995
after giving effect to the pro forma  adjustments described in the Notes to  Pro
Forma Statements, which are based on estimates made for the purpose of preparing
these pro forma financial statements. The total Merger Consideration, the number
of  shares  of Pinnacle  Common Stock  issued,  the amount  of cash  payments to
Financial Security stockholders, debt financing needed, cost recorded in  excess
of  fair value of  net assets acquired,  pro forma earnings  per share, and book
value per share could vary based on changes in the Pinnacle Average Stock Price.
The actual adjustments to the accounts of Financial Security will be made on the
basis of more  exact appraisals  and evaluations  that will  be made  as of  the
effective  date  of  the  transaction  and  may,  therefore,  differ  from those
reflected in these pro forma financial statements. In the opinion of  Pinnacle's
management,  the estimates used in the  preparation of these pro forma financial
statements are reasonable under the circumstances. If the Merger is  consummated
as  described  above,  the transaction  will  be  accounted for  as  a purchase.
Accordingly, the consolidated  results of operations  of Financial Security  and
Pinnacle  will be included in the  consolidated financial statements of Pinnacle
for periods subsequent to the Effective Time of the Merger.
 
    These pro forma financial statements should be read in conjunction with  the
historical  financial  statements and  related notes  of Pinnacle  and Financial
Security presented  elsewhere  in  the  Joint  Proxy  Statement/Prospectus.  The
unaudited  pro forma consolidated statements of  condition at March 31, 1996 are
not  necessarily  indicative  of  the   combined  financial  position  had   the
transaction   been  effective  at  March  31,  1996.  The  unaudited  pro  forma
consolidated statements of income are  not necessarily indicative of either  the
results  of operations that would have occurred had the Merger been effective at
the beginning of each period or of the future results of operations of Pinnacle.

NOTES TO PRO FORMA STATEMENTS
The Merger will be accounted for as a purchase and certain adjustments will have
to  be made  with respect  to the  acquired assets  and liabilities  and related
income and expenses of Pinnacle based  on estimated fair market values. The  pro
forma  adjustments contained in the  Pro Forma Consolidated Financial Statements
represent preliminary adjustments. The  actual adjustments will  be made on  the
basis  of  appraisals  and  evaluations  as  of  the  Effective  Date  and these
adjustments  are  not  expected  to   differ  materially  from  the  pro   forma
information.
 
    The  Pro Forma Consolidated Financial Statements have been prepared based on
the maximum and the minimum amount of  Pinnacle shares which could be issued  in
the Merger.
 
    [A]  The maximum  amount of  Pinnacle common  stock, $4.69  par value, which
       could be  issued  in the  Merger  is 1,456,362  shares,  or 100%  of  the
       purchase  price  of $47,149,720  at  a value  of  $32.375 per  share. The
       minimum amount of  Pinnacle common  stock which  could be  issued in  the
       Merger is 800,999 shares, or 55% of the purchase price.
 
    [B]  The  maximum amount  of cash  (corresponding to  the minimum  amount of
       shares issued)  is  approximately $21,217,000,  or  45% of  the  purchase
       price.  Cash  to be  paid to  Financial  Security's shareholders  will be
       incurred as follows:
 
        1.  Conversion of  certain of Security Federal's  securities to fund  an
           $8,000,000 special dividend to Pinnacle.
 
        2.   Use  of excess  cash in the  form of  interest-bearing deposits and
           securities at Financial Security, in the amount of $8,200,000.
 
        3.  The remaining portion  will be incurred as  debt to Pinnacle in  the
           amount of $5,017,000.
 
        Securities   converted  will  total   $10,100,000  and  interest-bearing
       deposits used will total $6,100,000.
 
    [C] Pro forma  interest expense  on the  debt incurred  has been  calculated
       based  on the average LIBOR rate  on similar acquisition debt of Pinnacle
       of 6.89% for the first three months of 1996 and 7.65% for 1995.
 
    [D] The following  table sets forth  the allocation of  the excess  purchase
       price to the specific assets acquired:

PINNACLE'S MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
COMPARISON OF OPERATING RESULTS FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND
1995
 
NET INCOME
 
    Consolidated  net  income was  $1,557,000, or  $0.36 per  share, on  a fully
diluted basis for the three months ended March 31, 1996 (the "first quarter"), a
per share decrease of 53% from the $3,406,000, or $0.77 per share earned in  the
first  three months of 1995.  The annualized return on  average assets was 0.78%
for the first three months of 1996 and 1.67% for the first three months of 1995.
For each period, the return on average equity was 8.7% and 20.7%,  respectively.
Return  on average assets and equity for  the same periods, calculated using the
effects of SFAS No. 115 would not be materially different.
 
    The primary factor for the lower earnings was a 27% decrease in net interest
income in the first quarter  of 1996 compared with the  same period of one  year
ago.  The decrease results with the  narrowing of Pinnacle's net interest margin
to 3.33% compared to 4.58%  for the first three  months of 1995. The  relatively
low  interest rate  environment, coupled  with Pinnacle's  high volume  of U. S.
Government securities and level  yield curve have continued  to put pressure  on
the  net  interest margin,  compressing it  throughout 1995  and into  the first
quarter of 1996. A  decrease in average earning  assets has also contributed  to
the decrease in the net interest margin.
 
    Other income, excluding net securities gains, decreased 8% compared with the
same  period  of 1995.  Other expenses  decreased 6%,  more than  offsetting the
decrease in other income.
 
    NET INTEREST INCOME
 
    The primary component  of Pinnacle's consolidated  earnings is net  interest
income, or the difference between interest income on earning assets and interest
paid  on supporting liabilities. The net  interest margin is net interest income
expressed as a percentage of  average earning assets. Pinnacle's earning  assets
consist   of   loans,   securities,  interest-bearing   deposits   at  financial
institutions and Federal funds sold. Supporting liabilities primarily consist of
deposits, short-term  borrowings  and Pinnacle's  notes  payable. A  portion  of
Pinnacle's    interest   income   is   earned    on   tax   exempt   investments
 
                                       64
<PAGE>
such as state and municipal bonds. In an effort to state this tax exempt  income
and its resultant yields on a basis comparable to all other taxable investments,
an adjustment is made to analyze this income on a taxable equivalent basis.
 
    During  the first  three months of  1996, Pinnacle's  average earning assets
were $736,820,000, a  2% decrease  from the  comparable period  of the  previous
year.  The decrease in  average assets was  primarily in Federal  funds sold and
non-taxable securities, as  a result of  the net decrease  in deposits. The  net
interest margin for the first three months of 1996 was 3.33%, down from 4.58% of
the  same period a year  ago. Net interest income  on a fully taxable equivalent
basis was $6,143,000 for the first three  months of 1996, or 28% lower than  the
comparable  period in 1995. Actual net interest income decreased 27% as a result
of the shrinkage of both the net interest margin and average earning assets.
 
    The yield  earned on  total earning  assets was  6.82% for  the first  three
months  of 1996  compared to  7.88% for  the same  period of  1995. The decrease
resulted from the lower level of yields earned on taxable securities and  loans.
The  average rate on  interest-bearing deposits and  Federal funds sold remained
relatively flat, increasing by only 3 basis points. The average rate on  taxable
securities was 5.38% for the first three months of 1996 compared to 7.13% of the
same  period a  year ago. The  decrease in  the yield on  taxable securities was
primarily a result of the lower level of rates paid on these securities compared
to those carried a year ago. The average volume of taxable securities  increased
$29  million  in  the  comparable period,  with  the  corresponding  decrease in
non-taxable securities. The average rate on non-taxable securities increased  63
basis  points, while the average balance  decreased $22 million. The decrease in
average balances  was due  to the  sale late  in the  first quarter  of 1995  of
certain non-taxable securities which were acquired from AFC with lower rates, as
well as normal maturities of the non-taxable portfolio. The rate earned on loans
decreased  15 basis points due primarily to the decrease in the prime rate since
the first quarter of 1995 as well  as generally lower interest rates on  certain
types of loans, primarily real estate.
 
    The  average cost  of interest-bearing  liabilities increased  only 29 basis
points to 4.06% from 3.77% paid in  the first three months of 1995. The  average
rate  paid  on interest-bearing  demand deposits  and savings  deposits remained
relatively flat while  rates paid on  money market deposits  increased 52  basis
points.  The average rate paid on other time deposits increased 65 basis points.
Pinnacle has taken action  at appropriate intervals to  adjust the rates on  all
deposit  accounts to not only  keep them in line with  market rates, but to meet
the needs of its particular customer  bases. For example, two of the  subsidiary
banks have added a third level of interest rates for certain of its high balance
money market customers, with rates comparable to money market mutual funds. This
move  was done to lessen  the loss of these deposits  to those non-bank types of
investments. Management  began late  in  1994 and  throughout 1995  to  increase
interest  rates on certain time deposits to also keep in line with market rates.
Generally, rates on time deposits have remained flat or dropped slightly in  the
first quarter of 1996, however, the effect of the increases in previous quarters
has  added to the  increase in these rates  paid. The increase  in rates paid on
other time deposits have caused customers to switch their savings deposits  into
other  time deposits,  as evidenced  by the decrease  in the  average balance in
savings deposits and the corresponding increase in the average balance of  other
time deposits.
 
    The average balance in short-term borrowings decreased $2 million, primarily
resulting from less liquidity needs at Pinnacle's savings bank. The average rate
paid  on notes  payable decreased  94 basis  points as  these notes  are tied to
either prime  or  LIBOR-based indices,  which  have decreased  since  the  first
quarter of 1995. The average balance in notes payable decreased approximately $8
million due to paydowns by Pinnacle.
 
    Although  the average balance of interest-bearing liabilities decreased from
the first quarter of 1995, the increase in  rates paid, as well as the shift  of
deposits to higher paying deposit categories, resulted in total interest expense
being  $245,000 higher in  the first three  months of 1996  compared to the same
period of 1995.

March 31, 1996 and 1995 is included on Page 80.

    PROVISION FOR LOAN LOSSES
 
    Management records a provision  for loan losses in  an amount sufficient  to
maintain the allowance for loan losses at a level commensurate with the risks in
the loan portfolio. The allowance for loan losses is adjusted through charges to
current  income based on factors such as past loan loss experience, management's
evaluation of  known potential  losses  in the  loan portfolio,  and  prevailing
economic conditions.
 
    There  was no provision  for loan losses  in the first  three months of 1996
compared to $75,000 for the first three months of 1995. In the fourth quarter of
1995, Pinnacle reversed the provision for loan losses made in the first  quarter
due  to  several factors,  including the  level of  allowance for  possible loan
losses to total  loans, which  has been steadily  increasing for  the last  five
years,  management's assessment of  the overall adequacy  for allowance for loan
losses, as well as the downward trend of net charge-offs to loans. Pinnacle  had
net  recoveries of  $17,000 in the  first three  months of 1996  compared to net
recoveries of $52,000 in 1995. The allowance for loan losses was $6,040,000,  or
1.90% of total loans, at March 31, 1996, compared to 1.95% at December 31, 1995.
 
    Total  nonperforming assets totalled $7,399,000,  down $900,000 from a total
of $8,299,000 at December 31, 1995. Nonperforming assets consisted of $5,331,000
in nonaccrual loans, $946,000 in loans past  due greater than 90 days and  still
accruing,  $908,000 in  restructured loans,  and $214,000  in other  real estate
owned. Over  fifty  percent of  these  nonperforming assets  resulted  from  the
acquisition  of AFC  in 1995.  The investment in  impaired loans  at quarter end
totalled $5,731,000 and are included in the totals above.
 
    NON-INTEREST INCOME AND EXPENSE
 
    The major components  of Pinnacle's non-interest  income consist of  service
charges  on deposit accounts and other banking  income, trust fees and net gains
or losses on the sale of securities.  Fees on banking services and other  income
decreased  $235,000. The decrease  was due primarily  to a $319,000  gain on the
sale of an installment note in the  first quarter of 1995. Absent the effect  of
that  gain, other income increased $84,000, including an increase in fees earned
on the sale of non-bank investment products of $28,000. Trust fees increased 16%
on a period-to-period  basis. Total  trust assets under  management amounted  to
$244,000,000, or an 11% increase of a year ago.
 
    Gains  on the sale of  securities, on a pre-tax  basis, were $264,000 in the
first three months of 1996 compared to net gains of $346,000 in the same  period
of  1995. The net  gains in 1996  are related to  the sales in  Pinnacle's U. S.
Government securities portfolio.
 
    Security sales relating to Pinnacle's U. S. Government securities  portfolio
are  made as part  of Pinnacle's disciplined  portfolio funds management system.
The timing of these sales and  the determination of the acceptable maturity  for
the  reinvestment of the  proceeds is made  dependent on the  slope of the yield
curve and on management's  assessment of the acceptable  interest rate risk  for
Pinnacle.  The use of the  securities portfolio to manage  interest rate risk is
especially crucial to Pinnacle because of the fact that its loan to asset  ratio
is  an unusually low  39%. This results in  a securities portfolio significantly
larger than comparable financial institutions.
 
    Management has always viewed the gains  recorded on this program as  closely
related  to its  net interest  income as opposed  to one-time  security gains or
losses.  Accordingly,  since  implementation  of  the  program,  the  yield   on
Pinnacle's  U. S. Government portfolio has outperformed the U. S. Treasury yield
by 32 basis points and by including the net gain since inception of the program,
the total yield is 142  basis points higher than the  same Index. For the  first
quarter  of 1996, due to the relative flatness of the yield curve, the portfolio
has only outperformed  the Index by  18 basis  points and by  including the  net
gain, by 48 basis points.
 
    Non-interest  expense  decreased  6%  for the  first  three  months  of 1996
compared to the same period last year. The decrease was in other expense,  which
dropped  26%  primarily due  to lower  FDIC  insurance premiums  which decreased
$338,000, and  a  reduction in  data  processing  expenses of  $116,000  due  to
one-time  conversion costs incurred  during the first  quarter of 1995. Employee
 
                                       66
<PAGE>
compensation and benefits increased only 1% on a quarter-to-quarter basis, where
the increase in salaries due to normal raises of approximately 4% were offset by
the planned reduction  in staff that  occurred after the  acquisition of AFC  in
1995. Occupancy expense increased 16% due to the increase in certain real estate
tax  accruals, as well as  greater depreciation due to  a new branch building at
one of Pinnacle's  subsidiary banks  which was put  into service  in the  second
quarter of 1995.
 
    INCOME TAXES
 
    Pinnacle's  Federal income  tax return is  prepared on  a consolidated basis
including the accounts of its subsidiary  banks. The provision for income  taxes
was  $694,000 for the first three months  of 1996 compared with $822,000 for the
first three months of  1995. The lower  provision for taxes  in the first  three
months  of 1996 was  primarily the result  of lower pre-tax  income in the first
quarter of 1996.
 
BALANCE SHEET
 
    Total consolidated assets were $807,489,000 at March 31, 1996, or a 1%  drop
from  year-end 1995. The  decrease, primarily in cash  and cash equivalents, was
the result of the reduction in deposits, primarily demand and savings deposits.
 
    Pinnacle's securities portfolio is its most significant balance sheet asset.
Total securities were  $422,362,000 at  March 31, 1996  and consisted  of U.  S.
Government  securities amounting to $367,952,000, mortgage-backed securities and
CMO's of $9,565,000, state and municipal bonds of $24,571,000, and corporate and
other securities of $20,274,000. The  total securities outstanding at March  31,
1996  was  down 1%  from year-end  1995, however,  the portfolio  at quarter-end
retained relatively the same mix.
 
    U. S. Government securities  amounted to $367,952,000, or  46% of assets  at
March  31, 1996. The average maturity of these securities was approximately four
months. Certain U. S. Government securities (primarily U. S. Treasury bills) are
part of Pinnacle's term taxable securities  strategy which has been designed  to
manage  Pinnacle's interest rate risk and to  take advantage of the slope in the
yield curve. The decision to undertake intermittent sales of these securities is
based on management's assessment of economic conditions. For example, management
will undertake sales of securities based on the slope of the yield curve and its
determination that the  reinvestment of the  proceeds into a  longer or  shorter
term  security  is an  acceptable alternative  given management's  assessment of
interest rate risk.  At March 31,  1996, U. S.  Government securities had  gross
unrealized losses of $261,000 on a pre-tax basis.
 
    Other  securities held by  Pinnacle, amounting to  $54,410,000, at March 31,
1996, consisted of  mortgage-backed, CMO's, state  and municipal, and  corporate
and  equity securities.  At quarter end,  these securities  had gross unrealized
gains of $8,003,000 and gross unrealized  losses of $39,000 on a pre-tax  basis.
Currently,  Pinnacle  is  not using  derivative  products for  hedging  or other
purposes.
 
    Total loans amounted to $318,032,000 at March 31, 1996, up 3% from  year-end
1995.  The  increase was  part of  a  strategic effort  on management's  part to
increase the loan portfolio without sacrificing credit quality of the portfolio.
The  increase  was  primarily  in  commercial  loans,  which  increased  5%   or
approximately  $4,400,000. At March 31, 1996,  28% of the loans were commercial,
real estate  loans  amounted to  56%,  and installment  loans  were 16%  of  the
portfolio. Pinnacle's loan to asset ratio was 39% at March 31, 1996.
 
    Goodwill   and  other  intangibles  amounted   to  $18,706,000,  or  24%  of
stockholders' equity, at March 31, 1996.
 
    Total deposits  were  $703,392,000 at  March  31,  1996, or  1%  lower  than
year-end  1995. The decrease in deposits  was primarily in transaction accounts,
including both noninterest-bearing and interest-bearing demand of  approximately
$7,100,000, which balances fluctuate based on customer needs and are not as rate
sensitive as savings and time deposits. There was also an approximate $4,700,000
drop  in  savings  deposits. Offsetting  the  drop  in savings  deposits  was an
increase in other time deposits of approximately $2,300,000. Management believes
the drop in savings deposits is the
 
                                       67
<PAGE>
result of the customers  attempting to earn higher  rates by moving to  non-bank
products   and  special  term  deposits   at  other  financial  institutions  or
brokerage-type companies. Changing demographics of certain of the banking center
locations has also led to the  shift and loss of deposits. Management  continues
to  take an active role to increase  and maintain interest rates on deposits and
provide products to reduce the disintermediation  of funds. As evidenced by  the
shift  in deposits to other time deposits,  customers are more willing to commit
their funds  to  defined periods  of  time;  Pinnacle's rates  and  new  deposit
products  are  not  only  attracting  new  customers,  but  maintaining existing
customers. At March 31, 1996, the percentage of total deposits for each category
were: Noninterest-bearing deposits, 13%; Interest-bearing demand deposits,  12%;
Savings  accounts  (including  money  market  accounts),  36%;  and  Other  time
deposits, 39%.
 
    Pinnacle's notes payable  were $20,700,000 at  March 31, 1996.  Outstandings
consist  of  $18,000,000  remaining  on  the  note  used  to  purchase  AFC, and
$2,700,000 drawn  on Pinnacle's  revolving  line which  is used  for  purchasing
equity  securities  and other  corporate needs.  At year-end  1995, outstandings
consisted of $20,000,000  on the AFC  note and $600,000  drawn on the  revolving
line.
 
CAPITAL RESOURCES
 
    Total stockholders' equity of Pinnacle was $77,935,000 at March 31, 1996 and
$78,961,000  at December 31, 1995.  The ratio of equity  to assets was 9.65% and
9.64% at each period end, respectively.
 
    The  Federal   Reserve  Board   ("Board")  regulations   prescribe   capital
requirements  for bank holding companies. Pinnacle  must have a Leverage Capital
Ratio with a minimum level  of Tier One capital to  total assets of 3.00%.  Tier
One  capital  consists of  common  stock, additional  paid-in  capital, retained
earnings and is exclusive of Pinnacle's allowance for loan losses, goodwill  and
other  intangibles, and  unrealized gains  (losses) on  securities available for
sale. In addition,  the Board has  issued Risk-Based Capital  Guidelines with  a
minimum  standard of total regulatory capital  to risk weighted assets of 8.00%.
The structure of Pinnacle's balance sheet results in a Risk-Based Capital  Ratio
significantly in excess of the guidelines.
 
    The following table provides an analysis of the minimum capital requirements
(as  defined), ratios and  the excess over  the minimum which  Pinnacle holds as
capital as of March 31, 1996, in thousands (except percentages).

</TABLE>
 
    At December 31, 1995, Pinnacle's total risk-based capital ratio was 18.09%.
 
    In addition, each of Pinnacle's  subsidiary banks must meet similar  minimum
capital  requirements  as prescribed  by  Federal and  state  banking regulatory
authorities. At March 31, 1996, Pinnacle and each of its subsidiary banks was in
compliance  with   the   current   capital   guidelines   and   are   considered
"well-capitalized" under regulatory standards.
 
    Book  value per  share was $17.90  at March  31, 1996 compared  to $18.05 at
December 31, 1995. Dividends amounting to $0.31 per share were paid in the first
three months of 1996.
 
LIQUIDITY
 
    As  characteristic  of  the  banking  industry,  Pinnacle's  indicators   of
liquidity are principally its deposit base, loan and investment portfolios. On a
short  term basis,  adjustments are  made in  these categories  based on deposit
fluctuations and loan  demand. Longer  term, liquidity is  determined by  growth
objectives,  rate  pricing policies  and  the ability  to  borrow debt  or raise
equity. In general,
 
                                       68
<PAGE>
Pinnacle is able  to meet deposit  withdrawals and to  fund loan demand  through
earnings  and the maturity or sale of securities. Pinnacle would also be able to
respond to short term cash flow needs through short term borrowings. On a longer
term basis, Pinnacle has the  ability to incur debt  or to raise equity  through
the sale of preferred or common stock.
 
    Pinnacle's  cash flows are comprised of three general types. Cash flows from
operating activities  are  primarily  Pinnacle's net  income.  Cash  flows  from
investing  activities consist of loans made to and collected from customers; and
purchases, sales and  maturities of  securities available for  sale. Cash  flows
from  financing activities  are determined by  Pinnacle's deposit  base and from
Pinnacle's ability to borrow and repay  debt and issue or repurchase stock.  For
the  three  months  ended March  31,  1996,  cash flows  were  generated  from a
$9,400,000  decrease  in  securities.  Cash  flow  uses  and  needs  included  a
$9,400,000  decrease in deposits, an $8,400,000 net loan principal advanced, and
$1,400,000 to pay dividends. Pinnacle's net cash position decreased  $14,500,000
with  the  decrease  primarily in  Federal  funds  sold of  $11,200,000  and the
remainder in cash and due from banks.
 
    Pinnacle's subsidiary banks have  a relatively stable  base of deposits  and
any  increased loan demand can be  sufficiently funded without a material change
in  its  balance  sheet.  Pinnacle's  corporate  strategy  includes   profitable
acquisitions.   Certain  acquisitions  would  be  primarily  funded  with  debt.
Reductions of debt would be made from Pinnacle's earnings.
 
    At March 31,  1996, Pinnacle had  a line  of credit of  $10,000,000 with  an
unaffiliated  bank  from  which  $2,700,000  had  been  drawn.  The  outstanding
$18,000,000 note related to the AFC acquisition  and is secured by the stock  of
Pinnacle's subsidiary banks.
 
    Regulatory  requirements exist which influence Pinnacle's liquidity and cash
flow needs. These requirements include  the maintenance of satisfactory  capital
ratios  on a consolidated and subsidiary  bank basis, restrictions on the amount
of dividends which a subsidiary bank  may pay and reserve requirements with  the
Federal  Reserve  Bank. Based  on  these restrictions,  at  April 1,  1996, bank
subsidiaries could have declared  approximately $2,244,000 in dividends  without
requesting  approval of  the applicable Federal  or State  regulatory agency. In
addition, Pinnacle has  made loan  commitments which could  result in  increased
cash  flow  requirements for  loans.  Management is  of  the opinion  that these
regulatory requirements and loan commitments will not have a significant  impact
on  the liquidity  of Pinnacle.  Management is  not aware  of any  known trends,
events or uncertainties that will have, or that are reasonably likely to have, a
material  effect  on  Pinnacle  except  the  pending  acquisition  of  Financial
Security.  Management is  also not aware  of any current  recommendations by the
regulatory authorities which,  if implemented,  would have  an adverse  material
effect  on Pinnacle.  There are  several issues  which have  been pending before
Congress, including recapitalization of  the SAIF fund,  and the elimination  of
the  Thrift Charter. The recapitalization of the  SAIF fund is estimated to cost
Pinnacle Bank approximately $1,000,000 on a pre-tax basis.
 
IMPACT OF NEW ACCOUNTING STANDARDS
 
    Effective  January  1,  1996,   Pinnacle  adopted  Statement  of   Financial
Accounting  Standards  ("SFAS")  No.  121,  "Accounting  for  the  Impairment of
Long-Lived Assets and  for Long-Lived Assets  to be Disposed  Of." The  standard
requires  evaluation  of impairment  of long-lived  assets  to be  reviewed when
indicators of impairment are present. Indicators of impairment include, but  are
not  limited to  a significant  decrease in the  market value  of an  asset or a
significant change in  the manner an  asset is  used. The cost  of the  impaired
asset  is then  compared to its  fair value,  and any impairment  is recorded in
current earnings. There was no  effect of the adoption  of this standard on  the
financial position and results of operations of Pinnacle.
 
    In  October, 1995, SFAS  No. 123, "Accounting  for Stock-Based Compensation"
was issued. The statement is effective for fiscal years beginning after December
15, 1995.  This statement  establishes accounting  and reporting  standards  for
stock-based  awards, such  as stock options,  granted in  fiscal years beginning
after December 15, 1994. SFAS No. 123 establishes a fair value of accounting for
stock options, with compensation  expense reported for the  fair value of  these
types of instruments in
 
                                       69
<PAGE>
current  earnings. Entities  may elect  not to  adopt the  fair value  method of
accounting, but are  required to make  pro forma disclosures  of net income  and
earnings  per share as if the statement was adopted. Pinnacle has elected not to
adopt the provisions of SFAS No. 123 and will make pro forma disclosures on  the
effects,  which are anticipated to  be immaterial, in the  1996 Annual Report to
Shareholders.
 
COMPARISON OF OPERATING RESULTS FOR THE YEARS ENDED DECEMBER 31, 1995 AND
DECEMBER 31, 1994
 
NET INCOME
 
    Consolidated net income  was $12,493,000,  or $2.83  per share,  on a  fully
diluted  basis in  1995, an  increase from the  $2,255,000, or  $0.51 per share,
earned in 1994. The return  on average assets was 1.55%  for 1995 and 0.32%  for
1994.  For  each  year,  the  return  on  average  equity  was  18.1%  and 3.4%,
respectively. Return on average assets and equity for 1995, calculated including
the effects of SFAS No. 115 would not be materially different.
 
    Net income for 1995 included pre-tax securities gains of $4,730,000 compared
with $(9,845,000)  of  net  securities  losses in  1994.  The  majority  of  the
securities  gains were taken in the second quarter  of 1995 and were part of the
ongoing term portfolio management system which Pinnacle has followed since 1988.
 
    Net interest income increased 5%, primarily  as a result of the increase  in
average  earning assets of  14% due to  the acquisition of  Acorn Financial Corp
("AFC").
 
    Other factors  contributing to  the  improved earnings  for Pinnacle  was  a
decrease  in the provision for  loan losses and the  increase in other operating
income due to the acquisition. Other operating expense was up 13% also primarily
due to the acquisition.
 
    The results for 1995 include the acquisition of AFC and its subsidiary bank,
Suburban Trust  & Savings  Bank, on  January 6,  1995. AFC  was liquidated  into
Pinnacle  and concurrent  with the  liquidation, Suburban  Trust &  Savings Bank
("Suburban") was  merged  with  Pinnacle  Bank,  a  wholly-owned  subsidiary  of
Pinnacle. The acquisition was accounted for as a purchase. Results of operations
of  Suburban,  including purchase  accounting adjustments,  are included  in the
operating results of Pinnacle Bank.
 
    NET INTEREST INCOME
 
    Pinnacle's average earning assets were  $744,318,000 in 1995, or 14%  higher
than  the previous year. The  increase in average earning  assets was due to the
acquisition. The net interest  margin for 1995 was  3.90% compared to 4.28%  for
1994.  The  decrease in  the  net interest  margin has  been  the result  of the
relatively low level of interest rates coupled with the structure of  Pinnacle's
balance  sheet, its low loan-to-deposit ratio,  and high volume of short-term U.
S. Government securities. Net  interest income on  a fully tax-equivalent  basis
was  $29,019,000 in 1995, or 4% higher  than in 1994. Actual net interest income
increased 5%.
 
    The yield earned on total earning assets was 7.36% in 1995 compared to 6.83%
in 1994. The  increase resulted from  a higher  level of interest  rates in  the
entire  year  of 1995  compared  to 1994.  As a  result  of the  reinvestment of
securities proceeds  from  the  term portfolio  management  system  into  higher
yielding  securities, the average rate on  taxable securities was 6.16% for 1995
compared to  5.29% of  a year  ago.  The average  volume of  taxable  securities
increased $11,851,000 due to the acquisition of Suburban. This, coupled with the
increased  yield, increased interest income on taxable securities by $3,909,000.
The average yield earned on loans increased to 8.54% for 1995 compared to  8.31%
of  a year ago. While the  increase in the yield on  average loans is not large,
the ratio of average loans to average earning assets was 41.6% in 1995  compared
to  38% of a year ago. The average  volume of loans increased to $309,818,000 or
25% in  1995 due  to the  acquisition. The  average yield  earned on  short-term
investments  increased 124 basis points to  5.55% in 1995 while average balances
increased $17,395,000.  Total interest  income, on  a fully  taxable  equivalent
basis,  increased $10,206,000 due to both the positive effect of the increase in
interest rates and the increase in the level of average earning assets.
 
                                       70

    The average cost of interest-bearing liabilities increased 100 basis  points
to  4.02% in 1995 from 3.02% in  1994. The average rate paid on interest-bearing
demand and savings deposits increased 35 basis points. The average rate paid  on
money  market deposits increased  38 basis points. Pinnacle  has taken action at
appropriate intervals to  adjust the rates  paid on these  accounts in order  to
keep  these accounts in line  with market rates. The  average rate paid on other
time deposits  has had  the largest  increase due  to changes  in the  level  of
interest  rates,  with a  145 basis  point  increase. Absent  the effect  of the
acquisition,  the  average  balances  in  certain  of  the  deposit  categories,
including  savings deposits and money market deposits have decreased while other
time deposits  have  increased.  Management believes  the  decrease  in  savings
deposits  is partially the result of  the previous low interest rate environment
where customers  attempted  to  achieve  higher yields  by  switching  funds  to
non-bank  investments or special-term deposits  at other financial institutions.
Additionally,  certain  of   the  banking   locations  are   in  older,   mature
neighborhoods  where  the  deposits are  being  lost  due to  death,  moving, or
changing demographics of the neighborhood.  Management has taken steps to  limit
the disintermediation of funds by raising interest rates in certain time deposit
categories  beginning in  the latter half  of 1994 and  continuing through 1995.
Special-term deposits have also been introduced. Management has also added other
deposit options including free checking, as well as non-bank investment choices,
for its customer base. While the non-bank investment option does not necessarily
retain or attract  new deposits, the  fee income generated  offsets some of  the
cost  of lost deposits.  These steps have  resulted in new  accounts and current
customers' committing their  funds to longer  time periods as  evidenced by  the
increase  in average time deposit balances.  All these moves by management have,
however, added to the increase in the rate paid on certain deposit categories as
indicated above.
 
    The average balance in  short-term borrowings decreased  due to the  greater
availability  of investible  funds resulting  from the  acquisition. The average
balance in notes payable increased to $24,684,000 due to the acquisition of AFC.
The average rate paid on notes payable has increased as the rates paid on  these
notes  are tied  to either  prime or  LIBOR-based indices,  which have increased
since 1994.
 
    As a result  of the increase  in rates  paid, as well  as average  balances,
total interest expense was $9,099,000 higher in 1995 compared to 1994.
 
    PROVISION FOR LOAN LOSSES
 
    Effective   January  1,  1995,  Pinnacle  adopted  Statements  of  Financial
Accounting Standards ("SFAS") No. 114,  "Accounting by Creditors for  Impairment
of  a Loan", and its amendment No.  118, "Accounting by Creditors for Impairment
of a Loan -- Income Recognition and Disclosure". The adoption of these standards
did not have any effect on the  financial position and results of operations  of
Pinnacle.
 
    Management's  system  of  review of  the  loan portfolio  and  the attendant
determination of the adequacy of the allowance  for loan losses is made up of  a
number  of factors. The most  significant part of the  system is the independent
credit review system which reviews all commercial credits in excess of  $100,000
and  all commercial real estate credits in excess of $250,000 on an annual basis
at a  minimum,  with  problem  credits reviewed  more  often  as  necessary.  An
informed,  judgmental determination  is made of  the risk  associated with loans
which have received low  grades under the credit  review system. This  estimated
risk  as well as  any valuation allowances  related to impaired  loans are taken
into account in  determining the  allowance for  loan losses.  In addition,  the
allowance includes additional reserves for coverage of unidentified risks.
 
    In  addition to the credit  review system, on a  quarterly basis an internal
report provides an analysis of the adequacy of the allowance for management  and
the  Board  of Directors.  This analysis  focuses on  allocations based  on loan
review ratings  and historical  charge-off and  recovery data.  Management  also
reviews the status of all watch list credits on a monthly basis. The process and
the  amount of the allowance and of the  provision have also been subject to the
review of external auditors
 
                                       71
<PAGE>
and banking regulatory authorities. Management believes that it has an effective
system of credit review  assessment demonstrated by the  fact that Pinnacle  has
not  recorded  a significant  loss  from a  loan  that had  not  been previously
identified as a watch list credit by the loan review process.
 
    There was no  provision for  loan losses in  1995 compared  to $900,000  for
1994.  Pinnacle had net charge-offs  of $151,000, or 0.05%  of average loans, in
1995 compared to net charge-offs of $218,000, or 0.09% of average loans in 1994.
The allowance for loan losses was $6,023,000, or 1.95% of loans, at December 31,
1995, compared to 1.70% of loans at year-end 1994. The decrease in the provision
for loan losses  to zero from  $900,000 of a  year ago was  made due to  several
circumstances,  including the  level of  allowance for  possible loan  losses to
total loans,  which  has been  steadily  increasing  for the  last  five  years,
management's  assessment  of  the overall  adequacy  of the  allowance  for loan
losses, as well as the downward trend of net charge-offs to average loans.
 
    At December  31, 1995,  nonperforming loans,  defined as  nonaccrual  loans;
loans  past due greater than 90 days and still accruing; and restructured loans,
were $8,015,000 compared with  $1,300,000 at the previous  year end. While  this
increase  is significant, approximately 50% of these loans are attributed to the
acquisition in  1995.  At the  date  of the  acquisition,  AFC was  required  by
Pinnacle  to  have a  reserve  of at  least  2.5% of  total  loans to  cover the
potential problem loans in the portfolio as well as those loans which were noted
during the due diligence  performed by Pinnacle. A  restructured loan which  was
acquired  from AFC, included  in the above  total, is current  and performing as
agreed. Loans considered impaired under  SFAS No. 114 include nonaccrual  loans,
restructured  loans, and loans classified as  at least doubtful under Pinnacle's
credit risk classification system. All of Pinnacle's impaired loans are included
in the nonperforming category.
 
    In addition, Pinnacle held  $284,000 classified as  other real estate  owned
("OREO")  at December  31, 1995.  Other real  estate includes  property acquired
through foreclosure or deed in lieu of foreclosure. These assets are carried  at
the  lower of fair value less estimated cost  to sell or cost. Losses arising at
the time of acquisition of property in full or partial satisfaction of loans are
recorded as  loan losses.  Subsequent losses  or expenses  on the  property  are
charged  to other expenses.  Income received on  the property is  recorded as an
offset to expense. During  1995, all property carried  at December 31, 1994  was
sold with no significant impact on the results of operations. The remaining OREO
consists of three properties from AFC which are actively being offered for sale.
 
    Total  nonperforming assets  were $8,299,000, or  2.68% of  total loans plus
other real estate owned  at December 31, 1995.  Total nonperforming assets  were
1.01% of total assets at year end.
 
    NET SECURITIES GAINS
 
    In  1995, a significant factor contributing  to Pinnacle's higher net income
was net  securities  gains.  On  a pre-tax  basis,  net  securities  gains  were
$4,730,000 compared to losses of $(9,845,000) in 1994. The net gains realized in
1995 consisted of gross gains of $5,079,000 and gross losses of $349,000.
 
    The majority of the net securities gains recorded by Pinnacle related to its
U. S. Government securities portfolio. Sales of these securities resulted in net
securities  gains of  $3,586,000 recorded in  1995 and net  securities losses of
$(11,392,000) recorded  in 1994.  The  securities sales  were  made as  part  of
Pinnacle's  disciplined portfolio funds  management system. The  majority of the
gain taken on securities transactions was in the second quarter and consisted of
U. S. Government securities with  a maximum maturity of  less than one year.  At
December  31, 1995, the U. S. Government  securities had a remaining maturity of
four months.
 
    The timing of these sales and  the determination of the acceptable  maturity
for  the reinvestment  of the proceeds  was made  dependent on the  slope of the
yield curve and on management's assessment of the acceptable interest rate  risk
for  Pinnacle. The use of the securities  portfolio to manage interest rate risk
is especially crucial to  Pinnacle because of  the fact that  its loan to  asset
ratio was a low 38% at December 31, 1995. This results in a securities portfolio
significantly larger than comparable financial institutions. The maximum term of
any U. S. Government security held as part of Pinnacle's term portfolio strategy
is four years although at year-end, the longest maturity of any single issue was
four
 
                                       72
<PAGE>
months  based on management's assessment of interest rate risk. Management views
the portion of the net  gains recorded on this program  due to slope as  closely
related  to  its  net interest  income  as  opposed to  a  one-time  item. While
management believes that its system of portfolio strategy, as it relates to  the
slope  of the yield  curve, will continue  to add dollars  to earnings above the
base yield on securities, management also recognizes that in a period of  rising
interest  rates, any rise in the interest margin would be offset by losses taken
through the term portfolio strategy. While  this scenario occurred in 1994,  the
proceeds  of those sales and subsequent sales  in 1995 were reinvested at higher
interest rates, and the loss in 1994 was recovered by the resulting increase  in
the net interest margin prior to the original maturity of the securities sold in
1994. Since implementation of the program, the average yield on these securities
has  outperformed the U. S.  Treasury Index by 31  basis points and by including
the net gain for the period, the total yield is 145 basis points higher than the
same Index.
 
    The net securities gains recorded in 1995 included gains of $695,000 related
to Pinnacle's equity investment program  which consists of preferred and  common
stock investments in other financial institutions. The remaining gains relate to
the sale of securities acquired through the AFC purchase.
 
    OTHER NON-INTEREST INCOME
 
    The  major  components of  Pinnacle's other  non-interest income  consist of
service charges on deposit accounts, other  banking income and trust fees.  Fees
on  banking  services and  other  income were  $4,918,000  for 1995  compared to
$3,704,000 in 1994, an increase of 33%. The primary source of banking fee income
in 1995 was  deposit service charges  totalling $3,139,000, an  increase of  32%
from  the $2,379,000  level of  1994, due to  the acquisition.  Also included in
other banking income was a gain  of approximately $319,000 relating to the  sale
of  an installment note included in Other  Assets. Trust fees increased 31% on a
year-to-year basis. Trust assets under management  at year end amounted to  $241
million  at December 31, 1995, or 44% above the total one year earlier. Both the
increase in trust fees and trust assets resulted from the acquisition.
 
    NON-INTEREST EXPENSE
 
    Non-interest expense  totalled  $23,882,000,  an increase  of  13%  in  1995
compared  to 1994. Employee  compensation and benefits  increased 27%, primarily
due to the  acquisition, higher profit  incentive bonus accruals  due to  higher
1995   earnings  and   general  employee  raises.   Occupancy  expense  totalled
$3,137,000, up  70%  from  1994. While  the  acquisition  of AFC  added  to  the
increase,  occupancy  expense  also  included a  planned  write-off  of $434,000
relating the  demolition  of an  old  branch  office building  (a  new  building
contiguous  to the old site was opened in June, 1995) and a $150,000 accrual for
a lease buy out  on a storage  facility which occurred  in January, 1996.  Other
expense  decreased 16%. These expenses were reduced by approximately $364,000 as
a result of the FDIC insurance premium rebate. Also included in other  operating
expenses  in  1994  was  a  loss  contingency  charge  of  $750,000  relating to
litigation which was settled  in the last quarter  of 1995. Legal expenses  also
decreased  on a year-to-year basis, down  $310,000. This decrease was the result
of the settlement of several pending litigation  items as well as sale in  early
1995  of  certain pieces  of OREO.  Other  expenses relating  to that  OREO also
decreased $154,000. Offsetting these decreases  were increases in equipment  and
data  processing costs associated  with the conversion to  a new data processing
system for Pinnacle that was  completed in 1995 as  well as expenses related  to
the acquisition of AFC.
 
    INCOME TAXES
 
    Pinnacle's  Federal income  tax return is  prepared on  a consolidated basis
including the  accounts of  its subsidiary  banks. Due  to the  higher level  of
pre-tax income in 1995, there was a tax provision of $3,139,000 in 1995 compared
to  a benefit of $(2,319,000) in 1994.  The primary components of Pinnacle's net
deferred tax asset at December 31, 1995 are differences between the book and tax
bases of  securities  and other  assets,  allowance for  loan  losses,  purchase
accounting  adjustments,  deferred  compensation  and  deferred  loan  fees.  At
December   31,    1995,    Pinnacle    had   a    consolidated    Federal    net
 
                                       73
<PAGE>
operating  loss carryforward of $3,641,000, which  if not used, expires from the
years 1999 to 2001. The majority of the Federal net operating loss  carryforward
relates  to the parent company and is  subject to significant limitations on its
usage.
 
    There was no provision for state income taxes in 1995 compared to a  benefit
of  $(761,000)  in 1994.  There was  no state  tax  benefit in  1995 due  to the
significant holdings of U. S. Government securities which are exempt from  state
tax.  Additionally, all carryback claims for  losses were utilized in 1994, with
carryforwards remaining. The tax benefit in 1994 related to low pre-tax earnings
for Pinnacle and the ability  to carryback losses for  state tax purposes for  a
refund  of previously paid taxes. At December  31, 1995, Pinnacle had, for state
tax purposes, a net operating loss carryforward of $23,549,000 which expires  in
the years 2010 and 2011.
 
COMPARISON OF OPERATING RESULTS FOR THE YEARS ENDED DECEMBER 31, 1994 AND
DECEMBER 31, 1993
 
NET INCOME
 
    Consolidated  net  income was  $2,255,000, or  $0.51 per  share, on  a fully
diluted basis in  1994, a per  share decrease  of 82% from  the $12,993,000,  or
$2.87  per share earned in 1993. The return on average assets was 0.32% for 1994
and 1.80% for 1993.  For each year,  the return on average  equity was 3.4%  and
18.9%,  respectively. Return on  average assets and  equity for 1994, calculated
including the effects of SFAS No. 115 would not be materially different.
 
    Net income  for  1994 included  pre-tax  securities losses  of  $(9,845,000)
compared  with $8,741,000 of net  securities gains in 1993.  The majority of the
securities losses were taken in the second quarter of 1994 and were part of  the
ongoing term portfolio management system which Pinnacle has followed since 1988.
 
    While  the rising interest rate environment  created the losses taken in the
portfolio,   the   proceeds   of   those   transactions   were   reinvested   in
higher-yielding,  shorter-term securities which, in  turn, had a direct positive
impact on  the  net interest  margin  in  1994. Net  interest  income  increased
$3,171,000, or 14% over 1993. In 1994, there was a decrease in the provision for
loan  losses of  $800,000, or  47%. Other  operating income  decreased 3%, while
other operating expense increased 3%. Due to the effect of the securities losses
in 1994, there was an income tax  benefit of $(2,319,000) versus a provision  of
$4,005,000 in 1993.
 
    NET INTEREST INCOME
 
    Pinnacle's  average earning  assets were $652,080,000  in 1994,  or 3% lower
than the previous year. The  decrease in average earning  assets was due to  the
corresponding  decrease in deposits,  primarily in other  time deposits. The net
interest margin for 1994 was 4.28% compared  to 3.70% for 1993. The increase  in
the  net interest  margin resulted  from the  reinvestment of  proceeds from the
securities transactions into higher-yielding securities, a higher ratio of loans
to average earning assets in 1994 and  the general lag in the repricing of  core
savings deposits in an increasing interest rate environment. Net interest income
on  a fully tax-equivalent basis was $27,912,000  in 1994, or 12% higher than in
1993. Actual net interest income increased 14%.
 
    The yield earned on total earning assets was 6.83% in 1994 compared to 6.31%
in 1993. The increase  resulted from a  higher level of  interest rates in  1994
compared  to 1993.  As a  result of the  reinvestment of  securities proceeds in
higher yielding securities, the average rate on taxable securities was 5.29% for
1994 compared  to 4.56%  of a  year ago.  While the  average volume  of  taxable
securities  declined $21,932,000 due to the  reduction in deposits, the increase
in yield earned on taxable securities more than offset the decline in volume and
thus increased interest income on taxable securities by $1,682,000. The  average
yield  earned on loans increased  to 8.31% for 1994 compared  to 8.21% of a year
ago. While the increase in the yield on average loans is not large, the ratio of
loans to average earning assets was 38% in  1994 compared to 35% of a year  ago.
The  average volume  of loans  increased $9,174,000 or  4% in  1994. The average
yield earned on short-term investments increased 139 basis
 
                                       74
<PAGE>
points to 4.31% in  1994. Total interest income,  on a fully taxable  equivalent
basis, increased $1,940,000 with the positive effect of the increase in interest
rates outweighing the decrease in the level of average earning assets.
 
    The  average cost of interest-bearing liabilities declined 7 basis points to
3.02% in 1994  from 3.09%  in 1993. The  average rate  paid on  interest-bearing
demand  and savings deposits  declined 22 basis  points. This drop  is much less
than the  drop  in 1993  from  1992  of 70  basis  points. Due  to  the  rapidly
increasing  interest rate environment, Pinnacle  has taken action at appropriate
intervals to adjust  the rates paid  on these  accounts in order  to keep  these
accounts  in  line with  market  rates. The  average  balance of  these accounts
dropped $7,352,000 or  2% from  1993. The average  rate paid  on time  deposits,
conversely,  has increased 8 basis points. The average balance of these accounts
has decreased $14,242,000, or 7% from  a year ago. Management believes that  the
decline  in  these deposits  is the  result  of the  previous low  interest rate
environment and the  customer's attempt  to achieve higher  yields by  switching
funds  to  non-bank  investments  or special-term  deposits  at  other financial
institutions. Management has taken  steps by raising  interest rates in  certain
time   deposit  categories  in  the  last  six  months  of  1994  to  limit  the
disintermediation of  these funds.  This move  by management  has added  to  the
increase  in the  average rate  paid on  time deposits  which, until  the fourth
quarter of  1994, had  declined  15 basis  points.  Total interest  expense  was
$1,030,000 lower in 1994 compared to 1993, primarily as a result of the decrease
in average balances of interest-bearing deposits.
 
    PROVISION FOR LOAN LOSSES
 
    The  provision for loan losses was  $900,000 for 1994 compared to $1,700,000
for 1993. Pinnacle had net charge-offs  of $218,000, or 0.09% of average  loans,
in  1994 compared to net charge-offs of $1,154,000, or 0.48% of average loans in
1993. The net  charge-off amount recorded  in 1993 was  primarily the result  of
charge-offs totalling $1,232,000 related to two loans secured by commercial real
estate.  The allowance  for loan  losses was $4,229,000,  or 1.70%  of loans, at
December 31, 1994, compared to 1.43% of loans at year-end 1993. The decrease  in
the  provision for loan losses  of $800,000 at year-end  1994, compared with the
previous year-end,  was  reflective of  the  decreased level  of  non-performing
assets.
 
    At  December  31, 1994,  nonperforming loans,  defined as  nonaccrual loans;
loans past due greater than 90 days and still accruing; and restructured  loans,
were  $1,300,000 compared with $5,868,000 at the previous year end. The decrease
in nonperforming loans is  attributable to the payment  of principal in full  of
one  loan  totalling  $1,300,000; the  return  to  accrual of  a  loan totalling
$1,900,000 which has continued to  perform, with principal reductions in  excess
of  $1,000,000; and the return to accrual  of a loan which is adequately secured
by real estate and on which payments are current. If non-accrual loans had  been
accruing  interest at their  original terms in  1994, additional interest income
would have amounted to $66,000.
 
    NET SECURITIES LOSSES
 
    In 1994, the most  significant factor contributing  to Pinnacle's lower  net
income was net securities losses. On a pre-tax basis, net securities losses were
$(9,845,000) compared to gains of $8,740,000 in 1993. The net losses realized in
1994 consisted of gross losses of $12,440,000 and gross gains of $2,595,000.
 
    The  majority of the  net securities losses recorded  by Pinnacle related to
its U. S. Government securities portfolio. Sales of these securities resulted in
net securities losses of $11,392,000 recorded  in 1994 and net securities  gains
of  $7,311,000  recorded in  1993. The  securities  sales were  made as  part of
Pinnacle's disciplined portfolio  funds management system.  The majority of  the
loss taken on securities transactions was in the second quarter and consisted of
U.  S. Government securities  with a maximum  maturity of 24  months. During the
third quarter,  the  average maturity  was  shortened with  little  loss  taken.
Additional  losses of approximately $3,200,000 recorded  in the final quarter of
1994 were taken on these U.  S. Government securities with the continued  intent
of  shortening the average maturity of the term portfolio. At December 31, 1994,
the U. S. Government securities had a remaining maturity of five months.
 
                                       75
<PAGE>
    The timing of these sales and  the determination of the acceptable  maturity
for  the reinvestment  of the proceeds  was made  dependent on the  slope of the
yield curve and on management's assessment of the acceptable interest rate  risk
for  Pinnacle. The use of the securities  portfolio to manage interest rate risk
is especially crucial to  Pinnacle because of  the fact that  its loan to  asset
ratio was a low 36% at December 31, 1994. This results in a securities portfolio
significantly  larger than comparable financial institutions. While the majority
of the losses taken on the term portfolio in 1994 resulted from the  significant
rise in interest rates since the beginning of 1994, management continues to feel
that  its system of portfolio  strategy as it relates to  the slope of the yield
curve will  continue  to  add  dollars  to earnings  above  the  base  yield  on
securities.  Because of the rising interest rate environment of 1994 and despite
the shortening of the average maturity throughout the year, reinvestment of  the
proceeds  of the securities sales were made  at yields greater than the rates on
securities sold, thus offsetting the effect of the losses by increasing the  net
interest margin.
 
    The  net  securities gains  recorded in  1994  included gains  of $1,772,000
related to Pinnacle's equity investment program which consists of preferred  and
common  stock investments in  other financial institutions.  The remaining gains
were recorded on the term portfolio early in the first quarter of 1994.
 
    OTHER NON-INTEREST INCOME
 
    The major  components of  Pinnacle's other  non-interest income  consist  of
service  charges on deposit accounts, other  banking income and trust fees. Fees
on banking  services and  other  income were  $3,704,000  for 1994  compared  to
$3,903,000  in 1993, a decrease of 5%.  The primary source of banking fee income
in 1994 was deposit service charges totalling $2,379,000, a drop of 10% from the
$2,632,000 level of 1993. A significant  portion of the drop in service  charges
related  to business  deposit accounts. In  a rising  interest rate environment,
these customers  earn greater  credit on  their balances,  thus offsetting  fees
charged.  Trust fees  increased 3% on  a year-to-year basis.  Trust assets under
management at year  end amounted to  $167 million  at December 31,  1994, or  2%
above the total one year earlier.
 
    NON-INTEREST EXPENSE
 
    Non-interest  expense  totalled  $21,060,000,  an  increase  of  3%  in 1994
compared to 1993. Employee compensation and benefits decreased 1%, primarily  as
a  result of lower profit  incentive bonus accruals due  to lower 1994 earnings.
Occupancy expense totalled $1,848,000, down 4%. Other general expenses  amounted
to  $8,072,000, up 11%.  Included in other  general expenses was  a provision of
$750,000 for  issues  currently in  litigation.  Without these  reserves,  other
expenses would have been unchanged.
 
    INCOME TAXES
 
    Due  to the high level of securities losses in 1994, there was a tax benefit
of $(2,319,000) in  1994 compared  to a provision  for $4,005,000  in 1993.  The
primary  components of  Pinnacle's deferred tax  asset at December  31, 1994 are
differences between  the book  and tax  bases of  securities and  other  assets,
provision   for   loan  losses,   purchased  accounting   adjustments,  deferred
compensation and  deferred loan  fees.  At December  31,  1994, Pinnacle  had  a
consolidated  net operating loss carryforward of  $3,641,000, which if not used,
expires from the  years 1999 to  2001. The  majority of the  net operating  loss
carryforward  relates  to  the  parent company  and  is  subject  to significant
limitations on its usage.
 
    The provision for state income taxes in 1994 was a tax benefit in the amount
of $(761,000) compared to a  benefit of $(108,000) in  1993. The tax benefit  in
1994   related  to  low  pre-tax  earnings  for  Pinnacle  and  from  Pinnacle's
significant holdings of U. S. Government securities, which are exempt from state
tax, and the ability to carryback losses for state tax purposes for a refund  of
previously paid taxes.

BALANCE SHEET
 
    Total  assets were  $818,697,000 at  December 31,  1995, or  20% higher than
total assets of  $684,892,000 at  year-end 1994.  The increase  in total  assets
relates to the acquisition of AFC on January 6, 1995.
 
    SECURITIES
 
    Pinnacle's securities portfolio is its most significant Balance Sheet asset.
Total  securities were $426,929,000 at December 31,  1995 and consisted of U. S.
Government securities of  $370,545,000; MBS's and  CMO's totalling  $10,306,000;
State  and municipal bonds of $25,839,000  and Corporate and other securities of
$20,238,000. Total securities outstanding increased 10% from 1994. The  increase
was  primarily due to  the acquisition of AFC.  Certain securities acquired from
AFC which  were  not within  Pinnacle's  investment guidelines  were  sold  with
proceeds reinvested primarily in U. S. Government securities.
 
    Currently,  Pinnacle is  not using  any derivative  products for  hedging or
other purposes.
 
    Pinnacle adopted SFAS No. 115, effective January 1, 1994 and classified  all
securities  held by Pinnacle as available for  sale. As a result, all securities
are carried on the Balance Sheet  at fair value, with corresponding (after  tax)
valuation  adjustments included  in stockholders'  equity. During  the year, the
change in the valuation  adjustment was an increase  of $4,004,000 resulting  in
total unrealized gains, net of tax, of $7,052,000 at December 31, 1995.
 
    LOANS
 
    Total  loans were $309,600,000 at December 31, 1995, an increase of 25% over
loans outstanding of $248,404,000 at December 31, 1994. All categories of  loans
increased  due to the acquisition, with the greatest increase in commercial real
estate  loans.  Absent   the  effects  of   the  acquisition,  loans   increased
approximately  $3,000,000, with the majority of the increase in both residential
and commercial real estate  loans. Pinnacle's loan to  asset ratio increased  to
38%  at  December 31,  1995; although  it remains  significantly lower  than the
industry average.  Factors which  contribute  to the  low  loan to  asset  ratio
include  the market areas in  which certain of the banks  are located as well as
certain acquisitions in recent years, such  as Berwyn National Bank acquired  in
1991  with a  13% loan  to asset ratio  and the  acquisition of  $120 million in
deposits of the  Berwyn branch of  Olympic Federal Savings  Association in  1992
with no corresponding loans. Management's goal is to increase this ratio through
quality  loan growth  across a consistent  spectrum of  commercial, consumer and
real estate borrowers.  Management targets  borrowers who  are or  will be  full
relationship banking customers as opposed to single product loan customers.
 
    At  December 31,  1995, Pinnacle's  mix of  loans consisted  of 57%  in real
estate loans, 27% in commercial loans and 16% in consumer loans, which  remained
substantially  consistent with  the mix at  December 31,  1994. Commercial loans
declined while consumer  installment loans increased.  A substantial portion  of
Pinnacle's  loans are owner-occupied, one-to-four  family residences, as well as
consumer related with  home equity and  home improvement loans.  This mix is  in
line with Pinnacle's focus on increasing the importance of retail lending.
 
    DEPOSITS
 
    Total  deposits were $712,805,000  at December 31, 1995,  or 19% higher than
year-end 1994. The  majority of  the increase  in deposits  is a  result of  the
acquisition.
 
    Absent  the  effect  of  the  acquisition,  savings  deposits  have  dropped
approximately $21,000,000 and money  market deposits have dropped  approximately
$9,000,000.  Other  time  deposits  have  increased  approximately  $21,000,000.
Management believes the drop in savings and money market deposits is the  result
of  the low  interest rate  environment in years  prior to  1994 where customers
earned similar rates  on their  savings deposits as  they would  have with  time
deposits  without long-term  commitment of  funds. As  the rates  began to rise,
customers attempted to  earn higher  rates by  moving to  non-bank products  and
special   term   deposits  at   other   financial  institutions   or  brokerage-
 
                                       77
<PAGE>
type companies. Changing demographics of certain of the banking center locations
has also led to the  shift and loss of deposits.  During the last half of  1994,
and  continuing  throughout 1995,  management has  taken  steps to  increase and
maintain  interest  rates  on  deposits  and  provide  products  to  reduce  the
disintermediation  of funds. Deposits have shifted from savings and money market
deposits into time  deposits, indicating  customers are more  willing to  commit
their funds for defined periods of time.
 
    Pinnacle's deposit base continues to be made up of a high amount of low cost
core deposits in comparison with peer group institutions. However, the impact on
earnings  of  this  deposit  base  has  been  somewhat  offset  in  the  current
environment due to increased rates paid on these deposits. Also, the increase in
rates paid  on  time deposits  caused  a shift  from  savings and  money  market
accounts to time deposits.
 
    GOODWILL
 
    Goodwill   and  other  intangibles  amounted   to  $19,177,000,  or  24%  of
stockholders' equity,  at  December 31,  1995.  Goodwill and  other  intangibles
relate  to premiums paid in Pinnacle's  acquisitions. The increase from year-end
1994 was the result of the  acquisition of AFC, where approximately  $13,000,000
in goodwill was recorded.
 
    SHORT-TERM BORROWINGS
 
    Short-term  borrowings are being made on  a day-to-day basis to fund banking
liquidity needs when necessary. There were no short-term borrowings at  December
31, 1995.
 
    NOTES PAYABLE
 
    Pinnacle  had $20,600,000 outstanding in notes payable at December 31, 1995,
compared to $5,400,000  at December  31, 1994. During  1995, Pinnacle  increased
their  borrowings by  $23,000,000 to acquire  AFC. An  additional $8,800,000 was
used for the  repurchase common stock,  the purchase of  equity securities,  and
other  corporate needs. Repayments of $16,600,000  were made from dividends from
subsidiary banks, and sales and dividends  of equity securities. Pinnacle had  a
revolving  line of credit of $7,000,000 at  December 31, 1995, of which $600,000
has been drawn.
 
CAPITAL RESOURCES
 
    Total stockholders' equity of Pinnacle was $78,961,000 at December 31,  1995
up  15% from $68,836,000 at December 31, 1994. The ratio of equity to assets was
9.64% and 10.05% at each year end, respectively.
 
    The  Federal   Reserve  Board   ("Board")  regulations   prescribe   capital
requirements  for bank holding companies. Pinnacle  must have a Leverage Capital
Ratio with  a  minimum level  of  Leverage capital  to  total assets  of  3.00%.
Leverage  capital is the same as Tier One capital, and consists of common stock,
additional paid-in capital and retained earnings, and is exclusive of Pinnacle's
allowance for loan losses, goodwill  and other intangibles, and unrealized  gain
on  securities  available for  sale, net  of tax.  As of  December 31,  1995 and
December 31,  1994, Pinnacle's  Leverage  Capital Ratio  amounted to  6.60%  and
8.54%,  respectively.  In  addition,  the Board  has  issued  Risk-Based Capital
Guidelines with  a minimum  standard  of Tier  One  regulatory capital  to  risk
weighted  assets of 4.00%, and Total (Tier One plus Tier Two) regulatory capital
to risk  weighted assets  of  8.00%. Tier  Two  capital consists  of  Pinnacle's
allowance  for loan losses up to a maximum of 1.25% of risk weighted assets. The
structure of  Pinnacle's balance  sheet results  in a  Risk-Based Capital  Ratio
significantly  in excess of  the guidelines. At December  31, 1995, and December
31, 1994,  Pinnacle's total  risk-based  capital ratio  was 18.09%  and  23.85%,
respectively,  assuming the deduction  of all goodwill  and other intangibles in
compliance with the guidelines.  The reduction in the  total risk based  capital
ratio  was  the result  of  the AFC  acquisition,  where certain  of  the assets
acquired had higher risk weightings.

    In  addition, each of Pinnacle's subsidiary  banks must meet similar minimum
capital requirements  as  prescribed by  Federal  and state  banking  regulatory
authorities. At December 31, 1995, Pinnacle and each of its subsidiary banks was
in compliance with the current capital guidelines.
 
    Book  value per share was $18.05 at  December 31, 1995 compared to $15.62 at
December 31, 1994. During 1995, Pinnacle repurchased 45,755 shares of its common
stock at market prices in privately  negotiated and market transactions as  part
of  its announced  stock repurchase  program. Dividends  amounting to  $1.16 per
share were paid in 1995.
 
LIQUIDITY AND INTEREST RATE SENSITIVITY
 
    Pinnacle's cash flows are comprised of three general types. Cash flows  from
operating  activities  are  primarily  Pinnacle's net  income.  Cash  flows from
investing activities consist of loans made to and collected from customers;  and
purchases,  sales and  maturities of securities  available for  sale. Cash flows
from financing activities  are determined  by Pinnacle's deposit  base and  from
Pinnacle's  ability to borrow and repay debt  and issue or repurchase stock. For
1995, cash flows were generated from a $34,435,000 net decrease in securities, a
$12,458,000  decrease  in  interest-bearing  deposits,  and  a  $15,200,000  net
increase  in notes  payable. Cash flow  uses and needs  included $5,045,000 from
earnings,  an  $18,044,000  decrease  in  deposits,  a  $4,800,000  decrease  in
short-term borrowings, net cash of $14,800,000 to purchase AFC and $6,840,000 to
pay  dividends  and  repurchase  common  stock.  Pinnacle's  net  cash  position
increased $21,108,000 with the majority of the increase in Federal funds sold.
 
    Pinnacle's subsidiary banks have  a relatively stable  base of deposits  and
any  increased loan demand can be  sufficiently funded without a material change
in its balance sheet. Pinnacle's corporate strategy includes acquisitions. These
acquisitions, such  as the  AFC  acquisition, are  primarily funded  with  debt.
Reductions of debt would be made from Pinnacle's earnings. At December 31, 1995,
Pinnacle  had  a  line  of  credit  of  $7,000,000  with  an  unaffiliated bank.
Subsequent to year end, this line of credit was increased to $10,000,000.
 
    Regulatory requirements exist which influence Pinnacle's liquidity and  cash
flow  needs. These requirements include  the maintenance of satisfactory capital
ratios on a consolidated and subsidiary  bank basis, restrictions on the  amount
of  dividends which a subsidiary bank may  pay and reserve requirements with the
Federal Reserve Bank.  Based on  these restrictions,  at January  1, 1996,  bank
subsidiaries  could have declared approximately  $2,715,000 in dividends without
requesting approval of  the applicable  Federal or State  regulatory agency.  In
addition,  Pinnacle has  made loan commitments  which could  result in increased
cash flow  requirements for  loans.  Management is  of  the opinion  that  these
regulatory  requirements and loan commitments will not have a significant impact
on the  liquidity of  Pinnacle. Management  is not  aware of  any known  trends,
events or uncertainties that will have, or that are reasonably likely to have, a
material  effect on Pinnacle. Pending before  Congress is a plan to recapitalize
the SAIF  fund for  thrifts  and banks  which  have "Oakar"  deposits  (deposits
purchased  from  failed  thrift  institutions).  This  plan  includes  potential
one-time charges of $0.85 per $100 of deposits on thrift deposits and $0.66  per
$100  of "Oakar" deposits. After this recapitalization, the insurance rate would
then be the same  rate as now assessed  by the FDIC, which  is currently at  the
minimum  of $2,000 per year for  "well-capitalized" banks. This one-time charge,
anticipated to be levied  in 1996, would cost  the Pinnacle banks  approximately
$1,000,000 on a before tax basis.
 
    Management  had  no  significant  commitments  for  capital  expenditures at
December 31, 1995.

    This  table details Pinnacle's interest rate sensitive position at March 31,
1996. The table is one method of monitoring the interest rate risk of  Pinnacle.
Interest  rate  risk arises  when the  maturity or  repricing of  assets differs
significantly from the maturity or repricing of liabilities.
 
    The table presents a  static gap analysis which  does not fully capture  the
true dynamics of interest rate changes including the timing and/or the degree of
interest  rate changes. Pinnacle analyzes on a continuing basis the effects that
changes in interest rates would have on its interest rate sensitive position and
finds the following gap acceptable in light of its balance sheet mix and current
interest and economic environment.
 
    A ratio greater than 1.00x of earning assets to interest-bearing liabilities
indicates that  an increase  in  interest rates  would  generally result  in  an
increase  in net  income for  Pinnacle. Conversely, a  ratio less  than 1.00x of
earning assets to  interest-bearing liabilities  indicates that  an increase  in
interest  rates would generally result in a decrease in net income for Pinnacle.
Shifts in the structure of interest sensitive assets and liabilities are made by
management in response to interest rate  movements. These changes would be  made
primarily  through the purchase and sale  of securities. All securities owned by
Pinnacle are available for sale and the proceeds from a sale of these securities
could be reinvested in an  alternative maturity range in  order to respond to  a
change  in interest rates. Table 6 includes savings deposits as repricing within
the earliest  period  presented.  Management  believes  that  in  reality  these
deposits  have longer term repricing  characteristics because of the infrequency
of repricing and  because these  deposits are  fairly price  inelastic and  bear
relatively  low interest rates.  If these deposits were  included in the longest
term category,  the  cumulative  ratio of  earning  assets  to  interest-bearing
liabilities  would be 4.39x for 1-90 days;  2.69x for 91-180 days; and 2.12x for
181-365 days.

    Of the loans listed in the maturity schedule above, a total of $193,448  are
due  after one year;  $174,498 of these loans  have predetermined interest rates
and $18,950  of these  loans have  floating interest  rates. There  has been  no
significant  change since  year end  in the  maturity distribution  as disclosed
above.
 
    COLLATERAL AND APPRAISAL GUIDELINES
 
    Subsidiary  banks  of  Pinnacle  make  loans  which  are  collateralized  by
different  types of assets. A collateral  guideline manual is maintained by each
bank which details collateral requirements  for any collateralized loan which  a
bank  may make. The  loan operations area has  responsibility for monitoring all
compliance with collateral  requirements. Collateral requirements  for the  most
commonly funded loans include an 85% - 95% (depending on maturity) loan-to-value
ratio  for loans  secured by  U. S. Government  securities, 70%  for NYSE traded
stock, 65% for AMEX and 50% for  all other common stocks, with the exception  of
control  stocks which  are not  acceptable as  collateral. Commercial  loans for
working capital can have a maximum  loan-to-value ratio of 80% against  eligible
accounts if secured by receivables, a maximum of 50% if secured by inventory and
a  maximum of 80% if secured by equipment.  Real estate loans can have a maximum
loan-to-value ratio of  80% unless  private mortgage insurance  is provided  for
advances  over 80%. Commercial real estate loans typically are funded at a lower
loan-to value ratio and require the personal guarantee of the borrower(s).  Home
equity  loans require a loan-to-value  ratio of 80% of  the appraised value less
any debt.
 
    Loans made by subsidiary banks of Pinnacle which are collateralized by  real
estate  require  an appraisal  prior to  funding  of the  loan. These  loans are
reappraised when management believes that  the financial condition or  resources
of  the borrower have deteriorated or when  the collectibility of the loan is in
question. Loans collateralized by real estate are not necessarily reappraised on
an annual  or quarterly  basis by  policy; however,  all loans  secured by  real
estate,  with immaterial exceptions, are made in the local market area served by
Pinnacle subsidiaries and each of these areas is closely monitored by management
for  economic  changes.  A  new  appraisal  is  required  for  any  loan   which
 
                                       85
<PAGE>
undergoes  foreclosure or is  transferred into other  real estate owned. Updated
appraisals on other real  estate owned are completed  as required by  regulatory
authorities,  or if  management believes  a material  change in  the value  of a
property has taken place.
 
    The current  loan  policies in  effect  for collateral  and  appraisals  are
similar and consistent with the policies in place in prior years.

    A  discussion regarding the  nonperforming assets listed  above is contained
within the section entitled "Management's  Discussion and Analysis of  Financial
Condition and Results of Operations".
 
    Loan Concentrations.  Loan concentrations are defined as amounts loaned to a
multiple  number of borrowers  engaged in similar  activities, which would cause
them to be similarly impacted by economic or other conditions. Although Pinnacle
has a diversified loan portfolio, a substantial natural geographic concentration
of credit risk  exists within  Pinnacle's defined customer  market areas.  These
geographic   market  areas  include  the   Chicago  metropolitan  area  and  the
Quad-Cities metropolitan area of Illinois and Iowa.
 
    Adoption of Statements of Financial Accounting Standards "SFAS" Nos. 114 and
118.  Effective January 1, 1995,  Pinnacle adopted SFAS No. 114, "Accounting  by
Creditors  for Impairment of a Loan", and  its amendment No. 118, "Accounting by
Creditors for Impairment of a Loan -- Income Recognition and Disclosure".  There
was no effect on the financial position and results of operations of Pinnacle as
a  result of adopting  these statements. No changes  were required to Pinnacle's
accounting policies to loans,  charge-offs, and interest income  as a result  of
adopting  these  statements. Loans  considered  impaired under  these statements
include nonaccrual loans, restructured loans,  and loans classified as at  least
doubtful under Pinnacle's credit risk classification system. Total investment in
impaired loans was $5,731,000 at March 31, 1996 which consisted of $3,452,000 in
commercial loans and $2,279,000 in real estate loans. All of Pinnacle's impaired
loans are included in the nonperforming category.
 
    Nonaccrual Loan Policy.  Pinnacle follows banking regulatory guidelines with
respect  to  classifying  loans  on  a nonaccrual  basis.  Loans  are  placed on
nonaccrual when the loan becomes past due over
 
                                       86
<PAGE>
90 days with no intervening activity or when the collection in full of  interest
and  principal is doubtful. Thereafter, no  interest is taken into income unless
received in cash or until such time as the borrower demonstrates the ability  to
pay interest and principal.
 
    Loans  to Affiliates.   Loans are made  in the normal  course of business to
directors, officers and principal holders  of equity securities of Pinnacle  and
its  subsidiary banks.  The terms of  these loans, including  interest rates and
collateral, are similar  to those  prevailing for  comparable transactions  with
others  and do not involve more than a normal risk of collectibility. Changes in
such loans during  the three months  ended March  31, 1996 and  the years  ended
December 31, 1995 and 1994 were as follows:

ALLOCATION OF ALLOWANCE FOR LOAN LOSSES
 
    Pinnacle's subsidiary banks do not allocate the allowance for loan losses by
specific  loan categories. However, bank disclosure guidelines issued by the SEC
request management to allocate the total allowance for loan losses into  certain
categories.  Accordingly, management has allocated the allowance for loan losses
by loan  category based  on historical  charge-off experience  and  management's
evaluation  of potential losses in the  loan portfolio. The specific allocations
are not intended to be indicative of future charge-offs. The unallocated portion
of the allowance for loan losses represents
 
                                       88
<PAGE>
that portion of the allowance which  has not been specifically allocated by  the
analysis performed. The percent of loans in each category to total loans and the
allocation of the allowance for loan losses at March 31, 1996 and December 31 of
each year, in thousands, is as follows:

    Management  believes that the portfolio is  well diversified and, to a large
extent, secured without undue concentrations in any specific risk area.  Control
of  loan quality is continually monitored  by management. Management's system of
review of the loan portfolio and the attendant determination of the adequacy  of
the  allowance for  loan losses  is made  up of  a number  of factors.  The most
significant part of  the system is  the independent credit  review system  which
reviews  all commercial  credits in excess  of $100,000 and  all commercial real
estate credits in  excess of  $250,000 on  an annual  basis at  a minimum,  with
problem  credits  reviewed  more  often as  necessary.  An  informed, judgmental
determination is made of the risk associated with loans which have received  low
grades under the credit review system. This estimated risk is taken into account
in  determining  the  allowance  for loan  losses.  In  addition,  the allowance
includes a substantial reserve for coverage of unidentified risks.
 
    In addition to the  credit review system, on  a quarterly basis an  internal
report  provides an analysis of the adequacy of the allowance for management and
the Board  of Directors.  This analysis  focuses on  allocations based  on  loan
review  ratings  and historical  charge-off and  recovery data.  Management also
reviews the status of all watch list credits on a monthly basis. The process and
the amount of the allowance and of  the provision have also been subject to  the
review  of external auditors and  banking regulatory authorities, and management
believes  that  it  has  an   effective  system  of  credit  review   assessment
demonstrated  by the fact that Pinnacle has not recorded a significant loss that
had not been previously  identified as a  watch list credit  by the loan  review
process.

                         BUSINESS OF FINANCIAL SECURITY
 
    Financial  Security Corp. was incorporated under Delaware law in July, 1991.
On December 29, 1992, Financial Security acquired Security Federal, as a part of
Security  Federal's  conversion  from  a  federally  chartered  mutual   savings
association  to  a  federally  chartered  stock  savings  association. Financial
Security is a savings and loan holding  company and is subject to regulation  by
the  OTS, the FDIC and the SEC.  Currently, Financial Security does not transact
any material business other  than through its  subsidiary, Security Federal.  At
March   31,  1996,   Financial  Security   had  total   consolidated  assets  of
$273,965,000, total loans of $188,219,000, including loans held for sale,  total
deposits of $188,777,000 and total stockholders equity of $39,372,000.
 
    Security Federal was organized in 1907 as a federally chartered building and
loan  association. In 1937, Security Federal  converted to a federally chartered
savings and loan association. Security Federal  is a member of the federal  home
loan  bank system, and its deposit accounts are insured to the maximum allowable
amount by the FDIC. Security Federal  conducts business through its two  offices
which  are located in Chicago and  Niles, Illinois. Security Federal's principal
business has  been and  continues  to be  attracting  retail deposits  from  the
general public, and investing those deposits, together with funds generated from
operations  and borrowings, primarily in one-to-four family residential mortgage
loans  and,  to  a  lesser  extent,  multi-family  residential  mortgage  loans,
mortgage-backed securities, purchased mortgage servicing rights, U.S. Government
and federal agency securities, and other investment securities.

FINANCIAL SECURITY'S MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS
 
COMPARISON OF FINANCIAL CONDITION AND OPERATING RESULTS FOR THREE MONTHS ENDED
MARCH 31, 1996 AND 1995
 
GENERAL
 
    Financial Security's results of operations are primarily dependent upon  its
net   interest  income  which   is  the  difference   between  interest  on  its
interest-earning  assets,  such   as  loans,   mortgage-backed  securities   and
investment  securities, and  interest paid on  its interest-bearing liabilities,
such as deposits and borrowings. Net interest income is directly affected by the
relative amounts of interest-earning assets and interest-bearing liabilities and
the interest rates earned or paid on such amounts. Financial Security's  results
of  operations are also affected by the  provision for loan losses and the level
of non-interest income and expenses. Non-interest income includes  transactional
fees,  loan servicing  fees, fees on  purchased mortgage  servicing rights, real
estate operations and fees and commissions from the sales of insurance  products
through  its operating  subsidiary. Non-interest  expenses primarily  consist of
salaries and employee  benefits, occupancy expenses,  federal deposit  insurance
premiums and other operating expenses.
 
    The  operating results of Financial Security are also significantly affected
by general economic and competitive conditions, the monetary and fiscal policies
of federal  agencies  and  the  policies of  agencies  that  regulate  financial
institutions.  The cost  of funds is  influenced by interest  rates on competing
investments and  general  market  rates  of  interest.  Lending  activities  are
influenced  by the demand for real estate  loans and other types of loans, which
is in turn affected by the interest rates at which such loans are made.  General
economic  conditions affect  the loan demand  and the availability  of funds for
lending activities.
 
    During the first quarter of 1996, the yields on long-term investments  (such
as  mortgage loans and U.S. Treasury bonds) have increased moderately, while the
yields on short-term  investments have  remained relatively  stable. During  the
first  quarter, Financial Security's yield  on interest earning assets decreased
from 8.16% to 8.02% and the cost  of funds decreased from 5.38% for fiscal  1995
to  5.27% due to a reduction in deposit  rates from 5.10% to 4.97% and borrowing
costs from 6.87% to 6.79%  which resulted in a net  interest margin of 3.31%  as
compared to 3.30% at year end 1995.
 
LIQUIDITY & CAPITAL RESOURCES
 
    Financial Security's primary sources of funds are deposits and proceeds from
principal  and  interest  payments  on  loans.  While  maturities  and scheduled
amortization of  loans are  a predictable  source of  funds, deposit  flows  and
mortgage  prepayments are greatly  influenced by interest  rate cycles, economic
conditions and competition.
 
    Liquidity management for Financial  Security is both  a daily and  long-term
function  of  management's  strategy.  Financial  Security's  subsidiary  thrift
association is required to maintain  minimum levels of qualifying liquid  assets
which  are defined by OTS regulations. This  requirement, which may be varied at
the direction of the OTS depending  upon economic conditions and deposit  flows,
is  based upon  percentage of deposits  and short-term  borrowings. The required
ratio is currently 5.0%. At March  31, 1996, Security Federal's liquidity  ratio
was 6.2%.
 
    Financial   Security   continues   to  maintain   adequate   liquidity  with
approximately $10.3 million held in cash and cash equivalents and $56.9  million
in  investments  classified as  available-for-sale  and loans  classified  as or
held-for-sale at March 31, 1996.  If necessary, Security Federal has  additional
secured  borrowing ability with the Federal  Home Loan Bank of Chicago. Security
Federal will continue to use advances from the Federal Home Loan Bank-Chicago if
they prove to be a less costly source of funds or can be invested at a  positive
rate of return.
 
                                       91
<PAGE>
    Management's  interest rate  sensitivity strategy  is designed  to provide a
relatively stable stream of net  interest income in moderately varying  interest
rate  environments. Having relatively high levels of cash, cash equivalents, and
short to intermediate term securities helps achieve this objective.
 
    Financial Security's cash flows are comprised of three classifications: cash
flows from operating activities, cash flows from investing activities, and  cash
flows   from  financing  activities.  Cash   flows  from  operating  activities,
consisting primarily of interest and  dividends received; less interest paid  on
deposits,  were $3.3 million for the three months ended March 31, 1996. Net cash
provided by investing  activities was $2.3  million for the  three months  ended
March  31,  1996.  Disbursements  for loan  originations,  and  the  purchase of
investments available  for sale  totaled  $12.9 million,  these were  offset  by
principal  collected  on  loans,  mortgage-backed  securities,  and  maturity of
securities totaling  $14.5  million.  Net  cash  used  in  financing  activities
amounted to $3.5 million for the three months ended March 31, 1996.
 
    At  March  31,  1996,  Financial  Security  had  outstanding  commitments of
$949,000, all of which were fixed rate  loans, with rates ranging from 6.25%  to
10.50%.  In addition,  Financial Security  had $1.0  million in  unused lines of
credit under its home  equity loan program. The  weighted average rate on  those
lines  is 9.44%.  Financial Security  anticipates that  it will  have sufficient
funds available  to  meet  its  current  commitments.  Certificates  of  deposit
scheduled  to mature  in one  year or  less from  March 31,  1996, totaled $91.6
million. Management believes that  a significant portion  of such deposits  will
remain  with Financial Security  and that their maturity  and repricing will not
have a material adverse impact.
 
    The current FHLB-Chicago  advances mature on  a tiered basis  over the  next
four  years. Management intends to monitor these advances during their terms and
repay or renegotiate such advances as required.
 
CHANGES IN FINANCIAL CONDITION FOR THE THREE MONTHS ENDED MARCH 31, 1996
 
    TOTAL ASSETS
 
    Total assets as of March 31, 1996, amounted to $274.0 million as compared to
$277.1 million at December 31, 1995, a  decrease of $3.1 million or 1.1%.  Total
loans  as of March 31,  1996, including loans held  for sale, amounted to $188.2
million as compared to $194.0 million at  December 31, 1995, a decrease of  $5.8
million  or 3.0%. The decrease in loans  resulted from a decrease in loan demand
and the sales of $1.7 million from loans held-for-sale. During the three  months
ended  March 31,  1996, Financial Security  originated $1.4 million  in loans as
compared to $5.2 million in the  comparable period in 1995, while loan  payments
increased  from $4.4 million in  1995 to $5.0 million  in 1996. Total securities
amounted to $56.5 million as of March 31, 1996, as compared to $55.5 million  in
1995, an increase of $1,000,000 or 1.8%.
 
    TOTAL DEPOSITS
 
    Total  deposits at March 31, 1996, amounted to $188.8 million as compared to
$193.8 million at  December 31,  1995, a  decrease of  $5 million  or 2.6%.  The
decrease  in deposits is due mainly to  a decrease in certificates of deposit at
the Niles office from $16.6 million to $12.3 million. Advances from the  Federal
Home  Loan Bank increased $2.8 million from $38.7 at December 31, 1995, to $41.5
million at March 31, 1996, while the weighted average rate decreased from  6.66%
at December 31, 1995, to 6.48% at March 31, 1996.
 
    STOCKHOLDERS' EQUITY
 
    Stockholders'  equity  at  March  31, 1996,  amounted  to  $39.4  million as
compared to $38.8 million as of December 31, 1995, an increase of $600,000. This
increase was  due to  net income  of  $548,000, proceeds  from the  exercise  of
employee  stock options of $344,000 and  contributions and vesting of employment
benefit plans of $79,000 which was partially offset by a net decrease in  market
value of the available-for-sale portfolio of $366,000. As of March 31, 1996, the
book value per outstanding
 
                                       92
<PAGE>
share of common stock was $25.85 as compared to $25.92 at December 31, 1995. The
primary  reasons for this decrease were  the exercise of shareholder options and
the fluctuation in the market value of the available-for-sale portfolio.
 
    The OTS has established three capital standards for thrifts:
 
    - Tangible capital ratio equal to 1.5% of adjusted total assets
 
    - Core capital ratio equal to 3.0% of adjusted total assets
 
    - Risk-based ratio equal to 8.0% of risk weighted assets
 
Financial Security's  subsidiary significantly  exceeds each  of the  regulatory
capital  requirements at March 31, 1996. The following table represents Security
Federal's capital ratios:

    The OTS  issued  final  regulations  which set  forth  the  methodology  for
calculating  an interest rate-risk  component that is  being incorporated in the
OTS  regulatory  capital  rules.  Under   the  new  regulations,  only   savings
institutions  with "above  normal" interest  rate-risk exposure  are required to
maintain additional  capital.  The  OTS  has  deferred  implementation  of  this
regulation.  As  of March  31, 1996,  Security  Federal was  not subject  to any
interest rate-risk component.
 
    NON PERFORMING ASSETS
 
    Non-performing assets at March 31, 1996, amounted to $7.0 million or 2.6% of
total assets as compared  to $5.5 million  or 2.0% at  December 31, 1995.  Total
non-performing  loans and leases amounted to $5.7 million or 3.0% of total loans
as compared to 2.1% as of December 31, 1995. The primary reason for the increase
in non-performing loans  and assets  is the commercial  office equipment  leases
purchased  from Bennett Funding Group, Inc., totaling $1.6 million. On March 28,
1996, the U.S. Attorney's  office in New York  City charged Patrick Bennett  and
Bennett  Funding Group, Inc., a Syracuse  NY company ("Bennett") with securities
fraud and perjuring in connection with  Bennett's offering of up to $80  million
in  short-and-medium-term notes.  In addition,  the SEC  filed suit  against Mr.
Bennett and his related companies. On  April 1, 1996, Bennett filed for  Chapter
11  bankruptcy protection and ceased payments to investors. It is uncertain what
effect, if  any,  the  Bennett  litigation  will  have  on  Financial  Security.
Therefore  Financial Security  has classified  the leases  as non-performing and
placed them  on  non-accrual status.  The  lease payments  are  currently  being
received  by the bankruptcy  trustee. It is  anticipated that Financial Security
will experience a temporary  loss of interest  on the leases  until they can  be
transferred  from  the trustee  to Security  Federal. However,  there can  be no
assurance the  additional  losses  will  not be  incurred  due  to  the  pending
litigation against Bennett.
 
COMPARISON OF OPERATING RESULTS FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND
1995
 
    INTEREST INCOME
 
    Interest  income for the three months ended March 31, 1996, amounted to $5.1
million as  compared to  $5.0 million  for  the comparable  period in  1995,  an
increase  of $.1 million or 2.0%. This  increase was attributable primarily to a
decrease in the average  balances outstanding on  interest earning assets  which
was offset by an increase in the annualized yield from 7.56% in 1995 to 8.02% in
1996.
 
                                       93
<PAGE>
    INTEREST EXPENSE
 
    Interest expense for the three months ended March 31, 1996, amounted to $3.0
million  compared to 2.9 million for the  comparable period in 1995, an increase
of $40,000 or 1.4%. This increase was  due primarily to increased cost of  funds
from  5.13% for the quarter  ended March 31, 1995, as  compared to 5.27% for the
comparable period in 1996.
 
    NET INTEREST
 
    Net interest income for the three  months ended March 31, 1996, amounted  to
$2.1  million, an increase of $41,000 or  .02% over 1995. Net interest margin at
March 31, 1996, amounted to  3.31% as compared to 2.92%  at March 31, 1995.  The
effect  of the  increase in rates  was offset by  decreased balances outstanding
during the quarter.
 
    PROVISION FOR LOAN LOSSES
 
    Provision for loan losses was $75,000 for the quarter ended March 31,  1996,
due  to the  Bennett leases. While  management believes that  its allowances for
losses are at an adequate level, there can be no assurance that losses will  not
exceed  estimated  amounts. Management  continues  to monitor  the  allowance in
relation to the performance of Financial Security's loan portfolio, the  economy
and changes in real estate values. (See "Non-Performing Assets" above.)
 
    NON-INTEREST INCOME
 
    Non-interest  income for the three months  ended March 31, 1996, amounted to
$484,000 as compared to $317,000 for the comparable period in 1995, an  increase
of  $167,000 or  52.7%. This  increase was  primarily attributable  to increased
gains on sale of assets of $103,000 and increased income from purchased mortgage
servicing rights of $43,000.
 
    NON-INTEREST EXPENSE
 
    Non-interest expense for  the three months  ended March 31,  1996, was  $1.8
million as compared to $1.7 million for the three months ended March 31, 1995 as
cost  reductions in occupancy, data processing, legal fees, and advertising were
offset by increases in compensation, federal deposit insurance premiums, loss on
R.E.O. operations and provision for losses on securities.
 
    INCOME TAX EXPENSE
 
    Income tax expense for  the three months ended  March 31, 1996, amounted  to
$188,000 as compared to $54,000 for the comparable period in 1995. This increase
was  primarily due to increased pre-tax income for the first quarter of 1996 and
tax credits pertaining to  a low income housing  project which were recorded  in
the first quarter of 1995.
 
COMPARISON OF FINANCIAL CONDITION AND OPERATING RESULTS FOR THE YEARS ENDED
DECEMBER 31, 1995, 1994 AND 1993
 
GENERAL
 
    Financial Security is a Chicago based thrift holding company which completed
its  initial public offering  on December 29, 1992,  along with the simultaneous
conversion of its only subsidiary, Security Federal Savings and Loan Association
of Chicago from a federally chartered mutual savings association to a  federally
chartered  stock savings association.  Although Security Federal  is primarily a
local lender, Security Federal has a substantial concentration of  out-of-market
purchased  and participation  loans (see  Note 4  to the  Consolidated Financial
Statements for the Year Ended December 31, 1995 regarding these concentrations.)
On November 10, 1994, Security Federal opened its first branch office at 5697 W.
Touhy Avenue, Niles, Illinois in order to better serve its customer base and tap
into new deposit and lending  markets. As of December  31, 1995 deposits at  the
Niles Branch totaled $17.0 million.
 
                                       94
<PAGE>
    On  January 5, 1995, Financial Security  announced its intention to continue
its stock repurchase  program by purchasing  an additional five  percent of  its
outstanding  shares in  the open market.  The third repurchase  was completed on
March 10, 1995 and a total of 78,456 shares were repurchased at an average price
of $17.73 per share.
 
    Financial Security  conducts  no  significant business  other  than  holding
investment  securities. All  references to  Financial Security  include Security
Federal and  its subsidiary,  Security Federal  Service Corp.  unless  otherwise
indicated,  except that references  to Financial Security  prior to December 29,
1992, are to Security Federal and its subsidiary on a consolidated basis.
 
    Financial Security's results  of operations are  primarily dependent on  net
interest  income which  is the difference  between interest income  on its loan,
mortgage backed  securities and  investment portfolios  and its  cost of  funds,
consisting of interest paid on deposits and borrowed funds. Financial Security's
operating  expenses  principally  consist  of  employee  compensation, occupancy
expense,  federal  insurance  premiums  and  other  general  and  administrative
expenses.  Financial Security's results of operations are significantly affected
by general  economic  competitive  conditions, particularly  changes  in  market
interest rates, government policies and actions of regulatory authorities.
 
RECAPITALIZATION OF THE SAVINGS ASSOCIATION INSURANCE FUND
 
    Security Federal's deposits are insured by the Savings Association Insurance
Fund  (the "SAIF") of  the FDIC. The  ratio of the  SAIF's insurance reserves to
total SAIF-insured  deposits remains  below the  statutorily designated  reserve
ratio  of 1.25%. Legislation pending before  the Congress would recapitalize the
SAIF to the designated reserve ratio by imposing a special assessment, of 85  to
90  basis points on total deposits, against SAIF-insured institutions. Financial
Security is presently unable to determine  the amount of any special  assessment
Security  Federal will be  required to pay.  It is anticipated  that the special
assessment will  have  to  be paid  in  a  lump sum,  rather  than  in  periodic
installments,  and is, therefore, likely to have  a major one-time impact on the
earnings of Security Federal.
 
    In  addition,  other  pending  legislation  includes  the  requirement  that
federally  chartered  thrifts  convert  to  national  banks  or  state chartered
institutions, which may restrict future  joint venture development projects,  as
well  as recapturing a  portion of bad debt  reserves. Management cannot predict
the ultimate impact the  final legislation and regulatory  actions will have  on
Financial Security and its operations.
 
RECENT AND PROPOSED CHANGES IN ACCOUNTING RULES
 
    STATEMENT    OF    FINANCIAL   ACCOUNTING    STANDARDS   NO.    114   ("SFAS
114").  "Accounting  by Creditors  for Impairment of  a Loan"  is effective  for
fiscal  years beginning after December 15, 1994. Financial Security adopted SFAS
114 on January 1, 1995. The adoption of SFAS 114 did not have a material  impact
on Financial Security's earnings or financial condition.
 
    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 115 ("SFAS 115").  Effective
January  1,  1994,  Financial  Security  adopted  the  provisions  of  SFAS 115,
"Accounting for Certain  Investments in  Debt and Equity  Securities". SFAS  115
requires corporations to classify securities as either held-to-maturity, trading
or  available-for-sale. In the fourth quarter  of 1995, the Financial Accounting
Standards Board announced that they would grant institutions, such as  Financial
Security,  a one-time  opportunity to  reclassify securities  when it  issued "A
Guide to  Implementation  of Statement  115".  Under this  provision,  Financial
Security  could reclassify securities from "held-to-maturity" without "tainting"
the rest of  the portfolio.  In December, 1995,  Financial Security  transferred
$24.6  million  of its  investment  securities and  mortgage-backed  and related
securities from  held-to-maturity  to available-for-sale.  This  transfer  gives
Financial Security greater flexibility in administering its portfolio.
 
    STATEMENT  OF FIANNCIAL ACCOUNTING  STANDARDS NO. 122 ("SFAS  122").  On May
12, 1995,  the  Financial  Accounting  Standards Board  issued  SFAS  122.  This
statement  provides for capitalization of  Mortgage Servicing Rights (MSRs) when
mortgage loans (whether originated or purchased) are subsequently sold with  the
MSRs   retained.  This  statement  applies   to  MSRs  resulting  from  mortgage
 
                                       95
<PAGE>
loans only, and will be effective for fiscal years beginning after December  15,
1995.  Management  believes  that SFAS  122  will  not have  material  impact on
Financial Security's earnings or financial condition.
 
    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS BOARD NO. 123 ("SFAS 123").   In
October  of  1995, the  Financial Accounting  Standards  Board issued  SFAS 123,
"Accounting for Stock Based Compensation". SFAS 123 encourages entities to use a
fair value based method to account for stock based compensation plans. If such a
fair value method is not adopted, entities must disclose the proforma effect  on
net  income and on  earnings per share  had the accounting  method been adopted.
This statement applies to  years beginning after  December 15, 1995.  Management
does  not believe that this statement will have a material effect on earnings or
the financial position of Financial Security.
 
COMPARISON OF OPERATING RESULTS FOR THE YEARS ENDED DECEMBER 31, 1995 AND
DECEMBER 31, 1994
 
    GENERAL
 
    Financial Security recorded net income of $2.1 million, or $1.35 per primary
share, for the fiscal year ended December  31, 1995 compared to $1.9 million  or
$1.17  per primary share for fiscal 1994, an increase of $200,000 or 10.53%. The
increase in net  income was  due primarily  to increased  noninterest income  of
$901,000,  decreased  legal fees  of  $133,000, decreased  professional  fees of
$178,000 and decreased income tax expense of $502,000 which was partially offset
by a decrease in net interest income of $1.4 million.
 
    INTEREST INCOME
 
    Interest income for  1995 amounted  to $21.2  million as  compared to  $19.6
million  for  1994, an  increase of  $1.6  million or  8.16%. This  increase was
attributable primarily to an increase  in the average yield on  interest-earning
assets  from  7.83% at  December  31, 1994  to 8.16%  at  December 31,  1995 and
increased average balances outstanding from $251.0 million at December 31,  1994
to $260.2 million at December 31, 1995.
 
    INTEREST EXPENSE
 
    Interest  expense for  1995 amounted  to $12.7  million as  compared to $9.6
million for 1994, an increase of $3.1  million or 32.29%. This increase was  due
to  an  increase in  average deposits  in  1995 of  $13.2 million  and increased
average borrowings of $3.3  million, along with an  increase in average cost  of
funds  from 4.40%  for the year  ended December 31,  1994 to 5.38%  for the year
ended December 31, 1995.
 
    PROVISION FOR LOAN LOSSES
 
    For fiscal 1995  total provision  for loan  losses amounted  to $100,000  as
compared  to $200,000  for fiscal  1994, a decrease  of $100,000  or 50.0%. This
decrease in  the  provision reflects  continued  improvements in  the  level  of
non-performing  loans  which  decreased to  $4.0  million from  $6.6  million, a
reduction of $2.6 million or 39.4%. While management believes its allowances for
losses are  adequate, there  can be  no assurance  that losses  will not  exceed
estimated  amounts. Management continues to monitor the allowance in relation to
the performance of Financial Security's loan portfolio, the economy and  changes
in real estate values.
 
    NET INTEREST INCOME AFTER PROVISION FOR LOAN LOSSES
 
    Net  interest income for fiscal 1995 amounted to $8.5 million as compared to
$9.8 million  for fiscal  1994, a  decrease of  $1.3 million  or 13.27%.  During
fiscal  1995 the average  yield on interest earning  assets increased from 7.83%
for the year ended December  31, 1994 to 8.16% for  the year ended December  31,
1995 while the average rate on interest bearing liabilities increased from 4.40%
for  the year ended December  31, 1994 to 5.38% for  the year ended December 31,
1995. This resulted in a reduction in the net interest margin from 3.99% for the
year ended December 31, 1994 to 3.30% for the year ended December 31, 1995.
 
                                       96
<PAGE>
    NONINTEREST INCOME
 
    Noninterest income for fiscal 1995 amounted  to $1.1 million as compared  to
$.2  million for fiscal 1994, an increase of $900,000 or 450.0%. The reasons for
this increase was  increased income  on purchased mortgage  servicing rights  of
$532,000  and profits  on sale  of loans  and securities  available for  sale of
$229,000 as compared to losses recorded in 1994 of $132,000.
 
    NONINTEREST EXPENSE
 
    Noninterest expense for fiscal 1995 amounted to $7.0 million as compared  to
$7.2  million for fiscal 1994, a decrease of $200,000 or 2.78%. This decrease is
primarily due to  reductions in legal  fees of $133,000  and other  professional
fees  of $178,000 and a decrease in  the provision for foreclosed real estate of
$500,000 offset  by an  increase in  the  provision for  loss on  securities  of
$483,000  (see  Changes  in  Financial  Condition,  non-performing  assets)  and
moderate increases in other operating expenses.
 
    INCOME TAX EXPENSE
 
    Income tax expense for 1995 amounted to $468,000 as compared to $970,000 for
1994, a decrease of $502,000. This decrease was due primarily to the tax  effect
of  credits  related to  a  low-income housing  project  and a  reversal  of the
valuation allowance for various deferred tax assets.
 
COMPARISON OF OPERATING RESULTS FOR THE YEARS ENDED DECEMBER 31, 1994 AND
DECEMBER 31, 1993.
 
    GENERAL
 
    Financial Security recorded net income of $1.9 million, or $1.17 per  share,
for  the fiscal year ended  December 31, 1994 compared  to $2.4 million or $1.40
per share before the effect of a change in accounting for income taxes in  1993,
a  decrease of $0.23 or  16.4%. The decrease in net  income before the change in
accounting for income taxes was primarily due to a decrease in gains on sale  of
securities  of $482,000  and increased interest  expense of  $908,000, which was
partially offset  by decreases  in provision  of loan  losses of  $372,000,  non
interest expense of $98,000 and income tax expense of $430,000.
 
    INTEREST INCOME
 
    Interest  income for  1994 amounted  to $19.6  million as  compared to $19.7
million for 1993, a  decrease of $44,000  or 0.5%. The  decrease was the  direct
result of lower yields on loan and investments which were partially offset by an
increase  in the average balance of interest  earning assets of $17.9 million or
7.7%. The yield on average earning assets was 7.83% in 1994 as compared to 8.45%
in 1993.
 
    INTEREST EXPENSE
 
    Interest expense  for 1994  amounted to  $9.6 million  as compared  to  $8.7
million  for 1993, an  increase of $908,000  or 10.3%. During  1994, interest on
borrowings increased $1.2 million while interest on deposits decreased $335,000.
The average costs  of deposits decreased  .10% from  4.34% in 1993  to 4.24%  in
1994,  while the average  cost of borrowed  funds increased 1.08%  from 4.59% in
1993 to 5.67% in 1994.
 
    PROVISION FOR LOAN LOSSES
 
    Provision for loan  losses for  1994, amounted  to $200,000  as compared  to
$572,000  for 1993, a decrease of $372,000  or 67.0%. The decreased in the level
of loan loss  provision reflects  the continued decrease  in nonperforming  loan
balances  during 1994 ($6.5 million  or 3.2% of total  loans as compared to $7.7
million or 3.9% at December  31, 1993 and $9.6 million  or 5.7% at December  31,
1992.) During this two year period loan loss reserves have increased to 50.0% of
nonperforming loans at December 31, 1994 from 49.25% at December 31, 1993.
 
    NONINTEREST INCOME
 
    Noninterest income for 1994 amounted to $240,000 as compared to $688,000 for
1993,  a  decrease of  $448,000 or  65.1%.  This decrease  was due  primarily to
decreases in gains on sales of investments of
 
                                       97
<PAGE>
$482,000  and  other  non-operating  income  of  $113,000,  (1993  included   an
out-of-court  settlement of a law suit of $133,000), which were partially offset
by new income of $136,000 from purchased mortgage servicing rights.
 
    NONINTEREST EXPENSE
 
    Total noninterest expense for 1994 amounted  to $7.2 million as compared  to
$7.3  million for 1993, a  decrease of $100,000 or  1.4%. Increases in occupancy
expense of  $52,000,  deposit  insurance  premiums of  $38,000,  legal  fees  of
$65,000,  provision for  loss on  foreclosed real  estate of  $149,000 and other
operating expense  of $339,000  were  offset by  decreases in  compensation  and
benefits  of $37,000, loss from foreclosed real estate operations of $43,000 and
provision for loss from investments of $595,000. Financial Security continues to
account for its  impaired CMOs on  a cost  recovery basis and  its impaired  FHA
Title  1 participations on a  cash basis. During 1994,  provisions for losses on
these investments  amounted to  $410,000,  and allowances  for losses  on  these
securities amounted to $1.3 million at December 31, 1994.
 
    INCOME TAX EXPENSE
 
    Federal and state income tax expense decreased $430,000 or 30.7% to $970,000
for  1994 as compared to $1.4 million for  1993. Income tax expense as a percent
of pretax earnings was 33.7% in 1994 and 36.8% in 1993. The primary reasons  for
the  decreased effective tax rate  when compared to statutory  rates were due to
significantly higher  interest  earned on  Federal  Agency securities  which  is
nontaxable  for  state income  tax purposes,  and  a new  tax credit  of $95,000
received on a low income housing project.
 
CHANGES IN FINANCIAL CONDITION FOR THE YEAR ENDED DECEMBER 31, 1995
 
    TOTAL ASSETS
 
    As of December 31, 1995, total assets amounted to $277.1 million as compared
to $272.4 million at December  31, 1994, an increase  of $4.7 million or  1.73%.
Total  loans as of December 31, 1995, including loans held for sale, amounted to
$194.0 million as compared to $205.6 million at December 31, 1994, a decrease of
$11.6 million or 5.6%,  due to decreased loan  demand and reallocation of  funds
into  purchased mortgage  servicing rights. During  the year  ended December 31,
1995, Financial Security originated $21.6 million in loans as compared to  $23.1
million during 1994. Total investment securities amounted to $55.5 million as of
December 31, 1995 as compared to $39.9 million at December 31, 1994, an increase
of  $15.6  million or  39.1%  primarily in  intermediate  to long  term callable
federal agency securities, and was funded primarily by the increase in  deposits
and repayments on loans.
 
    TOTAL DEPOSITS
 
    As  of  December 31,  1995,  total deposits  amounted  to $193.8  million as
compared to $186.6 million as of December 31, 1994, an increase of $7.2  million
or  3.9%.  The increase  in  deposits is  primarily  the result  of  an expanded
customer base due to the operation of our Niles, Illinois office which grew from
$0.5 million at December 31, 1994 to $17.0 million as of December 31, 1995.  The
proceeds  of these deposits were used  to reduce reliance on jumbo certificates,
repay  FHLB  advances  and  invested  in  intermediate  to  long-term   callable
securities.
 
    STOCKHOLDERS' EQUITY
 
    At  December 31,  1995, stockholders'  equity amounted  to $38.8  million as
compared to $38.7 million as of December 31, 1994, an increase of $100,000. This
increase was due to the payment of $1.6 million in dividends and the third stock
repurchase of $1.4 million during the  first quarter of 1995; which were  offset
by  earnings of $2.1 million during 1995, a recovery of net unrealized losses of
$315,000  on  available-for-sale   securities  and  net   unrealized  gains   on
available-for-sale securities of $173,000 in 1995. As of December 31, 1995, book
value  per share of common stock was $25.92 as compared to $24.70 as of December
31, 1994.

    NON-PERFORMING ASSETS
 
    At December 31, 1995, non-performing assets amounted to $5.5 million or 2.0%
of total assets, as  compared to $10.4  million or 3.81% of  total assets as  of
December 31, 1994, a decrease of $4.9 million or 47.1%. The largest component of
non-performing  assets was in non-accruing classified  loans ninety days or more
delinquent  totaling  $4.0  million,  composed  primarily  of  1  to  4   family
residential  mortgages.  The  remainder of  Financial  Security's non-performing
assets is  in  foreclosed real  estate,  consisting  of 17  properties  with  an
aggregate   carrying  value   of  $1.3  million   and  defaulted   FHA  Title  I
Collateralized Mortgage Obligations with a net carrying value of $270,000.
 
    Financial Security's  investment in  the defaulted  collateralized  mortgage
obligations  (CMO) is net  of a specific  reserve of $1,643,171  and $969,330 at
December 31,  1995  and 1994,  respectively.  Financial Security's  Tranche  "B"
investment  is subordinate to  Tranche "A". The reserve  has been established by
management to cover  estimated losses. In  May of 1995,  interest payments  were
discountined  by  the servicer.  This  investment has  no  liquid market  and is
impaired due to high delinquency and  loss rates. Management has been unable  to
get  any information as to the remaining value of these securities. In 1995, the
reserve was increased by $674,000.
 
LIQUIDITY & CAPITAL RESOURCES
 
    Financial Security's primary sources of funds are deposits and proceeds from
principal and  interest  payments  on  loans.  While  maturities  and  scheduled
amortization  of  loans  are predictable  sources  of funds,  deposit  flows and
mortgage prepayments are  greatly influenced by  interest rate cycles,  economic
conditions and competition.
 
    Liquidity  management for Financial  Security is both  a daily and long-term
function  of  management's  strategy.  Financial  Security's  subsidiary  thrift
association  is required to maintain minimum  levels of qualifying liquid assets
which are defined by OTS regulations.  This requirement, which may be varied  at
the  direction of the OTS depending  upon economic conditions and deposit flows,
is based upon  percentage of  deposits and short-term  borrowings. The  required
ratio is currently 5.0%. At December 31, 1995 Security Federal's liquidity ratio
was 5.8%
 
    Financial   Security   continues   to  maintain   adequate   liquidity  with
approximately $8.2 million held in cash or overnight funds and $57.6 million  in
investments  and loans classified as  available-for-sale. If necessary, Security
Federal has additional secured borrowing ability with the Federal Home Loan Bank
of Chicago. Security Federal will continue to use advances from the Federal Home
Loan Bank of Chicago if they continue to be a less costly source of funds or can
be invested at a positive rate of return.
 
    Management's interest rate  sensitivity strategy  is designed  to provide  a
relatively  stable stream of net interest  income in moderately varying interest
rate environments. Having relatively high levels of cash, cash equivalents,  and
short to intermediate term securities helps achieve this objective.
 
    Financial Security's cash flows are comprised of three classifications: cash
flows  from operating activities, cash flows from investing activities, and cash
flows  from  financing  activities.   Cash  flows  from  operating   activities,
consisting  primarily of interest and dividends  received, less interest paid on
deposits, were $6.1 million for the year ended December 31, 1995. Net cash  used
in  investing activities was $4.1 million for  the year ended December 31, 1995.
Disbursements for  loan  originations, purchase  of  loans receivable,  and  the
purchase  of investments  available for sale  totaled $58.9  million, these were
partially offset by  principal collected on  loans, mortgage-backed  securities,
and sales and maturities of securities totaling $52.1 million. Net cash provided
by  financing activities  amounted to  $33,000 for  the year  ended December 31,
1995. Receipt of $7.3 million in deposits was offset by the completion of a $1.4
million repurchase program, the payment of a special dividend to shareholders of
$1.6 million and the net repayment of $3.1 million borrowed funds.
 
    At December  31, 1995,  Financial Security  had outstanding  commitments  of
$863,000,  all of which were fixed rate  loans, with rates ranging from 7.00% to
9.00%. In addition, Financial  Security had $870,000 in  unused lines of  credit
under   its   home  equity   loan  program.   The   weighted  average   rate  on
 
                                       99
<PAGE>
those  lines  is  9.66%.  Financial  Security  anticipates  that  it  will  have
sufficient  funds  available to  meet its  current commitments.  Certificates of
deposit scheduled to mature in one year  or less from December 31, 1995  totaled
$89.9  million. Management believes that a  significant portion of such deposits
will remain with Financial Security and  that their maturity and repricing  will
not have a material adverse impact.
 
    The  current FHLB of Chicago advances mature on a tiered basis over the next
four years. Management intends to monitor these advances during their terms  and
repay or negotiate such advances as required.
 
CAPITAL RESOURCES
 
    The  OTS requires that Security Federal maintain specified levels of capital
pursuant to its regulations. At December 31, 1995, Security Federal had tangible
capital of  $30.0 million,  or 11.15%  of total  assets, core  capital of  $29.1
million  or 10.85% of  total assets, which  are $25.9 million  and $21.0 million
above the minimum requirements of 1.5%  and 3.0%, respectively. On December  31,
1995,  Security Federal had risk-based capital of $30.5 million (including $29.1
million in core capital)  or 20.95% of risk-weighted  assets of $145.4  million.
This amount was $18.8 million above the 8.0% requirement in effect on that date.
Security  Federal is a well capitalized  institution under the Prompt Corrective
Action Regulations.
 
IMPACT OF INFLATION AND CHANGING PRICES
 
    The Consolidated Financial Statements and  Notes thereto have been  prepared
in  accordance with  generally accepted  accounting principles,  which generally
requires the measurement of financial position and operating results in terms of
historical dollars (except for available-for-sale  securities which are at  fair
value) without considering the changes in the relative purchasing power of money
over  time  due  to inflation.  The  impact  of inflation  is  reflected  in the
increased cost  of  Financial  Security's  operations.  Unlike  most  industrial
companies,  nearly  all the  assets and  liabilities  of Financial  Security are
monetary in  nature.  As a  result,  interest rates  have  a greater  impact  on
Financial  Security's  performance  than do  the  effects of  general  levels of
inflation. Interest rates do  not necessarily move in  the same direction or  to
the same extent as the price of goods and services.

RATE VOLUME ANALYSIS
 
    The following schedule  presents the  dollar amount of  changes in  interest
income  and interest expense for major components of interest-earning assets and
interest-bearing liabilities. It  distinguishes between the  changes related  to
changes  in  interest  rates  and  changes  in  volume.  For  each  category  of
interest-earning and interest-bearing  liabilities, information  is provided  on
changes  attributable  to  (1)  changes  in  volume  (i.e.,  changes  in  volume
multiplied by the prior year's rate) and  (2) changes in rate (i.e., changes  in
rate  multiplied  by the  prior  year's balance).  For  purposes of  this table,
changes attributable to both  rate and volume, which  cannot be segmented,  have
been allocated proportionately to the change due to volume and the change due to
rate.

    of  unearned interest  netted against  the balance  of the  home improvement
    loans  at  December  31,  1995,  1994,  1993,  1992,  and  1991.  See  "Loan
    Participations  and Purchased Loans",  "Delinquencies and Classified Assets"
    and "Nonperforming Assets" under Item 1. Business in the Form 10-KSB for the
    fiscal year ended December 31, 1995 incorporated herein by reference.
 
(2) As certain of Security Federal loans have become delinquent 90 days or more,
    the interest that  would have been  earned has been  added to the  principal
    balance  of  the  loan  (capitalized) pursuant  to  Security  Federal's loan
    documents. Security Federal's reserve  for uncollected capitalized  interest
    was $273,000 at March 31, 1996. Security Federal's policy is to reserve 100%
    of capitalized interest for those loans delinquent 90 days or more.

leases  purchased from  Bennett Funding Group,  Inc., totaling  $1.6 million. On
March 28, 1996,  the U.S.  Attorney's office in  New York  City charged  Patrick
Bennett  and  Bennett  Funding Group,  a  Syracuse NY  company  ("Bennett") with
securities fraud and perjury in connection with Bennett's offering of up to  $80
million  in short-and-medium-term notes. In addition, the SEC filed suit against
Mr. Bennett  and his  related companies.  On April  1, 1996,  Bennett filed  for
Chapter  11  bankruptcy  protection  and ceased  payments  to  investors.  It is
uncertain what effect,  if any, the  Bennett litigation will  have on  Financial
Security.   Therefore   Financial  Security   has   classified  the   leases  as
non-performing and placed  them on  non-accrual status. The  lease payments  are
currently  being  received by  the bankruptcy  trustee.  It is  anticipated that
Financial Security will experience  a temporary loss of  interest on the  leases
until  they can  be transferred from  the trustee to  Security Federal. However,
there can be no assurance the additional losses will not be incurred due to  the
pending  litigation  against Bennett.  As of  March 31,  1996, $75,000  has been
reserved for potential losses. As of  March 31, 1996, $75,000 has been  reserved
for potential losses.

                     SUPERVISION AND REGULATION OF PINNACLE
 
    Pinnacle is extensively regulated under both federal and state law as a bank
holding   company  and  a  savings  and  loan  holding  company.  The  following
description briefly discusses certain provisions  of federal and state laws  and
certain  regulations and proposed  regulations and the  potential impact of such
provisions on Pinnacle and the Pinnacle Subsidiary Banks. To the extent that the
following information  describes  statutory  or  regulatory  provisions,  it  is
qualified  in  its  entirety  by  reference  to  the  particular  statutory  and
regulatory provisions.
 
GENERAL
 
    At the present time, various bills have been introduced in the United States
Congress and the  Illinois state  legislature which could  result in  additional
regulation  of the business of Pinnacle  and the Pinnacle Subsidiary Banks which
are now or hereafter become affiliated with Pinnacle. Future bills could also be
introduced which could significantly affect  the banking industry. It cannot  be
predicted  whether any  such legislation  will be  adopted or  how such adoption
would affect the business of Pinnacle or any of the Pinnacle Subsidiary Banks.
 
BANK HOLDING COMPANY
 
    As a bank  holding company, Pinnacle  is subject to  the supervision of  the
Federal  Reserve under the BHC Act. Bank  holding companies are required to file
with the Federal Reserve an annual report and such additional information as the
Federal  Reserve  may   require.  The  Federal   Reserve  also  makes   periodic
examinations  of bank holding  companies and their subsidiaries.  As a result of
Pinnacle's acquisition  of  Pinnacle  Savings, Pinnacle  is  also  considered  a
non-diversified savings and loan holding company subject to regulatory oversight
by  the OTS. As such,  Pinnacle is subject to  regulation and examination by the
OTS. Pinnacle is required  to obtain the prior  approval of the Federal  Reserve
before  it could acquire all or substantially all  of the assets of any bank, or
acquire ownership or  control of  any voting  shares of  any bank  other than  a
Pinnacle  Subsidiary Bank, if,  after such acquisition, it  would own or control
more than five percent (5%) of the voting shares of such bank. The BHC Act  does
not  permit the Federal  Reserve to approve  the acquisition by  Pinnacle of any
voting shares of, or all or substantially all of the assets of, any bank located
outside of  the  State of  Illinois,  unless such  acquisition  is  specifically
authorized by the laws of the state in which such bank is located.
 
    The  BHC  Act limits  the activities  which may  be engaged  in by  any bank
holding company and its subsidiaries to certain specified activities,  including
those  activities which the Federal Reserve may  find by order or regulation, to
be so closely related  to banking or  managing or controlling banks  as to be  a
proper incident thereto.
 
    There  are a number of obligations  and restrictions imposed on bank holding
companies and  their  depository institution  subsidiaries  by federal  law  and
regulatory  policy that  are designed to  reduce potential loss  exposure to the
depositors of such depository institutions and to the FDIC insurance fund in the
event the depository institution becomes in danger of default or in default. For
example, under a  policy of  the Federal Reserve  with respect  to bank  holding
company  operations, a bank holding company is  required to serve as a source of
financial strength  to  its subsidiary  depository  institutions and  to  commit
resources to support such institutions in circumstances where it might not do so
absent  such policy.  In addition,  the "cross-guarantee"  provisions of federal
law, require insured depository institutions  under common control to  reimburse
the  FDIC for any loss suffered or  reasonably anticipated by either the Savings
Association Insurance Fund  ("SAIF") or  the Bank  Insurance Fund  ("BIF") as  a
result of the default of a commonly controlled insured depository institution or
for  any  assistance  provided by  the  FDIC  to a  commonly  controlled insured
depository institution in danger of default. The FDIC may decline to enforce the
cross-guarantee provisions  if  it determines  that  a  waiver is  in  the  best
interest  of  the SAIF  or the  BIF or  both.  The FDIC's  claim for  damages is
superior to claims of stockholders of the insured depository institution or  its
holding  company but is  subordinate to claims  of depositors, secured creditors
and holders  of  subordinated  debt  (other than  affiliates)  of  the  commonly
controlled insured depository institutions.
 
                                      117
<PAGE>
    The  Federal Deposit Insurance Act also  provides that amounts received from
the liquidation or other resolution of any insured depository institution by any
receiver must  be distributed  (after  payment of  secured  claims) to  pay  the
deposit  liabilities of the institution prior to payment of any other general or
unsecured  senior  liability,  subordinated   liability,  general  creditor   or
stockholder.  This provision would give depositors a preference over general and
subordinated creditors and stockholders in the event a receiver is appointed  to
distribute the assets of any of the Pinnacle Subsidiary Banks.
 
    Subsidiary  banks of a bank holding company (such as the Pinnacle Subsidiary
Banks) are subject to certain restrictions imposed by the Federal Reserve Act on
any extensions of credit to the bank holding company or any of its subsidiaries,
on investments in the stock  or other securities thereof,  and on the taking  of
such stock or securities as collateral for loans to any borrower. Further, under
the  BHC Act and regulations of the  Federal Reserve, a bank holding company and
its subsidiaries are prohibited from engaging in certain tie-in arrangements  in
connection with any extension of credit, lease or sale of property or furnishing
of services.
 
BANKS
 
    The  operations of Pinnacle Bank and Quad-Cities Bank are subject to federal
and state  statutes and  regulations  applicable to  banks chartered  under  the
banking  laws  of the  State  of Illinois  and to  regulation  by the  FDIC. The
operations of Pinnacle Savings are  subject to federal statutes and  regulations
applicable  to thrifts chartered under the banking laws of the United States and
to regulation by the OTS. Pinnacle Savings is a member of the Federal Home  Loan
Bank of Chicago. The various laws and regulations administered by the regulatory
agencies  affect corporate  practices, such  as payment  of dividends, incurring
debt and acquisition of financial  institutions and other companies, and  affect
business  practices, such  as payment of  interest on deposits,  the charging of
interest on loans, types of business conducted and location of offices.
 
    Federal and state  banking laws  and regulations govern  or restrict,  among
other  things, the scope of a bank's  business, the investments a bank may make,
the reserves against deposits a bank must  maintain, the loans a bank makes  and
the  collateral it takes, the  activities of a bank  with respect to mergers and
consolidations, and  the  establishment  of branches.  Each  banking  regulatory
authority  has the authority to prevent a bank  from engaging in an unsafe or an
unsound practice in conducting its business. The payment of dividends, depending
upon the financial condition of a bank, could be deemed such a practice.
 
    As subsidiary banks of a bank holding company, the Pinnacle Subsidiary Banks
are subject to certain  restrictions imposed by the  Federal Reserve Act on  any
extensions  of credit to  Pinnacle or any  of the Pinnacle  Subsidiary Banks, on
investments in the stock or other securities of Pinnacle or any of the  Pinnacle
Subsidiary  Banks,  and on  taking such  stock or  securities as  collateral for
loans. Federal  statutes  and Federal  Reserve  regulations also  place  certain
limitations  and reporting  requirements on  extensions of  credit by  a bank to
principal stockholders of its parent holding company and to related interests of
such principal stockholders. In addition,  such legislation and regulations  may
affect  the terms upon  which any person  becoming a principal  stockholder of a
holding company may  obtain credit  from banks  with which  the subsidiary  bank
maintains a correspondent relationship.
 
    Furthermore, Federal statutes prohibit acquisition of "control" of a bank or
bank  holding company without  prior notice to  certain Federal bank regulators.
"Control" is  defined in  certain cases  as  acquisition of  as little  as  five
percent  (5%) of  the outstanding  shares. From time  to time,  various types of
federal and state legislation have been proposed that could result in additional
regulation of, and expansions or restrictions on, the business of the banks.  It
cannot  be predicted whether  any such legislation  will be adopted  or how such
legislation would affect the business of the banks.
 
INSURANCE OF DEPOSIT ACCOUNTS
 
    Deposits of the Pinnacle Subsidiary Banks are presently insured by the  SAIF
and  BIF. Both the SAIF and the BIF, the deposit insurance fund that covers most
commercial bank deposits, are
 
                                      118
<PAGE>
statutorily required to be recapitalized to a 1.25% of insured reserve  deposits
ratio.  Until recently, members of the SAIF  and BIF were paying average deposit
insurance premiums of between  23 and 31 basis  points. The BIF presently  meets
the  required  reserve ratio  and, therefor,  BIF  premiums are  currently zero,
whereas the SAIF is not expected to meet or exceed the required level until 2001
at the earliest. This  situation is primarily due  to the statutory  requirement
that  SAIF  members make  payments  on bonds  issued in  the  late 1980s  by the
Financing Corporation ("FICO") to recapitalize the predecessor to the SAIF.
 
    Legislation has been  proposed in  Congress to  mitigate the  effect of  the
BIF/SAIF  premium disparity. Under the legislation a special assessment would be
imposed on the amount  of deposits held  by SAIF-member institutions,  including
Pinnacle Savings and Security Federal, to recapitalize the SAIF fund. The amount
of  the special assessment  would be left to  the discretion of  the FDIC but is
generally estimated at between  75 to 85 basis  points of insured deposits.  The
legislation would also require that the BIF and the SAIF be merged by January 1,
1998,   provided  that  subsequent  legislation  is  enacted  requiring  savings
associations to become banks,  and that the FICO  payments be spread across  all
BIF  and SAIF  members. The  payment of  the special  assessment would  have the
effect of immediately reducing the  capital of SAIF-member institutions, net  of
any  tax  effect; however,  it would  not affect  Pinnacle Savings'  or Security
Federal's compliance with its regulatory capital requirements. Management cannot
predict whether legislation imposing such a fee will be enacted, or, if enacted,
the amount of any special assessment  or when and whether ongoing SAIF  premiums
will  be reduced to a  level equal to that of  BIF premiums. Management can also
not predict whether or when the BIF and SAIF will merge.
 
                     DESCRIPTION OF PINNACLE CAPITAL STOCK
 
    The capital stock of  Pinnacle consists of  20,000,000 authorized shares  of
Pinnacle Common Stock, $4.69 par value per share, and 1,000 authorized shares of
preferred  stock,  no  par value  per  share ("Pinnacle  Preferred  Stock"). The
following summary does not purport to be complete and is subject in all respects
to applicable Illinois law and Pinnacle's Articles of Incorporation and By-laws.
 
COMMON STOCK
 
    Pinnacle had 4,302,716 shares of Pinnacle Common Stock outstanding as of the
Pinnacle Record Date.  Each share of  Pinnacle Common Stock  is entitled to  one
vote  on all matters  submitted to a  vote of stockholders.  Holders of Pinnacle
Common Stock  are  entitled  to  receive  dividends  when  and  as  declared  by
Pinnacle's Board of Directors out of funds legally available therefor. Dividends
may  be  paid  on  the  Pinnacle  Common Stock  only  if  all  dividends  on any
outstanding Pinnacle Preferred Stock have been paid or provided for.
 
    The issued and outstanding shares of  Pinnacle Common Stock are, and  shares
to  be issued in the Merger will  be when issued, fully paid and non-assessable.
Holders of Pinnacle Common Stock have no preemptive or conversion rights and are
not subject to further calls or assessments by Pinnacle.
 
    In the event  of the  voluntary or involuntary  dissolution, liquidation  or
winding  up  of  Pinnacle, holders  of  Pinnacle  Common Stock  are  entitled to
receive, pro rata, after satisfaction in  full of the prior rights of  creditors
and  holders of Pinnacle Preferred Stock, if any, all of the remaining assets of
Pinnacle available for distribution.
 
    Directors are elected by a vote of the holders of Pinnacle Common Stock.
 
    Harris Trust and Savings Bank acts  as the transfer agent and registrar  for
the Pinnacle Common Stock.

PREFERRED STOCK
 
    Pinnacle  is authorized  to issue up  to 1,000 shares  of Pinnacle Preferred
Stock. At the present time, none  of the authorized Pinnacle Preferred Stock  is
issued and the Pinnacle Board of Directors has no present plan or commitment for
the  issuance of any Pinnacle Preferred Stock. Nevertheless, Pinnacle's Articles
of  Incorporation  permit  the  Pinnacle  Board  to  establish  the  rights  and
preferences  of the Pinnacle Preferred Stock,  in the exercise of their business
judgment, so as to facilitate the structuring of possible future financings  and
acquisitions   and  in  meeting  other  corporate  needs  which  may  arise.  If
opportunities arise which would make  desirable the issuance of preferred  stock
through  either  public offerings  or private  placements,  such stock  could be
authorized and issued  by the  Pinnacle Board without  receiving any  additional
approval  from the Pinnacle  stockholders, except as  may be required  by law or
regulatory authorities or pursuant to the  rules of any stock exchange on  which
Pinnacle's  securities may then be listed. In  the event of a hostile attempt to
take over Pinnacle, it might  be possible for the Pinnacle  Board to issue in  a
private  transaction a  series of  preferred stock  with rights  and preferences
which could impede the completion of  such a transaction. The specific terms  of
any  series of preferred  stock would depend primarily  on market conditions and
other factors existing at that time of issuance.
 
    The power  of the  Pinnacle Board  to issue  Pinnacle Preferred  Stock  with
voting  or other rights which might impede  or deter a takeover attempt may make
Pinnacle a less attractive  takeover candidate and  may deter takeover  attempts
not approved by the Pinnacle Board, in which Pinnacle stockholders might receive
for some or all of their shares a substantial premium above market value at that
time  the takeover bid is made. Additionally, issuance of the Pinnacle Preferred
Stock could result in a class  of securities outstanding that will have  certain
preferences  with respect to  dividends and in  liquidation over Pinnacle Common
Stock. Such preferred shares  could enjoy certain  voting rights, contingent  or
otherwise,  in addition to those of Pinnacle Common Stock, which could result in
the dilution of the voting rights, net  income per share, and net book value  of
Pinnacle Common Stock.
 
                               DISSENTER'S RIGHTS
 
    Dissenting  stockholders  of Financial  Security  who follow  the procedures
specified in Section 262 of  the DGCL ("Section 262")  will be entitled to  have
their  shares of Financial Security Common Stock appraised by the Delaware Court
of Chancery and to receive payment of the "fair value" of such shares, exclusive
of any element of  value arising from the  accomplishment or expectation of  the
Merger, as determined by such Court. A dissenting stockholder should assume that
neither  Financial Security nor Pinnacle will take  any action to perfect his or
her appraisal rights.  Therefor, a  stockholder desiring  to exercise  appraisal
rights  should strictly comply with the procedures  set forth in Section 262 and
is urged to consult his  or her legal advisor  before electing or attempting  to
exercise  such rights. Failure to follow any  of such procedures may result in a
termination or waiver of appraisal rights under Section 262.
 
    The following discussion of the provisions of Section 262 is not intended to
be a complete statement of  its provisions and is  qualified in its entirety  by
reference  to the full text of that section,  a copy of which is included herein
as Appendix III.
 
    Under Section 262, a dissenting  stockholder electing to exercise  appraisal
rights must satisfy both of the requirements set forth in paragraphs (1) and (2)
below:
 
        (1)  Deliver to Financial Security, before the taking of the vote on the
    proposal to adopt  and approve the  Merger Agreement, a  written demand  for
    appraisal  of his  or her  shares of  Financial Security  Common Stock which
    reasonably informs Financial Security of the identity of the stockholder  of
    record  and that such stockholder intends thereby to demand the appraisal of
    his or her shares of Financial Security Common Stock. This written demand is
    in addition to and
 
                                      121
<PAGE>
    separate from any proxy  or vote against the  proposal to approve and  adopt
    the  Merger. Neither a vote against such proposal nor a proxy directing such
    vote shall  satisfy the  requirement for  such written  demand. The  written
    demand  for appraisal should be delivered  either in person to the Secretary
    of Financial  Security  at  the  Financial  Security  Meeting,  or  by  mail
    (certified  mail, return  receipt requested,  being the  recommended form of
    transmittal) to: Secretary, Financial  Security Corp., 1209 North  Milwaukee
    Avenue,  Chicago, Illinois 60622 before the  vote on the proposal to approve
    the Merger; and
 
        (2) Not vote in favor of the Merger Agreement. A failure to vote against
    such proposal will not constitute a waiver of appraisal rights. However, any
    stockholder who  executes a  proxy and  who desires  to perfect  his or  her
    appraisal  rights must mark the proxy  "Against" the proposal to approve the
    Merger Agreement or must abstain because if the proxy is left blank, it will
    be voted for such proposal.
 
    The written demand for appraisal must be made by or for the holder of record
of the shares of  Financial Security Common Stock  as of the Financial  Security
Record  Date and  such shares  must be  held continuously  through the Effective
Time. Accordingly, such demand should be executed by or for such stockholder  of
record,  fully and correctly, as  such stockholder's name appears  on his or her
stock certificates. If the shares of  Financial Security Common Stock are  owned
of  record in a fiduciary capacity, such as by a trustee, guardian or custodian,
execution of the  demand should be  made in such  capacity and if  the stock  is
owned  of record  by more  than one  person, in  a joint  tenancy or  tenancy in
common, such demand should be executed by or for all joint owners. An authorized
agent, including one of  two or more  joint owners, may  execute the demand  for
appraisal  for a  stockholder of  record. However,  the agent  must identify the
record owner or  owners and expressly  disclose the fact  that in executing  the
demand he or she is acting as agent for such record owner or owners.
 
    If  any Financial  Security stockholder  fails to  comply with  any of these
conditions and the Merger becomes effective, he will be entitled to receive  the
Merger  Consideration provided  for in  the Merger  Agreement, but  will have no
appraisal rights with respect to his or her shares of Financial Security  Common
Stock.
 
    DISSENTING  STOCKHOLDERS WHO  ARE NOT THE  OWNERS OF RECORD  OF THEIR SHARES
SHOULD CONSULT THEIR LEGAL COUNSEL REGARDING THE RIGHT OF APPRAISAL WITH RESPECT
TO THEIR SHARES OF FINANCIAL SECURITY COMMON STOCK.
 
    Within ten days after the Effective  Time, Pinnacle will notify each  former
stockholder  of Financial Security who has satisfied the foregoing conditions of
the date  on  which the  Merger  became effective.  Within  120 days  after  the
Effective Time, Pinnacle or any such stockholder who has satisfied the foregoing
conditions  and is otherwise entitled to  appraisal rights under Section 262 may
file a petition in the Delaware  Court of Chancery demanding a determination  of
the fair value of the shares of Financial Security Common Stock formerly held by
all  stockholders entitled  to appraisal rights.  If no such  petition is filed,
appraisal rights will be lost for  all stockholders who had previously  demanded
appraisal  of  their  shares  of  Financial  Security  Common  Stock. Dissenting
stockholders seeking to  exercise appraisal rights  should assume that  Pinnacle
will  not  file a  petition with  respect to  the appraised  value of  shares of
Financial Security  Common  Stock  and  that  Pinnacle  will  not  initiate  any
negotiations  with respect to  the "fair value" of  shares of Financial Security
Common Stock. Accordingly, stockholders of  Financial Security Common Stock  who
wish  to exercise their appraisal rights should regard it as their obligation to
take all  steps  necessary to  perfect  their  appraisal rights  in  the  manner
prescribed in Section 262.
 
    Within 120 days after the Effective Time, any dissenting stockholder who has
complied  with the provisions of Section  262 is entitled, upon written request,
to receive  from Pinnacle  a statement  setting forth  the aggregate  number  of
shares  of Financial  Security Common  Stock not  voted in  favor of  the Merger
Agreement and, with  respect to  which demands  for appraisal  were received  by
Pinnacle,
 
                                      122
<PAGE>
the  number of holders of  such shares of Financial  Security Common Stock. Such
statement must be  mailed by Pinnacle  within ten days  after expiration of  the
time  for  delivery of  demands for  appraisal under  Section 262,  whichever is
later.
 
    If a petition  for an appraisal  is timely  filed, after a  hearing on  such
petition,  the Delaware Court of Chancery will determine the former stockholders
of Financial Security entitled to appraisal  rights and will appraise the  value
of  the  shares  of  Financial  Security Common  Stock  formerly  owned  by such
stockholders, determining the  "fair value"  exclusive of any  element of  value
arising from the accomplishment or expectation of the Merger.
 
    Although  Pinnacle  and Financial  Security believe  that  the terms  of the
Merger are fair, neither can  make any representation as  to the outcome of  any
appraisal  of "fair value" as determined by  the Delaware Court of Chancery, and
stockholders  should  recognize  that  such  an  appraisal  could  result  in  a
determination  of a lower, higher or equivalent value. Moreover, Pinnacle may or
may not argue in an appraisal proceeding for a determination of "fair value"  by
the   Delaware  Court  of  Chancery  which  is  lower  than  the  value  of  the
consideration received by  stockholders of  Financial Security  pursuant to  the
Merger  Agreement. In  determining the "fair  value" of the  shares of Financial
Security Common Stock, asset values, dividends, earnings, prospects, the  nature
of the enterprise and other facts which could be ascertained as of the Effective
Time  of the Merger may be taken into account by the Delaware Court of Chancery.
The Delaware Supreme Court  has stated with respect  to Section 262 that,  among
other  things, "proof of value by any  techniques or methods which are generally
considered acceptable in  the financial  community and  otherwise admissible  in
court"  should be considered  in an appraisal  proceeding. In addition, Delaware
courts have  decided  that the  statutory  appraisal remedy,  depending  on  the
relevant  facts and circumstances,  may or may not  be a stockholder's exclusive
remedy in connection with mergers similar to the Merger.
 
    The Court of Chancery may also, on application, (i) determine a fair rate of
interest, simple or compound, if any,  to be paid to dissenting stockholders  in
addition to the value of the Financial Security Common Stock for the period from
the Effective Time of the Merger to the date of payment, (ii) assess costs among
the parties as the court deems equitable and (iii) order all or a portion of the
expenses incurred by any dissenting stockholder in connection with the appraisal
proceeding  including, without  limitation, reasonable attorney's  fees and fees
and expenses of experts to be charged  pro rata against the value of all  shares
entitled  to appraisal.  Determinations by  the Court  are subject  to appellate
review by the Delaware Supreme Court.
 
    Any dissenting stockholder of  Financial Security who  has duly demanded  an
appraisal  in compliance with Section 262 will  not, after the Effective Time of
the Merger, be entitled to vote the capital stock of Financial Security for  any
purpose  nor be entitled to  the payment of dividends  or other distributions on
his or her shares of Financial Security Common Stock.
 
    If no petition for an appraisal is  filed within the time provided, or if  a
former  stockholder  of  Financial  Security  delivers  to  Pinnacle  a  written
withdrawal of  his or  her demand  for an  appraisal and  an acceptance  of  the
consideration  payable pursuant to  the Merger Agreement,  either within 60 days
after the Effective  Time or  with the written  approval of  Pinnacle, then  the
right  of such stockholder to an appraisal will cease and such stockholder shall
be entitled  to  receive  the  consideration  payable  pursuant  to  the  Merger
Agreement,  without interest, as if he or  she had not demanded appraisal of his
or  her  shares  of  Financial  Security  Common  Stock.  No  pending  appraisal
proceeding  in the  Court of  Chancery will be  dismissed as  to any stockholder
without the approval  of the court,  which approval may  be conditioned on  such
terms as the court deems just.
 
    FAILURE  TO COMPLY STRICTLY WITH THESE PROCEDURES WILL CAUSE THE STOCKHOLDER
TO LOSE HIS DISSENTER'S RIGHTS.

                       COMPARATIVE RIGHTS OF STOCKHOLDERS
 
    Upon consummation of the Merger, holders of Financial Security Common  Stock
may  receive  shares of  Pinnacle  Common Stock  and  become stockholders  of an
Illinois corporation and have no further  rights as a stockholder of a  Delaware
corporation.  As Financial Security  will not survive  the Merger, the Financial
Security Certificate of Incorporation will cease to apply to Financial  Security
stockholders  who thereafter,  while they hold  Pinnacle Common  Stock, shall be
subject to the Pinnacle Articles of Incorporation. The following is a summary of
certain material differences  between the IBCA  and the DGCL  and the  governing
documents  of Pinnacle and Financial Security  which may affect the interests of
holders of Financial Security Common Stock, but  is not meant to be relied  upon
as  an exhaustive list or a detailed description of the provisions discussed and
is  qualified  in  its  entirety  by  reference  to  the  Pinnacle  Articles  of
Incorporation  and By-Laws and Financial Security's Certificate of Incorporation
and By-Laws, as well as the IBCA and the DGCL.
 
SPECIAL MEETINGS OF STOCKHOLDERS
 
    Under the  IBCA, a  special meeting  of stockholders  may be  called by  the
president,  the board of directors, by the holders of not less than one-fifth of
all the outstanding shares entitled to vote on the matter for which the  meeting
is  called  or by  any person  authorized  by the  articles of  incorporation or
by-laws to  call a  special  meeting. Pinnacle's  By-laws provide  that  special
meetings  of the stockholders for  any purpose or purposes  may be called at any
time by the Chairman  of the Pinnacle  Board of Directors,  by the President  or
Secretary, or by a request of any four of the directors.
 
    The DGCL permits a special meeting of stockholders to be called by the board
of  directors  or  by  such  person  or persons  as  may  be  authorized  by the
certificate of incorporation or by-laws. The Financial Security By-laws  provide
that special meetings of the stockholders of Financial Security may be called by
the  Financial Security Board pursuant to a  resolution adopted by a majority of
the total number of the Directors  which Financial Security would have if  there
were no vacancies on the Financial Security Board.
 
STOCKHOLDER ACTION BY WRITTEN CONSENT
 
    Unless  otherwise provided in the articles of incorporation, the IBCA allows
action to be taken by  an Illinois corporation without  a meeting and without  a
vote  if a  consent in  writing setting forth  the action  to be  taken shall be
signed by: (i) all the stockholders entitled to vote with respect to the subject
matter thereof or (ii) the holders of outstanding shares having not less than  a
minimum number of votes that would be necessary to authorize or take such action
at  a meeting  at which  all shares  entitled to  vote thereon  were present and
voting, provided certain notice is given to all stockholders of the corporation.
The Pinnacle Articles of Incorporation do not restrict stockholders from  taking
action by written consent.
 
    The  DGCL provides that  action may be  taken without a  meeting and without
prior notice if a consent setting forth  the action so taken shall be signed  by
the  holders of  outstanding stock  having not less  than the  minimum number of
votes that would be necessary to authorize  or take such action at a meeting  at
which  all shares entitled to vote thereon  were present and voted, provided the
certificate of  incorporation does  not  state otherwise.  Financial  Security's
Certificate  of  Incorporation does  not  permit stockholder  action  by written
consent.
 
REQUIRED STOCKHOLDER VOTE FOR CERTAIN ACTIONS
 
    The IBCA generally requires  the approval of a  majority of a  corporation's
Board  of Directors  and the holders  of more  than two-thirds of  all the votes
entitled to be cast thereon by each voting group entitled to vote on any plan of
merger or consolidation, plan of share exchange or sale of substantially all  of
the  assets of a  corporation not in  the ordinary course  of business. The IBCA
also  specifies  additional  voting  requirements  for  affiliated  mergers  and
transactions  that would  cause an  acquiring person's  voting power  to meet or
exceed specified  thresholds. The  Pinnacle  Articles of  Incorporation  neither
impose  a super majority  voting requirement for  certain transactions nor limit
the voting power of  large stockholders, in contrast  to the Financial  Security
Certificate of Incorporation.
 
                                      124
<PAGE>
    The  DGCL provides that in most matters other than the election of directors
and the approval of a  plan of merger, the affirmative  vote of the majority  of
shares  present in person or represented by proxy at the meeting and entitled to
vote on the subject matter shall be the act of the stockholders. Directors shall
be elected  by a  plurality of  the votes  of the  shares present  in person  or
represented  by  proxy  at the  meeting  entitled  to vote  on  the  election of
directors. The certificate of incorporation of any corporation may provide  that
at  all elections of  directors of the  corporation, or at  elections held under
specified circumstances,  each holder  of stock  or any  class or  classes of  a
series  or series thereof shall be entitled to  as many votes as shall equal the
number of votes  which (except for  such provision as  to cumulative voting)  he
would  be entitled to  cast with the  election of directors  with respect to his
shares of stock multiplied by the number of directors to be elected by him,  and
he may cast all of such votes for a single director or may distribute them among
the  number to be voted for, or  any two or more of them  as he may see fit. The
Financial  Security  Certificate  of  Incorporation  does  not  grant  Financial
Security stockholders cumulative voting rights.
 
    The  Financial Security Certificate of  Incorporation provides that an owner
of shares of Financial Security Common Stock who beneficially owns, directly  or
indirectly,  in excess of  ten percent (10%)  of the then  outstanding shares of
Financial Security Common Stock (the "Limit") shall not be entitled or permitted
to any vote in  respect of the  shares held in excess  of the Limit.  Beneficial
ownership  includes (i) shares beneficially  owned by such person  or any of his
affiliates (as defined in the Financial Security Certificate of  Incorporation),
(ii)  shares which such person or his  affiliates have the right to acquire upon
the exercise of conversion rights or options  and (iii) shares as to which  such
person  and his affiliates have  or share investment or  voting power, but shall
not include shares  beneficially owned by  an employee stock  ownership plan  or
directors,  officers and employees of Security  Federal or Financial Security or
shares that  are  subject  to a  revocable  proxy  and that  are  not  otherwise
beneficially,  or deemed by Financial Security to be beneficially, owned by such
person and his affiliates. The  Financial Security Certificate of  Incorporation
further  provides that this provision limiting voting rights may only be amended
upon the  vote of  eighty percent  (80%) of  the stockholders  entitled to  vote
thereon.
 
    Under  the Financial Security Certificate  of Incorporation, the affirmative
vote of the holders of at least eighty percent (80%) of the voting power of  the
then outstanding shares of stock entitled to vote is required in connection with
any  transaction involving an  Interested Stockholder (as  defined below) except
(i) in cases where the  proposed transaction has been  approved in advance by  a
majority  of those members of the Financial  Security Board of Directors who are
unaffiliated with the  Interested Stockholder  and were directors  prior to  the
time  when the Interested Stockholder became  an Interested Stockholder; or (ii)
if the proposed transaction met certain  conditions set forth therein which  are
designed  to afford  the stockholders  a fair  price in  consideration for their
shares in cases where a vote of  a majority of the outstanding shares of  voting
stock  is required for approval. The term "Interested Stockholder" is defined to
include any individual,  corporation, partnership  or other  entity (other  than
Financial  Security or  its subsidiaries)  which owns  beneficially or controls,
directly or indirectly, ten percent (10%)  or more of the outstanding shares  of
voting  stock of  Financial Security. This  provision of  the Financial Security
Certificate of  Incorporation applies  to any  "Business Combination"  which  is
defined  to include (i) any merger or consolidation of Financial Security or any
of its subsidiaries  with or  into any  Interested Stockholder;  (ii) any  sale,
lease,  exchange,  mortgage,  transfer,  or other  disposition  to  or  with any
Interested Stockholder or affiliate of an Interested Stockholder of  twenty-five
percent  (25%) or more  of the consolidated assets  of Financial Security; (iii)
the issuance  or transfer  to  any Interested  Stockholder  or affiliate  of  an
Interested  Stockholder  by  Financial  Security  (or  any  subsidiary)  of  any
securities of Financial Security in exchange for any assets, cash, securities or
other property (or  combination thereof) the  value of which  equals or  exceeds
twenty-five  percent (25%)  of the  combined "Fair  Market Value"  as defined in
Financial Security's Certificate of  Incorporation of the outstanding  Financial
Security  Common Stock;  (iv) the  adoption of any  plan for  the liquidation or
dissolution of Financial  Security proposed by  or on behalf  of any  Interested
Stockholder or affiliate
 
                                      125
<PAGE>
thereof; and (v) any reclassification of securities, recapitalization, merger or
consolidation  of  Financial Security  which has  the  effect of  increasing the
proportionate share of Financial Security Common Stock or any class of equity or
convertible securities of Financial Security owned directly or indirectly, by an
Interested Stockholder or affiliate thereof.
 
AMENDMENT OF ARTICLES OR BY-LAWS
 
    The IBCA provides that a corporation may amend its articles of incorporation
at any time and from time to time to add a new provision or to change or  remove
an  existing provision, provided that the  articles as amended contain only such
provisions as are required or permitted in original articles of incorporation at
that time of the amendment. A majority of the whole board of directors may adopt
one or  more amendments  to its  articles of  incorporation without  stockholder
action  in any of the following instances: (i) to remove the names and addresses
of the initial directors if such  directors were named in the original  articles
of  incorporation; (ii) to remove the name and address of the initial registered
agent or the address of the initial registered office, if a statement of  change
is  on file with the Secretary of  State; (iii) to increase, decrease, create or
eliminate the par  value of  the shares of  any class,  so long as  no class  or
series  of shares  is adversely effected;  (iv) to  split all of  the issued and
authorized, but unissued, shares of any class, whether or not any shares of  the
class  are issued or outstanding, by multiplying them by a whole number, so long
as no  class or  series  of shares  is adversely  effected;  (v) to  change  the
corporate   name  by   substituting  the   word  "corporation",  "incorporated",
"company", "limited", or the abbreviation "Corp.", "Inc.", "Co.", or "Ltd.", for
a similar  word  or  abbreviation  in  the name  or  by  adding  a  geographical
attribution  to the  name; (vi)  to reduce  the authorized  shares of  any class
pursuant to a  cancellation statement filed  with respect to  such shares  after
acquisition  by  the  corporation  in circumstances  in  which  the  articles of
incorporation prohibit  reissuance  of  such shares  after  acquisition  by  the
corporation;  or (vii)  to restate  its articles  of incorporation  as currently
amended, such  restated articles  to  supersede the  original articles  and  all
amendments thereto. Any amendment which may be adopted by the action of both the
directors  and the stockholders shall be  adopted upon receiving the affirmative
vote of at least two-thirds of the votes of the shares entitled to vote on  such
amendment,  unless any class or series of shares  is entitled to vote as a class
in respect thereof, in which event the proposed amendment shall be adopted  upon
receiving  the affirmative  votes of  at least  two-thirds of  the votes  of the
shares of each class or series of shares entitled to vote as a class in  respect
thereof and of the total votes of the shares entitled to vote on such amendment.
 
    The  articles of incorporation may supersede the two-thirds vote requirement
by specifying any smaller or larger vote requirement not less than a majority of
the votes  of shares  entitled to  vote on  the amendment  and not  less than  a
majority  of the votes of the shares of  each class or series of shares entitled
to vote as a class on the  amendment. The Pinnacle Articles of Incorporation  do
not supersede the two-thirds vote requirement. Pinnacle's By-laws may be amended
by a majority of either the stockholders or the directors.
 
    The  DGCL provides that after a corporation  has received payment for any of
its capital stock, it may amend  its certificate of incorporation, from time  to
time,  in as  many respects  as may be  desired, so  long as  its certificate of
incorporation as  amended would  contain only  such provisions  as it  would  be
lawful and proper to insert in an original certificate of incorporation filed at
that  time of  the filing of  the amendment;  and, if a  change in  stock or the
rights of stockholders,  or any  exchange, reclassification  or cancellation  of
stock  or  rights of  stockholders  is to  be made,  such  provisions as  may be
necessary to effect such change, exchange, reclassification or cancellation.  If
the  corporation has capital stock,  then an amendment to  the articles shall be
adopted if a majority of  the outstanding stock entitled  to vote thereon and  a
majority  of the outstanding stock  of each class entitled  to vote thereon as a
class has  been voted  in favor  of the  amendment. If  the corporation  has  no
capital  stock, then the amendment shall be adopted  if a majority of all of the
members of the governing body shall vote in favor of such amendment.
 
                                      126
<PAGE>
    The Financial Security  Certificate of Incorporation  requires that  certain
amendments thereto receive the affirmative vote of at least eighty percent (80%)
of  the voting power  of all the  then outstanding shares  of Financial Security
Common Stock, voting as a single class.
 
    The Financial Security By-laws may be amended or repealed by the affirmative
vote of a  majority of  the Financial  Security Board  of Directors;  or by  the
affirmative vote of at least eighty percent (80%) of the voting power of all the
then  outstanding shares of voting  stock, voting together as  a single class at
any legal meeting.
 
INSPECTION OF STOCKHOLDER LISTS
 
    Under the IBCA,  in order to  inspect and  copy the corporate  records of  a
corporation,  including the  stockholder list,  a stockholder  must make written
demand upon the corporation, stating with particularity the records sought to be
examined and the purpose  therefor. A stockholder's purpose  must be proper.  In
addition,  under the  IBCA, all stockholders  may, during  usual business hours,
inspect and copy, at his or her expense, the stockholder list during the  period
beginning ten days prior to a meeting and continuing to the date of the meeting,
and any stockholder may inspect the list at any time during the meeting.
 
    Under  the DGCL,  a stockholder shall  have the right  during usual business
hours to inspect for any proper purpose the corporation's records, upon  written
demand  stating the purpose thereof. A proper purpose means a purpose reasonably
related to  such person's  interest  as a  stockholder.  In addition,  the  DGCL
permits  any stockholder of record to inspect the stockholder list for a purpose
germane to the meeting during ordinary business hours for the period  commencing
at  least ten  days before  a stockholders'  meeting and  continuing through the
meeting.
 
APPRAISAL RIGHTS IN MERGERS
 
    Under the IBCA, a stockholder  is entitled, under certain circumstances,  to
receive  payment of the fair value of the stockholder's stock if the stockholder
dissents from a  proposed merger  or consolidation and  either: (i)  stockholder
authorization  is  required  for  the  merger  or  consolidation;  or  (ii)  the
corporation is a subsidiary that is merged with its parent or another subsidiary
under Section 11.30 of  the IBCA. In addition  to being applicable generally  in
the  case of a merger,  under the IBCA, dissenters'  rights are available in the
case of: (i) a sale or exchange of all or substantially all of the assets of the
corporation; (ii) an amendment of the articles of incorporation that  materially
and  adversely effects rights in respect of  a dissenter's shares; and (iii) any
other corporate action which  grants a stockholder such  rights pursuant to  its
articles  of  incorporation,  by-laws  or  resolutions.  Pinnacle's  Articles of
Incorporation and Pinnacle's By-laws do not contain provisions granting Pinnacle
stockholders dissenter's rights.
 
    Pursuant to Section 262 of the DGCL, a holder of capital stock of a Delaware
corporation is generally entitled to receive  payment of the appraised value  of
his  or her shares if  such stockholder dissents from  a merger or consolidation
and complies  with the  procedures set  forth in  Section 262  of the  DGCL  for
exercising such rights. However, appraisal rights are not available in merger or
consolidation  transactions to holders of (i) shares either listed on a national
stock exchange  or  designated  as  a national  market  system  security  on  an
interdealer  quotation system by the National Association of Securities Dealers,
Inc. or  held of  record by  more  than 2,000  persons, or  (ii) shares  of  the
corporation surviving a merger unless, in either case, holders of such stock are
required  by the terms of  the merger or consolidation  to accept anything other
than (a) shares of the surviving  or resulting corporation; (b) shares of  stock
of  another corporation  so listed  or held  of record  by not  fewer than 2,000
persons; and/or (c)  cash in  lieu of  fractional shares  of such  corporations.
Appraisal  rights are not available for a sale  of assets or an amendment to the
certificate unless made applicable by affirmative provision in the corporation's
certificate of incorporation. See "DISSENTERS' RIGHTS".
 
DIRECTORS AND CLASSES OF DIRECTORS; VACANCIES AND REMOVAL OF DIRECTORS
 
    The Pinnacle By-laws provide that the number of directors shall be twenty or
such fewer number as is  determined by the Pinnacle Board  in the notice of  the
meeting whereat directors are to be elected.
 
                                      127
<PAGE>
    In  addition, the Pinnacle By-laws provide that any vacancy occurring on the
Pinnacle Board, including a vacancy resulting from an increase in the number  of
directors,  may be filled by the affirmative vote of a majority of the remaining
directors, though less than a quorum of the Pinnacle Board. Directors so  chosen
shall  hold office for a  term expiring at the  next following annual meeting of
stockholders at  which directors  are  elected. No  decrease  in the  number  of
directors  constituting  the  Pinnacle  Board  shall  shorten  the  term  of any
incumbent director.
 
    The Pinnacle By-laws further provide that any director may be removed,  with
or  without cause, only by the affirmative vote of the holders of all the shares
of stock  outstanding and  entitled to  vote at  a meeting  of the  stockholders
called for that purpose.
 
    The  Financial Security Certificate of Incorporation and By-laws require the
Financial Security Board  to be divided  into three classes  as nearly equal  in
number  as possible and that the members of  each class be elected for a term of
three years and until their successors are elected and qualified, with one class
being elected annually. The Financial  Security By-laws provide that the  number
of  directors shall be designated by the Financial Security Board, except in the
absence of such designation the number shall be six.
 
    The Financial Security  By-laws provide  that any vacancy  occurring in  the
Financial   Security   Board,   whether  by   death,   resignation,  retirement,
disqualification, removal or other cause, may be filled only by the  affirmative
vote  of a  majority of the  remaining directors,  though less than  a quorum. A
director elected to fill a vacancy shall serve for the unexpired portion of  the
term  or until his successor is elected and qualified. No decrease in the number
of directors constituting the Board of  Directors shall shorten the term of  any
incumbent director.
 
    Under  the Financial Security Certificate of Incorporation, any director may
be removed for  cause by the  holders of at  least eighty percent  (80%) of  the
outstanding shares, voting together as a single class.
 
NOTICE OF DIRECTOR NOMINATIONS
 
    Neither  Pinnacle's  Articles  of  Incorporation  nor  By-laws  address  the
procedure pursuant  to which  a stockholder  may nominate  a candidate  for  the
Pinnacle  Board  or  bring new  business  before  the meeting.  Pursuant  to the
Exchange Act, a Pinnacle stockholder wishing to present a proposal at the annual
meeting of  stockholders  must  present the  proposal  at  Pinnacle's  principal
executive  offices not less than  120 calendar days in  advance of the date that
Pinnacle's proxy statement is released to its security holders for the  previous
year's  annual meeting  of stockholders. In  addition, at the  annual meeting of
stockholders, a Pinnacle stockholder would be  permitted to present a motion  to
nominate a candidate for the Pinnacle Board.
 
    Under Financial Security's By-laws, stockholders may nominate candidates for
the Financial Security Board by delivering or mailing to the principal executive
offices  of Financial Security, a nomination not  less than ninety days prior to
the date of the meeting at which  the election will take place; provided in  the
event that stockholders receive less than 100 days notice or prior disclosure of
the  date of the meeting at which  the election for the Financial Security Board
shall take  place,  such nomination  by  the  stockholder must  be  received  by
Financial  Security  not later  than  the close  of  business on  the  tenth day
following the day on which such notice of  the day of the meeting was mailed  or
public  disclosure of said meeting was made. The stockholder nomination must set
forth certain information about the nominee and any information that is required
to be disclosed in solicitations of proxies with respect to director nominees as
required pursuant to  Regulation 14A under  the Exchange Act.  Such notice  must
also  set  forth certain  information about  the  person submitting  the notice,
including the name and address  of the stockholder and  the class and number  of
shares  of Financial Security  Common Stock that are  beneficially owned by such
stockholder. The officer of Financial Security presiding at the meeting at which
the election will take place shall disregard nominations not made in  accordance
with  the foregoing provisions. Under Financial Security's By-Laws, stockholders
 
                                      128
<PAGE>
must also provide advance  notice for certain business  to be brought before  an
annual meeting. The notice procedure and the information required to be provided
is substantially the same as described above.
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
    The IBCA generally provides that a corporation may make distributions to its
stockholders   unless,  after  giving  effect   to  the  distribution,  (i)  the
corporation would be insolvent; or (ii) the net assets of the corporation  would
be  less  than zero  or less  than the  maximum  amount payable  at the  time of
distribution to stockholders  having preferential rights  in liquidation if  the
corporation were then to be liquidated. In addition to the limitations set forth
in  the IBCA, there are various  regulatory requirements which are applicable to
distributions by holding companies  such as Pinnacle. For  a description of  the
regulatory  limitations  on  distributions  by  Pinnacle,  see  "SUPERVISION AND
REGULATION OF PINNACLE".
 
    The DGCL  provides that  the  directors of  a  corporation, subject  to  any
restrictions  contained in its certificate of incorporation, may declare and pay
dividends upon  the shares  of  its capital  stock, or  to  its members  if  the
corporation  is a non-stock corporation organized  for profit, either (i) out of
its surplus, or  (ii) in case  there shall be  no such surplus,  out of its  net
profits  for  the fiscal  year  in which  the  dividend is  declared  and/or the
preceding year. If the capital of the corporation shall have been diminished  by
depreciation  in the value  of its property,  or by losses,  or otherwise, to an
amount less than the aggregate amount  of the capital represented by the  issued
and  outstanding stock in all classes  having a preference upon the distribution
of assets, the directors of  such corporation shall not  declare and pay out  of
such  net profits any  dividends upon any  shares of any  classes of its capital
stock until the deficiency  in the amount of  capital represented by the  issued
and  outstanding stock of all classes  having a preference upon the distribution
of assets shall have been repaired.
 
DIRECTOR AND OFFICER DISCRETION
 
    The IBCA provides that  the board of directors,  committees of the board  of
directors, individual directors and individual officers of a corporation may, in
considering  the corporation's best long term  and short term interests consider
the effects  of  any action  upon  employees,  suppliers and  customers  of  the
corporation   or  its  subsidiaries,  communities  in  which  offices  or  other
establishments of the corporation or its subsidiaries are located and all  other
pertinent  factors.  The  Pinnacle  Articles  of  Incorporation  do  not address
director and officer discretion.
 
    The DGCL does not  contain a comparable provision  and, under Delaware  law,
the consideration that a board may give to nonstockholder constituencies is less
clear. Financial Security's Certificate of Incorporation provides that Financial
Security's  Board, when  evaluating any  offer of another  person to  (i) make a
tender or exchange  offer for any  equity security of  Financial Security,  (ii)
merge  or consolidate Financial  Security with another  corporation or entity or
(iii) purchase or otherwise acquire all  or substantially all of the  properties
and  assets of Financial Security,  may, in connection with  the exercise of its
judgment in determining what is the best interest of Financial Security and  its
stockholders, give due consideration to all relevant factors, including, without
limitation,  the  social and  economic  effect of  acceptance  of such  offer on
Financial Security's present and future customers and employees and those of its
subsidiaries;  on  the   communities  in  which   Financial  Security  and   its
subsidiaries  operate or  are located; on  the ability of  Financial Security to
fulfill its corporate objectives  as a savings and  loan holding company and  on
the   ability   of   Security   Federal  to   fulfill   the   objectives   of  a
federally-chartered stock  form savings  and loan  association under  applicable
statutes  and regulations. By  having these standards  in the Financial Security
Certificate of Incorporation, the Financial Security Board may be in a  stronger
position  to oppose such a transaction if the Financial Security Board concludes
that the transaction would not be in the best interest of Security Federal, even
if the price offered is significantly greater than the then market price of  any
equity security of Financial Security.

INDEMNIFICATION
 
    The  Pinnacle By-laws  provide that to  the fullest extent  permitted by the
IBCA and  any other  applicable  law, Pinnacle  shall  indemnify a  director  or
officer  of Pinnacle who  is or was a  party to any proceeding  by reason of the
fact that he is or was  such a director or officer or  is or was serving at  the
request  of the corporation as a director, officer, employee or agent of another
corporation,  partnership,  joint  venture,  trust,  or  other  enterprise.  The
Pinnacle  Board  is empowered,  by majority  vote of  a quorum  of disinterested
directors, or  by independent  legal counsel  in  a written  opinion or  by  the
stockholders  to  determine in  a  specific case  to  indemnify any  director or
officer.
 
    In addition, the Pinnacle Articles of Incorporation provide that a  director
shall  not be  personally liable  to Pinnacle  or its  stockholders for monetary
damages for a breach  of fiduciary duty, provided  that a director shall  remain
liable  for monetary damages  for any of  the following: (i)  an act or omission
that is grossly negligent; (ii) a breach of the duty of loyalty to Pinnacle  and
its  stockholders; (iii)  acts or  omissions not in  good faith  or that involve
intentional misconduct or a  knowing violation of law;  (iv) a transaction  from
which  the director  derived an  improper personal benefit;  and (v)  any act or
omission occurring before May 11, 1995, the effective date of the provision.
 
    The DGCL provides that a corporation may indemnify any person who was or  is
a  party or  is threatened  to be  made a  party to  any threatened,  pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action  by or in the  right of the corporation)  by
reason  of the fact that he is or  was a director, officer, employee or agent of
the corporation, or is  or was serving  at the request of  the corporation as  a
director,  officer, employee or agent of another corporation, partnership, joint
venture, trust  or  other  enterprise, against  expenses  (including  attorney's
fees),  judgments, fines and amounts paid and settlement actually and reasonably
incurred by him in connection with such  action, suit or proceeding if he  acted
in  good faith and in a manner he reasonably believed to be in or not opposed to
the best interest of the corporation and, with respect to any criminal action or
proceeding, had no  reasonable cause to  believe his conduct  was unlawful.  Any
indemnification  shall  be made  by the  corporation only  as authorized  in the
specific case  upon  a  determination  that  indemnification  of  the  director,
officer, employee or agent is proper in the circumstances because he has met the
applicable  standard  of conduct.  Such  determination shall  be  made by  a (i)
majority vote of a  quorum consisting of  the directors who  are not parties  to
such  action, suit or proceeding; or (ii) if a quorum is not obtainable, or even
if obtainable  a quorum  of disinterested  directors so  direct, by  independent
legal counsel in a written opinion; or (iii) by the stockholders.
 
    The  Financial  Security  Certificate of  Incorporation  provides  that each
person who was or is  made a party or  is threatened to be  made a party to  any
suit  or proceeding by reason of the fact that he or she is or was a director or
officer of  Financial  Security or  was  serving  at the  request  of  Financial
Security  as a  director, officer  or employee  of another  corporation shall be
indemnified by Financial Security and held harmless by it to the fullest  extent
authorized by the DGCL. In addition, the DGCL provides that a director shall not
be  personally liable  to Financial  Security or  its stockholders  for monetary
damages for breach of fiduciary duty as a director, except for liability (i) for
any breach  of the  director's duty  of  loyalty to  Financial Security  or  its
stockholders;  (ii) for acts  or omissions not  in good faith  and which involve
intentional misconduct or a knowing violation  of loss; (iii) under Section  174
of  the DGCL;  or (iv) for  any transaction  from which the  director derives an
improper personal benefit.
 
ANTI-TAKEOVER STATUTES
 
    The IBCA contains  certain provisions  which are intended  to deter  certain
acquisitive  transactions. The  IBCA provides that  a corporation  may not enter
into a business  combination with a  holder of  fifteen percent or  more of  the
corporation's  outstanding voting shares (an "Interested Stockholder") for three
years after  the  transaction  pursuant  to which  such  stockholder  became  an
Interested  Stockholder,  unless:  (i)  the  Interested  Stockholder  had  board
approval for the business combination or  the transaction which resulted in  the
stockholder  becoming an Interested  Stockholder; (ii) upon  consummation of the
transaction  which   resulted  in   the  stockholder   becoming  an   Interested
Stockholder,  the  Interested  Stockholder  owned at  least  85  percent  of the
outstanding
 
                                      130
<PAGE>
voting stock of the corporation  not owned by (1)  directors or officers of  the
corporation  or (2) employee stock plans which do not allow individual employees
to decide confidentially whether to tender their shares; or (iii) subsequent  to
the  time  of the  transaction  which resulted  in  the stockholder  becoming an
Interested Stockholder, the  business combination  is approved by  the board  of
directors of the corporation and by two-thirds of the stockholders excluding the
Interested  Stockholder, directors  and officers  and non-confidential tendering
employee plans.  A  "business  combination"  is  defined  as  (x)  a  merger  or
consolidation  of the corporation with an  Interested Stockholder, (y) any sale,
lease, exchange, transfer or other disposition  of ten percent (10%) or more  of
the  assets of the  corporation determined on  a consolidated basis,  or (z) any
transaction which results in the issuance or transfer by the corporation of  any
shares  of  the corporation  to the  Interested  Stockholder subject  to certain
exceptions.
 
    In addition, the  IBCA provides that  a corporation may  not enter into  any
business  combination with a holder of ten  percent or more of the corporation's
outstanding voting shares unless: (i) such combination is approved by two-thirds
of the disinterested directors or by 80 percent of the outstanding shares and  a
majority  of the shares not  held by the 10 percent  stockholder; or (ii) a fair
price is paid for all shares acquired.
 
    Pursuant to the IBCA, a corporation may elect to not be subject to either of
the foregoing  statutes. To  date,  Pinnacle has  not  made such  election  and,
therefor, continues to be subject to these provisions.
 
    The  DGCL  also  contains certain  provisions  which are  intended  to deter
certain acquisition transactions. The DGCL  provides that a corporation may  not
enter into a business combination with an Interested Stockholder for three years
after  the transaction pursuant  to which such  stockholder became an Interested
Stockholder, unless (i) the  Interested Stockholder had  board approval for  the
business  combination  or  the  transaction which  resulted  in  the stockholder
becoming an Interested  Stockholder; (ii) upon  consummation of the  transaction
which  resulted  in  the  stockholder becoming  an  Interested  Stockholder, the
Interested Stockholder owned at least 85 percent of the outstanding voting stock
of the corporation not owned by (1) directors or officers of the corporation  or
(2)  employee  stock plans  which do  not allow  individual employees  to decide
confidentially whether to tender their shares;  or (iii) subsequent to the  time
of  the transaction  which resulted  in the  stockholder becoming  an Interested
Stockholder, the business combination is approved  by the board of directors  of
the  corporation and by two-thirds of  the stockholders excluding the Interested
Stockholder. The DGCL defines business combinations to include the  transactions
deemed  a business combination by the IBCA.  Pursuant to the DGCL, a corporation
may provide in its  charter or by-laws a  provision expressly providing that  it
shall  not be subject to the foregoing  statute. To date, Financial Security has
not made such election and, therefor, continues to be subject to the provisions.

                   PINNACLE BANC GROUP, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1)   ACCOUNTING POLICIES:
    The  consolidated financial statements of the Pinnacle Banc Group, Inc. (the
"Corporation") and Subsidiaries have been prepared in conformity with  generally
accepted  accounting  principles  and  reporting  practices  prescribed  for the
banking industry. The  Corporation is  a multi-bank  holding company  registered
under  the Bank Holding  Company Act and  is engaged in  the business of banking
through the  ownership of  subsidiary banks.  A description  of the  significant
accounting policies follows:
 
    (a)  CONSOLIDATION --
 
    The  consolidated financial  statements of the  Corporation and Subsidiaries
include the  accounts of  the Corporation  and its  subsidiaries, Pinnacle  Bank
("PB"),  Pinnacle Bank  of the  Quad-Cities ("PBQC"),  and Batavia  Savings Bank
("BSB"). Significant intercompany accounts and transactions have been eliminated
in the preparation of these statements.
 
    PB was formed through the merger of First National Bank of Cicero  ("FNBC"),
Berwyn  National Bank ("BNB"),  and First National Bank  in Harvey ("FNBH") with
and into Bank of  LaGrange Park ("BLGP")  on July 9, 1993.  Each of these  Banks
were  subsidiaries of the Corporation.  As part of the  merger, the name of BLGP
was changed to  Pinnacle Bank.  The transaction was  accounted for  in a  manner
similar to a pooling of interests.
 
    PBQC  was formed through  the merger of  The Henry County  Bank ("HCB") with
Bank of Silvis ("BOS") on December 7,  1992. HCB and BOS were each  subsidiaries
of  the Corporation. The transaction was accounted  for in a manner similar to a
pooling of interests.
 
    (b)  STATEMENTS OF CASH FLOWS --
 
    For purposes of reporting cash flows, cash and cash equivalents include cash
on hand, amounts  due from  banks, and  Federal funds  sold. Generally,  Federal
funds are sold for one-day periods.
 
     i.)  In  the consolidated  statements of  cash  flows, acquisitions  by the
Corporation are recorded as net cash from investing activities and, accordingly,
cash flows are net of the impact  of the acquisitions discussed below. In  1995,
Acorn  Financial Corp ("AFC") and its  subsidiary bank, Suburban Trust & Savings
Bank ("STSB") was purchased by the Corporation and cash of $23,413,897 was  paid
for  the acquisition. At the date of purchase, the balance sheet of AFC included
cash and cash  equivalents of  $8,614,094 resulting in  a net  cash position  of
$14,799,803.
 
    ii.)  In the  statements of  cash flows  for the  Parent Company  (Note 18),
acquisitions by  the  Corporation  are  recorded  as  net  cash  from  investing
activities  in the  amount of  the cash  paid for  the acquisitions  net of cash
acquired. In 1995, this amount was $23,413,897 for the acquisition of AFC.
 
    (c)  SECURITIES --
 
    Effective January  1,  1994,  the  Corporation  adopted  the  provisions  of
Statement  of Financial Accounting  Standards ("SFAS") No.  115, "Accounting for
Certain Investments in Debt and Equity  Securities". SFAS No. 115 addresses  the
accounting  and reporting of investments in  equity securities that have readily
determinable fair values and for all investments in debt securities.  Securities
are  to be classified in  three categories: held-to-maturity securities, trading
securities and available-for-sale securities.
 
    Upon adoption  of  SFAS  No.  115, all  securities  held  by  Pinnacle  were
classified  as available-for-sale.  As a result,  securities are  carried on the
balance  sheet  at  fair  value,   with  corresponding  (after  tax)   valuation
adjustments  included in stockholders' equity. The  adoption of SFAS No. 115 had
the effect of  increasing stockholders' equity  by approximately $6,800,000,  at
January 1, 1994.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
(1) ACCOUNTING POLICIES: (CONTINUED)
    Premium  and  discount  on securities  are  included in  interest  income on
securities over the  period from acquisition  to maturity or  earlier call  date
using  the level-yield  method. The  specific identification  method is  used to
record gains and losses on securities transactions.
 
    (d)  LOANS --
 
    Loans are stated net of unearned income. The unearned income on  installment
loans  is recognized  as interest income  over the  term of the  loans using the
sum-of-the-months-digits method,  which  does  not differ  materially  from  the
effective interest method.
 
    Loan  origination and  commitment fees  and certain  direct loan origination
costs are deferred and the net amount amortized as an adjustment of the  related
loan's  yield.  The  Corporation  generally  amortizes  these  amounts  over the
contractual life of the related loans.
 
    In  May  1993,  the  Financial  Accounting  Standards  Board  (FASB)  issued
Statement  of Financial Accounting  Standards No. 114,  "Accounting by Creditors
for Impairment of a Loan". This standard  was amended in October, 1994, by  SFAS
No.  118,  "Accounting  for  Creditors  for  Impairment  of  a  Loan  --  Income
Recognition and Disclosure".  SFAS No.  114 addresses the  accounting for  loans
when  it is probable that all principal and  interest amounts due on a loan will
not be  collected  in accordance  with  its contractual  terms  (i.e.  "impaired
loans").  Pursuant to SFAS No. 114, to  the extent the recorded investment of an
impaired loan exceeds the present value of the loan's expected future cash flows
or other  measures  of value,  a  valuation  allowance is  established  for  the
difference.  The  corresponding  allocation  or charge  will  be  to  either the
allowance for loan  losses or to  the provision for  loan losses,  respectively,
depending  on  the  adequacy  of  the overall  allowance  for  loan  losses. The
Corporation adopted SFAS No.  114 and SFAS  No. 118 effective  as of January  1,
1995.  There was no effect on the financial position and results of operation of
the Corporation upon adopting these standards.
 
    No changes  were  required  to  Pinnacle's  accounting  policies  to  loans,
charge-offs, and interest income as a result of adopting these Statements.
 
    (e)  ALLOWANCE FOR LOAN LOSSES --
 
    The  allowance for loan losses is  determined by management based on factors
such as past loan  loss experience, evaluation of  known and inherent losses  in
the  loan  portfolio,  prevailing  economic conditions,  and  other  factors and
estimates which  are  subject  to  change  over  time.  Management  adjusts  the
allowance  for loan losses by recording a provision for loan losses in an amount
sufficient to maintain the allowance at  a level commensurate with the risks  in
the  loan portfolio.  Loans are charged-off  when deemed to  be uncollectible by
management.
 
    (f)  PREMISES AND EQUIPMENT --
 
    Premises and equipment are stated at cost less accumulated depreciation. For
financial reporting purposes,  depreciation is computed  using a combination  of
the straight-line and accelerated methods over the estimated useful lives of the
assets.
 
    (g)  OTHER REAL ESTATE --
 
    Other  real  estate, included  in other  assets, includes  property acquired
through foreclosure or deed in lieu of foreclosure. Other real estate is carried
at the lower of cost or fair value. Losses arising at the time of acquisition of
property in full or partial satisfaction  of loans are recorded as loan  losses.
Subsequent  losses or  expenses on the  property are charged  to other expenses.
Income received on the property is recorded as an offset to expenses.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
(1) ACCOUNTING POLICIES: (CONTINUED)
    (h)  INCOME TAXES --
 
    The consolidated Federal income tax  return of the Corporation includes  the
accounts  of each  subsidiary bank. Under  the terms of  a tax-sharing agreement
with the Corporation, each subsidiary bank is required to pay to the Corporation
the Federal income tax liability computed as if the subsidiary bank were to file
a separate income  tax return. In  the event  of a separate  bank net  operating
loss, the Corporation shall remit to each subsidiary bank the appropriate amount
of  each refund.  The tax-sharing agreement  also includes a  provision that the
Corporation will indemnify each subsidiary bank against all tax liabilities  for
any  taxable year  in which  the subsidiary bank  joins with  the Corporation in
filing a consolidated return.
 
    Pinnacle adopted SFAS No. 109, "Accounting for Income Taxes", which modified
the provisions of SFAS No. 96, with  an effective date of January 1, 1993.  SFAS
No.  109  requires an  asset and  liability approach  for accounting  for income
taxes. Its objective is to recognize  the amount of taxes payable or  refundable
for the current year, and deferred tax assets and liabilities for the future tax
consequences  for items that have been recognized in the Corporation's financial
statements or tax  returns. The  measurement of  tax assets  and liabilities  is
based on enacted tax laws. Deferred tax assets are reduced, if necessary, by the
amount  of such benefits that are not expected to be realized based on available
evidence.
 
    The cumulative effect of the  adoption of SFAS No.  109 on periods prior  to
January  1,  1993  amounted to  a  benefit  of $1,700,000,  net  of  a valuation
allowance, which was recorded as a deferred tax asset.
 
    (i)  LONG-LIVED ASSETS --
 
    In March 1995, the Financial Accounting Standards Board issued Statement No.
121 "Accounting for the Impairment of Long-lived Assets and Long-lived Assets to
be Disposed of ("SFAS 121"). The Corporation is required to adopt the provisions
of SFAS 121 in 1996. Based  on information currently available, the  Corporation
does not expect the impact of adoption SFAS 121 to have a material effect on its
consolidated financial condition or results of operations.
 
    (j)  ESTIMATES --
 
    In   preparing  the  consolidated   financial  statements,  management  made
estimates and  assumptions that  affect  the amounts  reported therein  and  the
disclosures  provided.  These estimates  and assumptions  may change  and future
results could differ from those estimates and assumptions.
 
(2)   ACQUISITIONS:
    On January 6, 1995, the Corporation completed the acquisition of AFC and its
subsidiary STSB. The purchase price was  $23,413,897 in cash for all the  issued
and  outstanding shares of AFC. Funds to pay for the purchase were borrowed from
an unaffiliated bank. At the date of purchase, AFC was liquidated and concurrent
with the liquidations, STSB was merged into PB. As of the date of purchase,  AFC
had  total  assets  of  approximately  $144,000,000.  Goodwill  of approximately
$13,000,000 created in  the acquisition is  being amortized on  a straight  line
basis over fifteen years.
 
    This  transaction was accounted for using  the purchase method of accounting
and the excess of the aggregate purchase  price paid over the fair value of  the
net  assets acquired  consisted of goodwill.  The results of  operations of STSB
have been  included  in the  consolidated  financial statements  since  date  of
acquisition.  No pro forma financial information is presented for 1995 since the
acquisition closely

and $5,493,782, respectively. Goodwill is stated net of accumulated amortization
of  $17,465,633 and  $15,921,398 at  December 31,  1995 and  1994, respectively.
Goodwill represents the  excess of the  aggregate purchase price  paid over  the
fair value of the net assets received in the purchases of FNBC and BLGP in 1980,
FNBH in 1982, FNBC's purchase of Cicero State Bank ("CSB") in 1982, BOS in 1989,
BNB  and HCB in 1991, BSB in 1992,  and AFC in 1995. Goodwill is being amortized
on straight line and accelerated methods over  periods of 10 years to 20  years.
Amortization of goodwill amounted to $1,544,235 in 1995, $1,340,021 in 1994, and
$1,340,019 in 1993.

and $2,471,525  as  of December  31,  1995  and 1994,  respectively,  which  was
allocated  to values associated with the  acquired deposits of the Berwyn branch
of Olympic  Federal Savings  Association. Other  intangibles are  stated net  of
accumulated  amortization of  $1,278,375 and $937,475  at December  31, 1995 and
1994, respectively. Amortization of the deposit base intangible, which is  being

    At  December  31,  1995  and  1994,  securities  carried  at   approximately
$29,477,162  and $26,131,828,  respectively, were  pledged to  secure public and
trust deposits, securities  sold under  agreement to repurchase,  and for  other
purposes as required or permitted by law.
 
    The  mortgage-backed securities are  direct obligations of  U. S. Government
agencies and the floating rate collateralized mortgage obligations are primarily
secured by  obligations  of  U.  S.  Government  agencies.  In  the  opinion  of
management,  there were no material securities  held at either December 31, 1995
or 1994, which constituted an unusual credit risk for the Corporation.

    The  balance of impaired  loans at December 31,  1995, was $5,739,714, while
the average balance for the year was $5,992,000. No portion of the allowance for

    Loan concentrations are defined  as amounts loaned to  a multiple number  of
borrowers  engaged in similar activities, which would cause them to be similarly
impacted by  economic  or  other  conditions. Although  the  Corporation  has  a
diversified  loan portfolio,  a substantial natural  geographic concentration of
credit risk exists within the Corporation's defined customer market areas. These
geographic  market  areas  include  the   Chicago  metropolitan  area  and   the
Quad-Cities metropolitan area of Illinois and Iowa.

</TABLE>
 
    A valuation  allowance  is provided  when  the realization  potential  of  a
portion  of the deferred tax  asset cannot be determined  to be more likely than
not. The Corporation has established a valuation allowance for a portion of  its
Federal  and State tax net operating loss  carryforward. In 1995, a deferred tax
asset relating to an installment note sale, for which a valuation allowance  had
been  established,  was recognized.  This,  together with  establishment  of the
valuation allowance for the state  tax net operating loss carryforward  resulted
in  the change in the valuation allowance. Also included in the net deferred tax
asset is  the tax  effect of  the unrealized  gain on  securities which  is  not
recorded through the provision for taxes, but directly to Stockholders' Equity.
 
    The  net operating  loss carryforward  for Federal  purposes relates  to the
parent company  and  is subject  to  significant  limitation on  its  usage.  At
December  31,  1995, the  Federal net  operating  loss carryforward  amounted to
approximately $3,641,000 which expires,  if unused, in the  years 1999 to  2001.
The State net operating loss carryforward amounted to $23,549,000 which expires,
if unused, in the years 2010 and 2011.
 
    At  December 31, 1995, the Corporation had an alternative minimum tax credit
carryforward of approximately $1,284,000, which is not subject to expiration.

(8)  NOTES PAYABLE:
 
    The  Corporation has  financed acquisitions, purchases  of equity securities
and short-term  cash requirements  of the  parent company  with an  unaffiliated
bank.  At December 31, 1995, the borrowings are composed of a $23,000,000 demand
loan used for the acquisition of AFC and a $7,000,000 revolving line of  credit.
Total  outstandings were $20,600,000  at December 31,  1995 of which $20,000,000
related to the  AFC note. During  1994, the borrowings  of the Corporation  were
composed  of a  non-revolving note  and a  $10,000,000 revolving  line of credit
which was replaced by the aforementioned line of credit. Total outstandings were
$5,400,000 at December 31, 1994.
 
    These borrowings bear interest at a floating rate tied to the prime rate  or
LIBOR,  are due  on demand  and are  secured by  the common  stock owned  by the
Corporation of each subsidiary bank.
 
(9)  PROFIT-SHARING AND INCENTIVE PLANS:
 
    The  Corporation  maintains   a  trusteed,   profit-sharing  plan   covering
substantially  all employees who  have met age  and service requirements. Annual
contributions are made in accordance with  a resolution passed by the Boards  of
Directors  of the Corporation and each  subsidiary bank and amounted to $414,144
for 1995, $337,072 for 1994, and $339,259 for 1993.
 
    The Corporation and  each subsidiary  bank maintain  profit incentive  plans
which  are available to  certain key executives. Distributions  are based on the
performance levels of the Corporation and each subsidiary bank, and are  subject
to the Board of Directors' approval.
 
(10)  STOCK OPTION PLAN:
 
    In  April, 1990, the  shareholders approved the  1990 Incentive Stock Option
Plan ("1990 Plan"). The  1990 Plan covers key  employees of the Corporation  and
requires  that all options  be issued at an  option price at  least equal to the
fair market  value per  share of  the  Corporation's common  stock on  the  date
granted.  No options may be granted to any  individual who owns more than 10% of
the Corporation's common stock unless the grant  is at a purchase price of  110%
of the option's fair market value on the date of grant. Under the 1990 Plan, the
aggregate  number  of shares  which could  be issued  under options  are 246,666
shares.
 
    The Corporation previously  had an  incentive stock  option plan  originally
adopted  in 1981 ("Prior Plan") which terminated on December 31, 1990 in regards
to the issuance  of new  options. The  Prior Plan was  amended in  1988 and  the
options  previously  granted  by  companies  merged  into  the  Corporation were
converted into options to  purchase shares of  the Corporation. The  substantive
terms  of the Prior Plan were  the same as the 1990  Plan. Under the Prior Plan,
the aggregate number of shares which could be issued under options were  366,667
shares.  Upon adoption of  the 1990 Plan,  no additional option  shares could be
issued under the Prior Plan.

    In  1995  and  1993,  the  Corporation  derived  tax  deductions  from   the
disposition  of stock option shares by participants of the Prior Plan before the
expiration of defined holding periods for tax purposes. These tax deductions are
measured by the excess of the market value over the option price at the date  of
sale  by  the participant.  The related  tax benefit  is credited  to additional
paid-in capital. The Corporation makes  no charges against capital with  respect
to options granted.
 
    During  1993, individuals  exercised stock  appreciation rights  relating to
13,333 shares with an average grant value of $10.42 per share. Upon exercise  of
these stock appreciation rights, the Corporation paid compensation, the majority
of   which  was  previously  accrued,  to  the  individuals  holding  the  stock
appreciation rights in the amount of the difference between the market price  of
the  Corporation's common stock on the date  of exercise and the grant price. At
December 31, 1995 and 1994, no stock appreciation rights were outstanding.

transactions  may  be  expected  in the  future.  In  management's  opinion, all
outstanding loans,  commitments  and  deposit  relationships  included  in  such
transactions were made on substantially the same terms, including interest rates
and collateral, as those prevailing at the time for comparable transactions with
others,  and did not involve more than  a normal risk of collectibility or other
unfavorable features.
 
    One director of the  Corporation is a  partner in a  law firm that  provides
various  legal services  to the Corporation  and its subsidiary  banks. Fees for
these services were $250,128 in 1995, $262,040 in 1994, and $104,150 in 1993.
 
(13)  LITIGATION:
 
    During the first quarter of 1994, a judgment in the amount of $2,300,000 was
entered in the U. S. Bankruptcy Court against PB. The judgment is the result  of
a  suit filed  against PB by  a trustee of  a debtor in  bankruptcy. The trustee
claimed that  PB  honored  overdrafts  in  the  debtor's  bank  account  without
obtaining  prior  court  approval. The  amount  of the  judgment  represents the
cumulative amount  of all  payments received  by  PB from  the debtor  to  cover
overdrafts.  While PB appealed the decision in 1994, management, upon the advice
of legal  counsel,  settled the  case  for  $1,275,000 in  December,  1995.  The
settlement amount had been previously accrued.
 
    The  Corporation and the  subsidiary banks are subject  to other pending and
threatened legal actions which  arise in the normal  course of business. In  the
opinion of management, based upon consultation of legal counsel, the disposition
of  all outstanding  matters will  not have a  materially adverse  effect on the
consolidated financial position and results of operations.
 
(14)  DISCLOSURES ABOUT ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
    SFAS No.  107,  "Disclosures  About Fair  Value  of  Financial  Instruments"
requires  the disclosure of the fair value of financial instruments for which it
is practicable to estimate that value,  and the disclosure of the method(s)  and
significant   assumptions  used  to   estimate  the  fair   value  of  financial
instruments. The following  methods and  assumptions were used  to estimate  the
fair value of each class of financial instruments for which it is practicable to
estimate that value:
 
    (a)    CASH AND  DUE FROM  BANKS,  FEDERAL FUNDS  SOLD AND  INTEREST BEARING
DEPOSITS --
 
    For these short-term instruments, the carrying value approximates fair value
because  these  instruments  are  short-term  in  nature  and  do  not   present
unanticipated credit concerns.
 
    (b)  SECURITIES --
 
    For  debt securities and  equity securities available  for sale, fair values
are based on quoted market prices or dealer quotes. If a quoted market price  is
not  available, fair value  is estimated using quoted  market prices for similar
instruments or carried at cost.
 
    (c)  LOANS --
 
    The fair value of  performing loans is  calculated by discounting  scheduled
cash  flows through the estimated maturity using estimated market discount rates
that reflect  the  credit and  interest  rate risk  inherent  in the  loan.  The
estimate of maturity is based on the Corporation's and the industry's historical
experience  with repayments for each loan classification, modified, as required,
by an estimate of the effect of current economic and lending conditions.
 
    Fair value for significant impaired loans  is based on estimated cash  flows
which are discounted using a rate commensurate with the risk associated with the
estimated  cash  flows.  Assumptions  regarding  credit  risk,  cash  flows, and
discount rates are  judgmentally determined using  available market  information
and specific borrower information.

                   PINNACLE BANC GROUP, INC. AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
    (d)  DEPOSIT LIABILITIES --
 
    The  fair value  of deposits with  no stated maturity,  such as non-interest
bearing deposits,  savings, and  NOW  accounts, and  money market  and  checking
accounts,  is equal to the amount payable on demand as of December 31, 1995. The
fair value  of certificates  of deposit  is  based on  the discounted  value  of
contractual cash flows. The discount rate is estimated using the rates currently
offered for deposits of similar remaining maturities.
 
    (e)  SHORT TERM BORROWINGS AND NOTES PAYABLE
 
    Rates  currently available to the Corporation and Subsidiaries for debt with
similar terms  and remaining  maturities  are used  to  estimate fair  value  of
existing debt.
 
    (f)  UNRECOGNIZED FINANCIAL INSTRUMENTS
 
    The  fair value of unrecognized  financial instruments including commitments
to extend  credit,  standby  letters  of credit  and  financial  guarantees  are
insignificant and, therefore, not presented.
 
    The  estimated  fair values  of the  Corporation's financial  instruments at
December 31 are as follows:

    (g)  LIMITATIONS
 
    Fair value estimates are made at a specific point in time, based on relevant
market  information  and  information  about  the  financial  instrument.  These
estimates do not reflect any premium or discount that could result from offering
for sale at one time the Corporation's entire holdings of a particular financial
instrument.  Because no actively traded market  exists for a significant portion
of the Corporation's financial  instruments, fair value  estimates are based  on
judgments regarding future

<PAGE>

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
expected  loss experience, current economic  conditions, risk characteristics of
various financial instruments, and other factors. These estimates are subjective
in nature and involve  uncertainties and matters  of significant judgments  and,
therefore,  cannot be  determined with  precision. Changes  in assumptions could
significantly affect these estimates.
 
    Fair  value  estimates  are  based  on  existing  on  and  off-balance-sheet
financial  instruments.  The  disclosures  do  not  address  the  value  of  the
Corporation's other types of recognized and unrecognized assets and  liabilities
or  the value of anticipated future business. In addition, the tax ramifications
related to  the  realization of  the  unrealized gains  and  losses can  have  a
significant  effect on fair value estimates and have not been considered in many
of the estimates.
 
(15)  FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK:
 
    The Corporation  has, through  its subsidiary  banks, financial  instruments
with  off-balance-sheet risk made in  the normal course of  business to meet the
financing  needs  of   its  customers.  These   financial  instruments   include
commitments   to  extend  credit,  standby   letters  of  credit  and  financial
guarantees. Those instruments  involve, to varying  degrees, elements of  credit
risk   in  excess  of  the  amount  recognized  in  the  consolidated  financial
statements. The  contract amounts  of those  instruments reflect  the extent  of
involvement  the  subsidiary  banks  have  in  particular  classes  of financial
instruments. The Corporation is not using any derivative products for hedging or
other purposes.
 
    The subsidiary banks' exposure to credit loss in the event of nonperformance
by the other party to the financial instrument for commitments to extend  credit
and standby letters of credit and financial guarantees written is represented by
the  contractual amount of those instruments. Each subsidiary bank uses the same
credit policies in making commitments and conditional obligations as it does for
on-balance-sheet instruments.  At December  31, 1995  and 1994,  the  subsidiary
banks had the following financial instruments with off-balance-sheet risk:

Commitments to extend credit...............................................  $   70,651,000  $   59,326,000
Standby letters of credit and financial guarantees written.................       2,982,000       3,412,000
</TABLE>
 
    Commitments to extend credit are agreements to lend to a customer as long as
there  is no violation of any condition established in the contract. Commitments
generally have  fixed expiration  dates  or other  termination clauses  and  may
require  payment of a fee. Since many  of the commitments are expected to expire
without being  drawn  upon, the  total  commitment amounts  do  not  necessarily
represent   future  cash  requirements.  Each  subsidiary  bank  evaluates  each
customer's creditworthiness on  a case-by-case basis.  The amount of  collateral
obtained,  if deemed necessary, by each subsidiary bank upon extension of credit
is based on management's credit evaluation of the counterparty. Collateral  held
varies  but  may include  accounts  receivable, inventory,  property,  plant and
equipment, and income-producing commercial properties.
 
    Standby letters of credit and  financial guarantees written are  conditional
commitments  issued by  the subsidiary banks  to guarantee the  performance of a
customer to a  third party.  Those guarantees  are primarily  issued to  support
public  and private financing arrangements for a  period of less than two years.
The credit risk involved in issuing letters of credit is essentially the same as
that involved in extending  loan facilities to  customers. Each subsidiary  bank
holds  collateral supporting  those commitments  for which  collateral is deemed
necessary.

(16)  REGULATORY REQUIREMENTS:
 
    The subsidiary banks are  subject to Federal and  state laws which  restrict
the  payment of  dividends to the  Corporation. Based on  these restrictions, at
January  1,  1996,  the  subsidiary  banks  could  have  declared  approximately
$2,715,000 in dividends without requesting approval of the applicable Federal or
state regulatory agency.
 
    Based  on the types and amounts of  deposits received, banks are required to
maintain non-interest bearing cash balances  in accordance with Federal  Reserve
Bank  reserve  requirements. At  December 31,  1995  and 1994,  the non-interest
bearing cash balances maintained to  meet reserve requirements were  $10,527,000
and $7,199,000, respectively.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders and the Board of Directors
of Pinnacle Banc Group, Inc.
 
    We  have audited  the accompanying  consolidated balance  sheets of Pinnacle
Banc Group, Inc. (an Illinois Corporation)  and Subsidiaries as of December  31,
1995  and 1994,  and the related  consolidated statements of  income, changes in
stockholders' equity and cash flows  for each of the  three years in the  period
ended  December 31, 1995.  These financial statements  are the responsibility of
the Corporation's management.  Our responsibility  is to express  an opinion  on
these  financial statements based on  our audits. We did  not audit the December
31, 1993 financial statements of Batavia Savings Bank, which statements  reflect
assets  of 10 percent of the  consolidated totals. Those statements were audited
by other auditors whose report has been furnished to us and our opinion, insofar
as it relates to the  amounts included for that entity,  is based solely on  the
report of the other auditors.
 
    We  conducted  our audits  in  accordance with  generally  accepted auditing
standards. Those standards require that we plan and perform the audit to  obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits and the report of other auditors provide a reasonable
basis for our opinion.
 
    In  our opinion, based  on our audit  and the report  of other auditors, the
consolidated financial  statements  referred to  above  present fairly,  in  all
material  respects,  the financial  position of  Pinnacle  Banc Group,  Inc. and
Subsidiaries as  of  December  31, 1995  and  1994,  and the  results  of  their
operations  and  cash flows  for each  of the  three years  in the  period ended
December 31, 1995, in conformity with generally accepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
THREE MONTHS ENDED MARCH 31, 1996
 
NOTE 1
    The  accompanying  unaudited  consolidated  financial  statements  have been
prepared in accordance with generally accepted accounting principles (GAAP)  for
interim  financial  information and  with the  instructions  to form  10-QSB and
Article 10  of regulation  S-X. Accordingly,  they  do not  include all  of  the
information and notes required by GAAP for complete financial statements. In the
opinion  of  management, all  adjustments (consisting  of only  normal recurring
accruals) necessary for a fair presentation have been included.
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles and  with general  practices within  the thrift
industry requires management to make  estimates and assumptions that affect  the
reported  amounts of assets and liabilities, disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts  of
revenue  and  expenses during  the reporting  period.  The actual  results could
differ from these estimates. Areas  involving the use of management's  estimates
and  assumptions, and  which are  more susceptible to  change in  the near term,
include the allowance for loan losses,  the realization of deferred tax  assets,
fair  value  of  certain  securities,  including  FHA  Title  I  securities  and
collateralized mortgage  obligations, the  determination and  carrying value  of
impaired loans, the carrying value of loans held for sale, the carrying value of
other real estate, the fair value of mortgage servicing rights as they relate to
the   limited  partnership,   and  the   determination  of  other-than-temporary
reductions in the fair value of securities.
 
    The results of operations  and other data for  the three months ended  March
31,  1996 are not necessarily indicative of results that may be expected for the
entire fiscal year ending December 31, 1996.
 
    The unaudited  consolidated financial  statements  include the  accounts  of
Financial  Security  Corp.  (the  "Company") and  its  wholly  owned subsidiary,
Security Federal Savings  and Loan Association  of Chicago (the  "Association"),
and  subsidiaries. All material intercompany accounts and transactions have been
eliminated in consolidation.
 
NOTE 2
 
    OTHER EVENTS.  On April 22, 1996, the Company entered into an Agreement  and
Plan  of Merger  (the "Agreement") with  Pinnacle Banc  Group, Inc. ("Pinnacle")
pursuant to which  Pinnacle will acquire  the Company with  the Company  merging
into  Pinnacle. The Company's wholly-owned  subsidiary, Security Federal Savings
and Loan  Association  of Chicago  will  be held  as  a separate  subsidiary  of
Pinnacle.
 
    Under the terms of the Agreement, holders of the Company's common stock will
receive  $28.50,  subject to  adjustment, in  cash, Pinnacle  common stock  or a
combination thereof for each share.
 
    The Agreement is subject to approval by the shareholders of the Company  and
Pinnacle and the approval of the appropriate regulatory authorities.
 
NOTE 3
    Earnings per share of common stock for the quarter ended March 31, 1996 have
been determined by dividing net income by 1,571,791 primary shares and 1,579,198
fully  diluted shares  respectively, the  weighted average  number of  shares of
common stock  and  common  stock  equivalents  outstanding.  Stock  options  are
regarded  as  common  stock  equivalents and  are  therefore  considered  in the
earnings per share calculations. Common stock equivalents are computed using the
treasury stock method. (See Exhibit 11.0).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
THREE MONTHS ENDED MARCH 31, 1996
 
NOTE 4  RECAPITALIZATION OF SAIF AND OTHER LEGISLATIVE INITIATIVES
    Legislative  initiatives  regarding  the  recapitalization  of  the  Savings
Association Insurance Fund ("SAIF") of the Federal Deposit Insurance Corporation
("FDIC"), deposit insurance premiums, FICO bond interest payments, the merger of
SAIF  and Bank Insurance Fund  ("BIF"), financial industry regulatory structure,
bad debt recapture and  revision of thrift and  bank charters are still  pending
before  Congress.  Management  cannot  predict  the  ultimate  impact  any final
legislation or  regulatory  actions may  have  on the  operations  of  Financial
Security.  Without passage of legislation  addressing the FDIC insurance premium
disparity, Security Federal, like  other thrifts, will  continue to pay  deposit
insurance  premiums significantly  higher than  banks. As  long as  such premium
differential continues, it may have adverse consequences on Financial Security's
earnings and  Financial Security  may  be placed  at a  substantial  competitive
disadvantage to commercial banking organizations insured by the BIF.
 
NOTE 5  SFAS NO. 122
    On  January 1,  1996, Financial  Security adopted  a Statement  of Financial
Accounting Standards No. 122, "Accounting for Mortgage Servicing Rights ("MSRs")
(an amendment to  Statement 65)." SFAS  122 provides for  the capitalization  of
MSRs  when mortgage loans are either  originated or purchased and the underlying
loan is  sold or  securities with  the MSR  retained. The  statement applies  to
servicing  rights resulting from mortgage loans only and is effective for fiscal
years starting  after  December 15,  1995.  Security Federal  is  currently  not
originating  mortgage loans for sale and therefore  the adoption of SFAS 122 did
not have a material impact on Financial Security.
 
NOTE 6  SFAS NO. 123
    During 1995, the FASB issued Statement No. 123, "Accounting for  Stock-Based
Compensation"  which provides  new accounting  guidelines over  the treatment of
employee stock options. The Statement gives entities a choice of either adopting
a new fair value method of  accounting for employee stock options and  expensing
any  related compensation costs in the  income statement, or continuing to apply
Accounting Principles Board Opinion No. 25  and provide pro forma disclosure  of
the  effect  of  the fair  value  method  within the  financial  statements. The
Statement is effective  for financial  statements beginning  after December  15,
1995. Financial Security currently intends to adopt the disclosure method of the
Statement.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        DECEMBER 31, 1995, 1994 AND 1993
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    NATURE  OF OPERATIONS:  Financial Security Corp. (the "Company") is a thrift
holding company organized under the laws  of the state of Delaware. Through  its
wholly  owned  subsidiary, Security  Federal Savings  and Loan  Association (the
"Association"), the  Company provides  financial services  to customers  located
primarily in Chicago and Cook County, Illinois, and, as discussed in Note 4, the
Association has also acquired loans outside of the Chicago area.
 
    BASIS  OF PRESENTATION:  The  accompanying consolidated financial statements
for the years ended  December 31, 1995,  1994 and 1993  include the accounts  of
Financial  Security Corp.,  the Association  and the  Association's wholly-owned
subsidiary, Security Federal Service  Corporation. All significant  intercompany
transactions and balances are eliminated in consolidation.
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted accounting  principles and  with general  practices within  the  thrift
industry  requires management to make estimates  and assumptions that affect the
reported amounts of assets and liabilities, disclosure of contingent assets  and
liabilities  at the date of the financial statements and the reported amounts of
revenue and  expenses during  the  reporting period.  The actual  results  could
differ from these estimates.
 
    Areas involving the use of management's estimates and assumptions, and which
are  more susceptible to change in the near term, include the allowance for loan
losses,  the  realization  of  deferred  tax  assets,  fair  value  of   certain
securities,  including  FHA  Title  I  securities  and  collateralized  mortgage
obligations, the  determination  and  carrying  value  of  impaired  loans,  the
carrying  value of loans held for sale, the carrying value of other real estate,
the fair  value of  mortgage servicing  rights  as they  relate to  the  limited
partnership,  and the  determination of  other-than-temporary reductions  in the
fair value of securities.
 
    STATEMENT OF CASH FLOWS:  For the  purpose of this statement, cash and  cash
equivalents   is  defined  to  include  cash   on  hand,  demand  balances,  and
interest-bearing deposits with financial  institutions with original  maturities
of  three months or less.  The Company reports net  cash flows for customer loan
transactions and deposit  transactions. Federal funds  sold are restricted  from
withdrawal because they are pledged against borrowings.
 
    SECURITIES:   Effective  January 1, 1994,  the Company  adopted Statement of
Financial Accounting Standards No. 115  (SFAS No. 115), "Accounting for  Certain
Investments  in Debt and Equity Securities".  SFAS No. 115 requires corporations
to classify debt and  equity securities as  either held-to-maturity, trading  or
available-for-sale.  The cumulative effect on stockholders' equity at January 1,
1994 of  adopting SFAS  No. 115  was included  as a  separate component  in  the
statement  of  stockholders'  equity  and represented  primarily  the  effect of
adjusting securities available-for-sale to  fair value, net  of income taxes  of
$35,000.  Securities are classified as  held-to-maturity when management has the
positive intent and  the Company  has the ability  to hold  those securities  to
maturity.  Accordingly, they  are stated at  cost, adjusted  for amortization of
premiums and  accretion of  discounts. All  other securities  are classified  as
available-for-sale  since the  Company may  decide to  sell those  securities in
response to changes in market interest rates, liquidity needs, changes in yields
or alternative investments and for  other reasons. These securities are  carried
at  fair value  with unrealized  gains and  losses charged  or credited,  net of
income taxes,  to a  valuation allowance  included as  a separate  component  of
stockholders'  equity. Realized gains and losses on disposition are based on the
net proceeds and the adjusted carrying amounts of the securities sold, using the
specific identification method.
 
    RECOGNITION OF  INCOME  ON LOANS:    Interest  on real  estate  and  certain
consumer  loans is accrued over  the term of the  loans based upon the principal
balance outstanding. Unearned interest on automobile and other consumer loans is
recognized over the loan term using the interest method.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                        DECEMBER 31, 1995, 1994 AND 1993
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Where serious doubt exists as  to the collectibility of  a loan, the accrual  of
interest   is  discontinued.   In  addition,  allowances   are  established  for
uncollected interest on mortgage loans with payments past due.
 
    ALLOWANCE FOR LOAN LOSSES:  Because some loans may not be repaid in full, an
allowance for loan losses is recorded.  Increases to the allowance are  recorded
by  a provision for loan  losses charged to expense.  Estimating the risk of the
loss and the amount of loss on any loan is necessarily subjective.  Accordingly,
the  allowance is  maintained by  management at  a level  considered adequate to
cover possible  losses  that  are  currently  anticipated  based  on  past  loss
experience,  general  economic conditions,  information about  specific borrower
situations including their financial position  and collateral values, and  other
factors  and estimates which  are subject to change  over time. While management
may periodically allocate portions  of the allowance  for specific problem  loan
situations,  the entire  allowance is  available for  any loan  charge-offs that
occur. A loan is charged-off against the allowance by management as a loss  when
deemed uncollectible, although collection efforts continue and future recoveries
may occur.
 
    Statement of Financial Accounting Standards (SFAS) No. 114 and SFAS No. 118,
"Accounting  by Creditors For Impairment  of a Loan" were  adopted at January 1,
1995. Under these standards, loans considered to be impaired, as defined in SFAS
No. 114 are reduced to the present value of expected future cash flows or to the
fair value of related  collateral, by allocating a  portion of the allowance  to
such  loans. If these allocations cause the allowance for loan losses to require
an increase, such increase is reported  as a provision for possible loan  losses
charged  to income. The adoption of SFAS No.  114 did not have a material effect
on the Company's financial position, results of operations or capital.
 
    LOAN ORIGINATION  FEES, COMMITMENT  FEES, AND  RELATED COSTS:   The  Company
defers  loan fees, net of certain direct  loan origination costs. The net amount
deferred is reported in  the statement of financial  condition as part of  loans
and  is recognized as interest income over the  term of the loan using the level
yield method.
 
    LOANS HELD FOR SALE:  Loans held for sale are carried at the lower of  cost,
less  applicable deferred loan  fees, or estimated fair  value in the aggregate.
Loans held for sale are  net of unearned discounts  of $392,000 and $463,000  at
December 31, 1995 and 1994, respectively.
 
    FORECLOSED  REAL ESTATE:  Real estate  acquired through foreclosure and deed
in lieu of foreclosure is transferred at the lower of estimated fair value  less
estimated  costs to dispose of  the property or the  related loan balance at the
date of  foreclosure. At  the time  of  transfer to  foreclosed real  estate,  a
charge-off  is recorded  to the loan  valuation allowance if  the estimated fair
value is less than its cost. Subsequent valuations are periodically performed by
management, and additional provisions  for loss are established  by a charge  to
non  interest expense if the carrying value  of a property exceeds its estimated
fair value less costs to dispose.
 
    LIMITED   PARTNERSHIP   INVESTMENTS   IN   PURCHASED   MORTGAGE    SERVICING
RIGHT:  Investments in limited partnerships to acquire mortgage servicing rights
(PMSR) are recorded on the equity method. Adjustments to the investment in PMSRs
are made on a quarterly bases to reflect equity in any income or loss. The PMSRs
acquired   by  the  limited  partnership  are  evaluated  for  impairment  using
discounted cash flows on a quarterly basis.
 
    In May 1995, the Financial Accounting Standards Board released SFAS No. 122,
"Accounting for  Mortgage  Servicing Rights".  SFAS  No. 122  requires  mortgage
banking enterprises to recognize the

rights  to service mortgage loans for others  as a separate asset, regardless of
the manner in which  such rights are  acquired. SFAS No.  122 applies to  fiscal
years  beginning after  December 15, 1995.  The limited partnership  has not yet
determined the impact of adopting SFAS No. 122.
 
    Cumulative undistributed earnings from these limited partnership investments
totaled $804,863 and $136,456 at December 31, 1995 and 1994.
 
    PREMISES AND EQUIPMENT:   Bank premises  and equipment are  stated at  cost,
less  accumulated depreciation and amortization. Provisions for depreciation and
amortization are computed on the straight-line method over the estimated  useful
lives of the assets. The cost of maintenance and repairs is charged to income as
incurred; significant repairs are capitalized.
 
    REAL  ESTATE  HELD FOR  DEVELOPMENT:   Real estate  held for  development is
carried at  the  lower of  cost,  including  capitalized holding  costs  or  net
realizable  value.  Real  estate held  for  development  is presented  net  of a
$316,000 and  $252,000  valuation  allowance  at December  31,  1995  and  1994,
respectively.
 
    INCOME  TAXES:   The provision  for income  taxes is  based on  an asset and
liability approach in  accordance with  SFAS No.  109. The  asset and  liability
approach requires the recognition of deferred tax liabilities and assets for the
expected  future tax consequences of  temporary differences between the carrying
amounts and the tax bases of assets and liabilities.
 
    EARNINGS PER SHARE:  Primary earnings per share for the years ended December
31, 1995, 1994, and 1993 were determined by dividing net income for the year  by
1,568,412, 1,632,453 and 1,715,555, respectively, the weighted average number of
shares  outstanding  for  each  year.  Fully-diluted  earnings  per  share  were
determined by dividing net income by 1,586,938, 1,632,453 and 1,721,511  shares,
respectively.  Stock options  are regarded as  common stock  equivalents and are
considered in  calculating both  primary and  fully-diluted earnings  per  share
calculations.  Common stock  equivalents are  computed using  the treasury stock
method.
 
    RECLASSIFICATIONS:  Certain 1994  and 1993 items  have been reclassified  to
conform to the 1995 presentation.

    In   December  of   1995  the   Company  reclassified   $24,600,000  of  its
held-to-maturity securities to available-for-sale in accordance with "A Guide to
Implementation of Statement 115  on Accounting for  Certain Investments in  Debt
and  Equity Securities". The  unrealized loss on  the securities transferred was
$34,472.
 
    The Company's investment in FHA Title 1 mortgage-backed securities is net of
a specific loss allowance of $57,000 and $315,000 at December 31, 1995 and 1994,
respectively.  The  allowance  has  been  established  by  management  to  cover
estimated  losses, which includes all loans greater than 90 days delinquent less
available insurance allowance.  During 1995, underlying  collateral of  $480,000

was  charged  off through  the allowance.  Currently,  the Company  is receiving
partial principal and interest  payments. This investment  has no liquid  market
and the value is impaired due to high delinquency and loss rates. The investment
is currently accounted for on a cash basis and fair value has been determined by
management based on estimates of future cash flows.
 
    The  amortized  cost  and  fair  value  of  securities  held-to-maturity  by

    Effective  January  1,  1995,  the Company  adopted  Statement  of Financial
Accounting Standard  No.  114  (SFAS  No. 114),  "Accounting  by  Creditors  for
Impairment  of a Loan",  and Statement of Financial  Accounting Standard No. 118
(SFAS No.  118), "Accounting  by Creditors  for Impairment  of a  Loan -  Income
Recognition  and  Disclosure". Under  these  standards, loans  considered  to be
impaired, as  defined in  SFAS No.  114, are  reduced to  the present  value  of
expected  future cash flows or  to the fair value  of the related collateral, by
allocating a portion of the allowance for  loan losses to such loans. There  was
no material effect on 1995 earnings as a result of adopting SFAS No. 114. During
1995,  concurrent with the adoption of SFAS 114, all loans previously classified
as in-substance foreclosures were transferred  back to loans. The  corresponding
valuation  allowances  were transferred  to the  allowance  for loan  losses. At
December 31, 1995,  the Company's gross  carrying amount of  impaired loans  was
$715,696  and the allowance for loan losses  allocated to impaired loans was $0.
During 1995, the average balance of impaired loans was $801,000.

          MORTGAGE SERVICING RIGHTS
    During 1995 and 1994, the Company invested in two limited partnerships, each
with  several equity investors, whose business  activity is to acquire purchased
mortgage servicing  rights (PMSRs).  The  purchase of  the servicing  rights  is
leveraged  on a  1:1 ratio. At  the end of  five years,  or at such  time as the
investors agree, the servicing rights will be sold and the proceeds divided  pro
rata  among the investors. All purchases of servicing rights must be approved by
all equity investors and meet certain agreed-upon guidelines. The administration
and servicing of the purchased portfolios  in each partnership are performed  by
Dovenmuehle  Mortgage, Inc., the general partner of each limited partnership. As
of December 31, 1995 and 1994, the Company has an investment of $8.6 million and
$7.8 million, respectively,  in two  limited partnerships  which have  purchased
PMSRs.  The Company's investment represents  an equity interest of approximately

    The Association adopted a collateral pledge agreement and agreed to keep  on
hand,  free of all other pledges,  liens, and encumbrances, first mortgages with
unpaid principal balances aggregating  no less than  167.67% of the  outstanding
secured  advances from the Federal  Home Loan Bank of  Chicago. All stock in the
Federal Home Loan Bank of Chicago  is also pledged as additional collateral  for
advances.
 
    In  1992, the Association  established a leveraged  Employee Stock Ownership
Plan (ESOP). This plan was funded by the proceeds from a $1,203,480 loan from  a
third-party  lender at a  rate of 5.70%  as of December  31, 1992 (federal funds
rate  plus  2.70%),  with  principal  and  interest  payable  in  28   quarterly
installments  maturing in December 1999. The  loan is secured by the unallocated
common stock the Company purchased with the  loan and federal funds sold to  the
third  party in the  amount of $746,000.  The Association has  committed to make
contributions to the ESOP sufficient to allow the ESOP to fund its debt  service
requirements on the loan.

and  federal funds sold approximates fair value  due to the short period of time
between origination of the instruments and their expected realization.
 
    SECURITIES HELD-TO-MATURITY  AND SECURITIES  AVAILABLE-FOR-SALE:   The  fair
value  of these financial instruments was  estimated using quoted market prices,
where applicable. No quoted market prices  were available on the investments  in
collateralized  mortgage obligations and FHA  Title 1 mortgage-backed securities
due to  no liquidity  in the  market for  these securities.  The fair  value  of
financial  instruments with no quoted market  prices was estimated by management
based on their opinion  of the ultimate realization  of principal and  interest.
Special  write-downs have been  taken on these  financial instruments to reflect
management's estimate of fair value.
 
    LOANS RECEIVABLE:  Fair  values are estimated for  portfolios of loans  with
similar  financial  characteristics.  Loans  are  segregated  by  type  such  as
one-to-four family, commercial, multi-family mortgage, and other consumer.  Each
loan category is further segmented into fixed and adjustable rate interest terms
and by performing and nonperforming categories.
 
    The  fair value of  performing loans, except  residential mortgage loans, is
calculated by discounting  scheduled cash flows  through the estimated  maturity
using  estimated market discount rates that reflect the credit and interest rate
risk inherent in the loan.  The estimate of maturity  is based on the  Company's
historical experience with repayments for each loan classification, modified, as
required,  by  an  estimate  of  the  effect  of  current  economic  and lending
conditions. For performing residential

NOTE 10 -- FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)
mortgage loans, fair value  is estimated by  discounting contractual cash  flows
adjusted for prepayment estimates using discount rates based on secondary market
sources  adjusted to reflect  differences in remaining  maturities and servicing
and credit costs.
 
    Fair value  estimates  for significant  non-performing  loans are  based  on
estimated  cash flows, which  are discounted using a  rate commensurate with the
risk associated  with the  estimated cash  flows. Assumptions  regarding  credit
risk, cash flows, and discount rates are judgmentally determined using available
information and specific borrower information.
 
    LOANS HELD FOR SALE:  Fair values of loans held for sale are estimated based
on quoted prices.
 
    ACCRUED  INTEREST RECEIVABLE  AND PAYABLE:   The  carrying value  of accrued
interest receivable and payable approximates fair value due to the fairly  short
period of time between accrual and expected realization.
 
    DEPOSITS:   The  estimated fair value  of deposits with  no stated maturity,
such as passbook, NOW, and money market accounts, is equal to the amount payable
on demand. The fair  value of deposits  with stated maturities  is based on  the
discounted value of contractual cash flows. The discount rate is estimated using
the rates currently offered for deposits of similar remaining maturities.
 
    BORROWED  FUNDS:   The fair value  of variable  rate borrowings approximates
carrying value due to the relatively  short period of time until their  expected
repricing  date. The fair value of fixed rate borrowings is the present value of
the contractual cash flows, discounted by  the current rate offered for  similar
remaining maturities.
 
    OFF-BALANCE-SHEET  FINANCIAL  INSTRUMENTS:   Fair  values for  the Company's
off-balance-sheet financial instruments are  based on current settlement  values
or  fees currently charged to enter into similar agreements, taking into account
the remaining term of  agreements and the  counterparties' credit standing.  The
fair value of these financial instruments is not material.

realized  based  on  historical  taxable income  levels  and  anticipated future
earnings and taxable  income levels. The  valuation allowance as  of January  1,
1995  was $505,000 and such  allowance decreased by $493,000  for the year ended
December 31, 1995.
 
    Retained earnings at December 31, 1995 includes approximately $5,513,000 for
which no provision for federal  or state income tax  has been made. This  amount
represents  allocation of income  to bad debt deductions  for tax purposes only.
Reduction of amounts so  allocated for purposes other  than tax bad debt  losses
will  create income  for tax purposes  only, which  will be subject  to the then
current federal and state  corporate income tax  rates. The unrecorded  deferred
tax  liability  on  the above  amount  at  December 31,  1995  was approximately
$2,136,000.

    On December  29,  1992, the  Association  converted from  a  federal  mutual
savings  association  to a  federal stock  savings association  and concurrently
became a wholly-owned subsidiary of the Company.
 
    As part of the conversion, the Association established a liquidation account
for the benefit of eligible depositors as of December 31, 1990, the  eligibility
record date, who continued to maintain deposits in the Association following the
conversion.  The initial  balance of  the liquidation  account was  equal to the
retained earnings of  the Association as  of December 29,  1992. The balance  in
this  account decreases each year in  which deposit balances of eligible account
holders decline.  In  the  unlikely  event of  a  complete  liquidation  of  the
Association,  each eligible depositor who has  continued to maintain deposits in
the  Association  following  the  conversion  will  be  entitled  to  receive  a
liquidation   distribution  from   the  liquidation  account,   based  on  their
proportionate share of the  then total remaining  qualifying deposits, prior  to
any  distribution to  the Company  as the  sole shareholder  of the Association.
Dividends cannot be  paid from  retained earnings allocated  to the  liquidation
account.
 
    The  Office of Thrift Supervision (OTS) imposes limitations upon all capital
distributions by savings institutions, including cash dividends. An  institution
that exceeds fully phased-in capital

1995, approximately $5,139,000  was available  for payment of  dividends by  the
Association to the Company.
 
NOTE 13 -- EMPLOYEE BENEFIT PLANS
 
    PENSION  PLANS:    The  Association  maintains  a  qualified noncontributory
defined benefit pension plan  (Regular Plan) covering  substantially all of  its
full-time  employees employed more than six months and over 20-1/2 years of age,
including part-time employees working over 1,000 hours per year. The Association
also established a Supplemental Retirement Agreement (Supplemental Plan) in 1992
with one officer of  the Association to  provide supplemental retirement,  death
and  disability benefits. The Supplemental Plan  is designed to provide benefits
for the difference between the maximum benefits available under the pension plan
and the actual benefits earned. The Association's policy is to fund the  minimum
contribution  required by  the Employee Retirement  Income Security  Act of 1974
using the entry-age normal aggregate cost method.
 
    The pension plans' financial data are  summarized as follows for plan  years
ending December 31, 1995 and 1994:

    EMPLOYEE STOCK  OWNERSHIP  PLAN:   In  conjunction  with  the  Association's
conversion,  the Association formed an Employee Stock Ownership Plan (ESOP). The
ESOP covers substantially all employees with more than six months of  employment
who have attained age 20-1/2. Benefits become 20% vested after the third year of
credited service, with an additional 20% vesting each year thereafter until 100%
vesting after seven years.
 
    In  1992, the ESOP borrowed $1,203,480  from an unrelated third-party lender
to purchase 120,348 shares of the common stock issued in the conversion.  Shares
purchased  by  the ESOP  are held  in  a suspense  account for  allocation among
participants as the  loan is paid.  In November of  1993, Statement of  Position
93-6 (SOP 93-6), "Employer's Accounting for Employee Stock Ownership Plans", was
issued.  SOP 93-6  is applicable for  fiscal years beginning  after December 15,
1993. The Company is not required to adopt the provisions of SOP 93-6, since all
shares were acquired before December 31,  1992. The Company will make  scheduled
contributions  to  the ESOP  sufficient to  service the  amounts borrowed  in 28
quarterly installments. The  unpaid balance  of the  ESOP has  been included  in
borrowed  funds  on  the  consolidated statements  of  financial  condition, and
stockholders' equity has  been reduced by  a similar amount.  The Company  makes
annual contributions to the ESOP

debt  equal to the ESOP's debt service  less dividends received by the ESOP. All
dividends received  by the  ESOP on  unallocated  shares are  used to  pay  debt
service.  The ESOP  shares are  pledged as collateral  for its  debt, along with
federal funds sold in the amount of $746,000. Compensation expense is recognized
as the ESOP debt is  paid. Contributions of $179,362  and $224,598 were made  to
the  ESOP to fund principal  and interest payments for  the years ended December
31, 1995 and 1994, respectively.

    SUPPLEMENTAL  RETIREMENT  PLAN:    In  conjunction  with  the  Association's
conversion, the Association formed a Supplemental Employee Stock Retirement Plan
to  provide certain key  employees with stock  benefits in the  event that these
employees retire prior to the expiration of the ESOP's term loan. The purpose of
this Supplemental  Employee Stock  Retirement Plan  is to  compensate these  key
employees  by providing  them with benefits  they would have  received under the
ESOP had they remained with  the Association until all  shares held in the  ESOP
suspense  account for their benefit were fully allocated. Supplemental ESOP plan
expense was $90,000 for  the year ended  December 31, 1994.  As of December  31,
1994,  the entire liability had been accrued  and no additional expense has been
recognized.
 
    RECOGNITION AND  RETENTION PLANS:   In  conjunction with  the  Association's
conversion,  the Association formed four  Recognition and Retention Plans (RRPs)
for the  benefit  of directors  and  officers of  the  Company as  a  method  of
providing  such persons a  proprietary interest in the  Company and to encourage
such persons to remain  with the Company. The  Company awarded 68,772 shares  of
the common stock issued in the conversion. Awards of common shares become vested
at  a rate of 20% per year after the first year from the date of the award. Upon
conversion, 63,270 shares of common stock were awarded.
 
    During 1995 a  new RRP  for the  benefit of  Directors and  officers of  the
Company  was  approved. This  plan  allows the  Company  to award  up  to 62,655
additional shares.  The Company  contributed $74,280  to purchase  3,714  shares
awarded in 1995. These awards vest at a rate of 20% per year.
 
    The  aggregate purchase price of the common shares awarded will be amortized
to compensation expense  as the Company's  eligible participants become  vested.
The  unamortized cost of the  RRPs is reflected as  a reduction to stockholders'
equity. Shares vested at  December 31, 1995  and 1994 were  14,218 and 15,951  ,
respectively. At December 31, 1995, 29,668 shares were unearned.
 
    INCENTIVE  STOCK OPTION  PLAN:   In 1992,  the Company  adopted an incentive
stock option plan (Incentive Plan) for the benefit of employees of the  Company.
The  number of options authorized under the  Incentive Plan is 103,155 shares of
the common stock issued  in the conversion. All  of the authorized options  were
granted  in 1992. Options become exercisable at a rate of 20% per year after one
year from the date of grant. The option exercise price must be at least 100%  of
the fair market

value  of the  common stock  on the date  of grant,  and the  option term cannot
exceed 10  years. Upon  conversion, all  Incentive Plan  options for  shares  of
common stock were granted at an exercise price of $10 per share.
 
    During  1995, a new option plan for the benefit of Directors and Officers of
the Company was approved.  This plan allows an  additional 93,983 options to  be
awarded  at 100% of fair value at the date of the grant and are exercisable at a
rate of 20%  per year after  one year from  the date of  the grant. The  Company
awarded  9,284 options during 1995  at an exercise price  of $16.75 per share of
common stock.
 
    DIRECTORS STOCK OPTION PLAN:   In 1992, the  Company adopted a stock  option
plan  for the benefit of nonemployee  directors (Directors Plan) of the Company.
The number of options  authorized under the Directors  Plan is 68,770 shares  of
common stock issued in the conversion.
 
    Options become immediately exercisable upon grant. The option exercise price
must  be at least 100% of the fair market  value of the common stock on the date
of grant, and the option term generally cannot exceed 10 years. Upon conversion,
55,016 options were  granted at an  exercisable price of  $10 per share.  During
1995,  the remaining 13,754 options were granted at an exercise price of $15 per
share.

Incentive Plan and Directors Plan is as follows:

NOTE 14 -- FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK
    The  Company is a party to financial instruments with off-balance-sheet risk
in the normal course of  business to meet the  financing needs of its  customers
and  to  reduce  its  own  exposure to  fluctuations  in  interest  rates. These
financial instruments  include  commitments  to extend  credit,  and  previously
approved  unused lines of credit. Those instruments involve, to varying degrees,
elements of credit and interest-rate risk in excess of the amount recognized  in
the statement of financial condition.
 
    The  Company's exposure to credit loss in the event of nonperformance by the
other party is represented by the  contractual amount of those instruments.  The
Company uses the same credit policies in making commitments as it does for loans
recorded in the statement of financial condition.

    At December 31, 1995 and 1994, these financial instruments are summarized as
follows:

Off-balance-sheet financial instruments whose contract amounts represent credit risk
  Commitments to extend credit
    Fixed rate mortgage loans.........................................................  $   863,000  $   2,151,000
    Unused lines of credit............................................................      870,000        731,000
</TABLE>
 
    Fixed  rate commitments have rates ranging from  7.00% to 9.00% and 7.25% to
11.50% at December 31, 1995 and 1994, respectively. The commitments are all  due
to  expire within 90 days  of issuance. Since certain  commitments to make loans
and fund lines of  credit and loans  in process expire  without being used,  the
above  amounts do not  necessarily represent future  cash commitments. No losses
are anticipated as a result of these transactions.
 
    The  Company's   loan  portfolio   has   a  substantial   concentration   of
out-of-market  purchased  and participation  loans. See  Note 4  regarding these
concentrations within the loan portfolio.
 
    In 1991, the Association became a 12.5% participant in certain aspects of  a
rehabilitation  project  for  low income  housing  in  the City  of  Chicago. In
addition, in 1991, the Association became a limited partner in a  rehabilitation
project  whereby it has made capital contributions approximating $751,298, which
represents a 13.96% interest in the  rehabilitation project. The purpose of  the
investment  is to qualify for low income housing tax credits which are estimated
to be approximately $1,676,000 over 15 years ending in 2005.
 
    The realization  of these  credits is  contingent upon  two factors.  First,
should the rehabilitation project be foreclosed upon and the participants unable
or unwilling to provide additional funds to the project, the partners would then
be  subject to  recapture of  a significant  portion of  the low  income housing
credits and would not be  able to claim any future  tax credits. Second, if  the
project  does not meet certain  set aside requirements and  the project fails to
qualify as low income housing at  any time during the 15-year compliance  period
ending  in the year 2005, the partners would then be subject to recapture rules.
The recapture rules could also apply if  other recapture events occur such as  a
change  in  ownership or  if a  limited partner  sold its  partnership interest.
Cumulative tax credits recognized by the Company total $395,000 through December
31, 1995.
 
NOTE 15 -- COMMITMENTS AND CONTINGENCIES
    The Company and the Association are parties to litigation and claims arising
in the  normal course  of business.  Management, after  consultation with  legal
counsel, believes that the liabilities, if any, arising from such litigation and
claims will not be material to the consolidated financial position.
 
    During  1994, the  Company entered  into a  pledge agreement  with Community
Investment Corporation.  The  Company has  agreed  to  fund up  to  $500,000  in
collateralized  trust notes. The  notes are secured by  mortgages for low income
housing. Through December 31, 1995, the Company has funded $152,909 in notes.
 
    As of January 1, 1995, the Association had $850,000 of federal funds pledged
as collateral for  its ESOP loan  with Nationar, the  ESOP lender. Nationar  was
seized  by the New York  State Banking Department on  February 6, 1995. The loan
and federal funds were  assumed by Northwest Savings  Bank under the same  terms
and collateral. In 1996, the loan was assumed by the Company.

NOTE 15 -- COMMITMENTS AND CONTINGENCIES (CONTINUED)
    The   Association  has  sold  two  parcels  of  foreclosed  real  estate  in
California, whereby the City of Los Angeles funds the sale through the  issuance
of bonds, but the seller has full recourse liability until the bonds are repaid.
The  Association currently  has a  contingent liability  of $670,000  related to
sales under this program.
 
    The Company entered into  a lease agreement on  December 1, 1994 for  branch
office  space. The  lease term  is 60 months.  Future minimum  lease payments at
December 31, 1995 are as follows:

    Rental expense for the year ended December 31, 1995 and 1994 was and $16,938
and $1,409.
 
    The deposits of savings associations such as the Association are insured  by
the  Savings  Association  Insurance  Fund (SAIF)  which,  along  with  the Bank
Insurance  Fund  (BIF),  is  administered  by  the  Federal  Deposit   Insurance
Corporation  (FDIC).  It  is  anticipated  that  SAIF  will  not  be  adequately
capitalized without a substantial increase in premium rates or the imposition of
special assessments or other significant developments, such as a merger of  SAIF
and BIF. A recapitalization plan under consideration by the Treasury Department,
the  FDIC , the Office  of Thrift Supervision (OTS)  and Congress provides for a
special assessment of .85% to .90%  to be imposed on all SAIF-insured  deposits.
No  assurance can be given, however, as  to whether a recapitalization plan will
be adopted.

The Board of Directors and Stockholders
Financial Security Corp.
Chicago, Illinois
 
We have audited the accompanying  consolidated statement of financial  condition
of   Financial  Security  Corp.  as  of  December  31,  1995,  and  the  related
consolidated statements of  earnings, stockholders' equity,  and cash flows  for
the  year then ended.  These financial statements are  the responsibility of the
Company's management.  Our responsibility  is  to express  an opinion  on  these
financial  statements based on our  audit. The consolidated financial statements
of Financial  Security Corp.  as  of December  31,  1994, and  the  consolidated
statements of earnings, stockholders' equity, and cash flows for the years ended
December  31, 1994 and  1993 were audited  by other auditors  whose report dated
February 27, 1995, included an explanatory paragraph which described the changes
in accounting for income taxes in 1993 and for securities at January 1, 1994, as
described in  Notes  11  and  1, respectively,  to  the  consolidated  financial
statements.
 
We conducted our audit in accordance with generally accepted auditing standards.
Those  standards require that we plan and perform the audit to obtain reasonable
assurance  about  whether  the  financial   statements  are  free  of   material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
In  our opinion,  the 1995 consolidated  financial statements  referred to above
present fairly, in all  material respects, the  financial position of  Financial
Security  Corp. at December  31, 1995, and  the results of  their operations and
their cash flows for the year  then ended in conformity with generally  accepted
accounting principles.

obtain  reasonable assurance about whether the  financial statements are free of
material misstatement. An audit  includes examining, on  a test basis,  evidence
supporting  the amounts  and disclosures in  the financial  statements. An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well  as  evaluating the  overall  financial  statement
presentation.  We believe  that our  audits provide  a reasonable  basis for our

                             INTRODUCTORY STATEMENT
 
    WHEREAS, the  Boards of  Directors  of the  Purchaser  and the  Seller  have

    WHEREAS,   the   Purchaser   and   the  Seller   desire   to   make  certain

which shall be as follows:
 
                                   ARTICLE I
                                   THE MERGER
 
    SECTION 1.01  STRUCTURE OF  THE MERGER.  Upon the  terms and subject to  the
conditions  of  this Agreement,  on the  Effective Date  (as defined  in Section
7.01), Seller shall merge  (the "Merger") with and  into the Purchaser and  such
Merger  is intended to qualify as a tax-free reorganization under Section 368(a)
of the Code; the  separate existence of Seller  shall cease; Purchaser shall  be
the  surviving corporation in the Merger  (the "Surviving Corporation"); and all
property, real,  personal and  mixed, and  all debts  due on  whatever  account,
including  subscriptions to shares, and all other  choses in action, and all and
every other interest, of or belonging to or due to each of Purchaser and Seller,
shall be taken  and deemed  to be  transferred to  and vested  in the  Surviving
Corporation  without further act or  deed; and the title  to any real estate, or
any interest therein, vested in any of such corporations shall not revert or  be
in  any  way  impaired by  reason  of the  Merger;  all in  accordance  with the
applicable laws of the State  of Illinois or any  other applicable laws. At  the

Effective  Time shall cease  to be outstanding, shall  be deemed surrendered and
each such share shall be converted into  and become the right to receive one  of

<PAGE>
       (iii)
           the right to  receive an  amount in  cash equal  to 30%  of the  Cash

           Exchange  Ratio, (the "Combined  Distribution(s)") subject to Section
           1.02(c);
 
as the holder  thereof shall  elect or  be deemed  to have  elected pursuant  to
Section  1.03 of  this Agreement (the  aggregate of the  Cash Distributions, the
Stock Distributions  and  the  Combined Distributions  payable  and/or  issuable
pursuant  to  this  Agreement at  the  Effective Time  is  sometimes hereinafter
collectively referred to as the "Merger Consideration").
 
    Shares of Seller Common Stock  held by Seller or  any of it Subsidiaries  as
defined  in Section 2.01(a)(ii) of this Agreement, or by Purchaser or any of its

shall  be  converted pursuant  to  this Section  1.02  but shall  be  treated in
accordance with the procedures set forth in Section 1.05 of this Agreement.
 
    (c) Notwithstanding Section 1.02(b)(ii) and (iii) above,
 
       (i) if the Purchaser Average  Stock Price (as  defined below) is  greater
           than  $35.00 per share, then on the business day prior to the Closing
    Date, the Exchange Ratio shall be adjusted such that the stock consideration
    shall equal $31.00 divided  by the Purchaser  Average Stock Price,  provided
    that,  if the  Purchaser Average Stock  Price exceeds $37.00  per share, the
    Exchange Ratio  shall  be .8378  and  Purchaser  shall have  the  option  of
    terminating  this Agreement  pursuant to  Section 6.01(f)  hereof; PROVIDED,
    HOWEVER, that  Purchaser shall  not  have an  option to  terminate  pursuant
    hereto if not later than two business days prior to the Closing Date, Seller

    by the Purchaser Average Stock Price; or
 
       (ii)if  the Purchaser Average Stock Price  is less than $30.00 per share,
           then on the  business day  prior to  the Closing  Date, the  Exchange
    Ratio shall be adjusted such that the stock consideration shall equal $26.00
    divided  by  the  Purchaser  Average  Stock  Price,  provided  that,  if the
    Purchaser Average Stock Price  is less than $28.00  per share, the  Exchange
    Ratio  shall be .9286 and  Seller shall have the  option of terminating this
    Agreement pursuant to Section 6.01(g) hereof; PROVIDED, HOWEVER, that Seller
    shall not have an option to terminate pursuant hereto if not later than  two
    business  days prior to the Closing Date  Purchaser has agreed to modify the
    Exchange Ratio to be the quotient of $26.00 divided by the Purchaser Average
    Stock Price.
 
    (d) The "Purchaser  Average Stock Price"  means the average  of the  closing
prices  per share of Purchaser Common Stock reported by the National Association
of Securities Dealers, Inc. ("NASD") on the  ten (10) trading days on which  one
or  more trades  actually occurs  immediately prior  to the  second business day
preceding the Closing Date.
 
    SECTION 1.03 CONVERSION ELECTION PROCEDURES.
 
    (a) Concurrently  with the  mailing to  the shareholders  of Seller  of  the
"Proxy  Statement" (as defined in Section 2.01(bb) of this Agreement), including
the prospectus contained  in the  "Registration Statement" (also  as defined  in
Section  2.01(bb) of this Agreement)  and at least thirty-five  days prior to an
anticipated Effective Date or on such date as mutually agreed upon by  Purchaser
and  Seller,  Purchaser shall  cause the  "Exchange Agent"  (as defined  in this
Section 1.03(a) below) to mail to each holder of record of Seller Common Stock a
form of election in such form as  Purchaser and Seller shall mutually agree  (an
"Election Form") on which such holder shall make the election as provided for in
Section  1.03(b) of this  Agreement. Purchaser shall cause  an Election Form and
other appropriate and customary materials for the purpose of making the election
provided for in Section 1.03(b) of this  Agreement to be sent to each holder  of
Seller  Common Stock who Seller advises Purchaser  has become a holder of Seller
Common Stock after the record date of the special meeting of shareholders called
to vote upon  this Agreement  and the  Merger. Seller  shall have  the right  to
review  both  the  Election  Form  and  other  election  materials  and  provide
reasonable comments thereon.
 
                                      I-2
<PAGE>
"Exchange Agent" shall mean Harris Trust and Savings Bank, or such other bank or
trust  company  or  affiliate  thereof  selected  by  Purchaser  and  reasonably
acceptable   to  Seller  to   effect  the  exchange   of  certificates  formerly
representing shares of Seller Common  Stock (each a "Certificate,"  collectively
"Certificates") for the Merger Consideration.
 
    (b)  Each Election Form shall  specify the type(s) and  amounts of each such
type of Merger Consideration receivable by the holder of Seller Common Stock  in
the  Cash Distribution, the Stock Distribution and the Combined Distribution and
shall permit each such holder to elect  to receive, as provided in Section  1.02
of  this  Agreement, (i)  the Cash  Distribution (in  which case,  such holder's
shares of Seller Common  Stock shall be  deemed to be and  shall be referred  to
herein  as "Cash Election Shares"), (ii)  the Stock Distribution (in which case,
such holder's shares of Seller Common Stock  shall be deemed to be and shall  be
referred   to  herein  as  "Stock  Election  Shares"),  or  (iii)  the  Combined
Distribution (in which case, such holder's  shares of Seller Common Stock  shall
be deemed to be and shall be referred to herein as "Combined Election Shares").
 
    (c)   Any  shares of Seller  Common Stock  with respect to  which the holder
thereof shall not,  as of the  "Election Deadline" (as  defined in this  Section
1.03(c)  below), have made an election  to receive either the Cash Distribution,
the Stock Distribution or the Combined Distribution (such holder's shares  being
deemed  to  be and  shall  be referred  to herein  as  "No Election  Shares") by
submission to the Exchange  Agent of an  effective, properly completed  Election
Form shall be deemed to be Stock Election Shares. "Election Deadline" shall mean
5:00  p.m., local time, on the  day prior to the date  of the special meeting of
shareholders of Seller called to vote upon this Agreement and the Merger or such
other date mutually agreed to by the Seller and Purchaser.
 
    (d)   For purposes  of Section  1.03(f) of  this Agreement,  any  Dissenting
Shares  shall be deemed to be Cash Election Shares; PROVIDED, HOWEVER, that such
Dissenting Shares shall in all cases be payable in cash and shall not be subject
to pro  rata  reduction,  if  required, of  the  Cash  Distribution  payable  in
conversion  of the other Cash Election Shares as set forth in Section 1.03(f) of
this Agreement. In addition, for purposes of Section 1.03(f) of this  Agreement,
the  number of shares ("Seller  Stock Options") of Seller  Common Stock that are
issuable upon the exercise of any stock options granted by Seller and  disclosed
to  Purchaser in writing shall  be exchanged pursuant to  Section 4.03 and shall
not be  subject to  any  pro rata  reduction  under Section  1.03(f);  PROVIDED,
HOWEVER,  that such  Seller Stock  Options shall in  all cases  be payable, upon
exercise in accordance with the terms  of the plan and/or agreement under  which
they were issued and/or evidenced, in shares of Purchaser Common Stock.
 
    (e)  Any election for purposes of Section 1.03(b) of this Agreement shall be
effective  only if the Exchange Agent shall have received the properly completed
Election Form by  the Election  Deadline. Any Election  Form may  be revoked  or
changed  by the person submitting such Election Form or any other person to whom
the  shares  that  are  the  subject  of  the  Election  Form  are  subsequently
transferred.  Such revocation or  change shall be effected  by written notice by
such person  to the  Exchange Agent  PROVIDED  such notice  is received  by  the
Exchange Agent at or prior to the Election Deadline. All Election Forms shall be
deemed  to be  revoked if the  Exchange Agent  is notified in  writing by either
Purchaser or Seller that this Agreement  has been terminated in accordance  with
its terms (with a copy of such writing to be provided to Purchaser or Seller, as
appropriate).  The Exchange Agent shall  have reasonable discretion to determine
when any election, modification  or revocation is received  or whether any  such
election,  modification or revocation is effective,  consistent with the duty of
the  Exchange  Agent  to  give  effect  to  such  elections,  modifications   or
revocations to the maximum extent possible.
 
    (f)   As  soon as practicable  after the Election  Deadline, Purchaser shall
cause the Exchange Agent  to allocate among the  holders of Seller Common  Stock
the right to receive the Cash Distribution, as follows:
 
        If  the total number of shares of Purchaser Common Stock issuable to all
    holders  of  Stock   Election  Shares  and   Combined  Election  Shares   is
    insufficient in the reasonable judgment of Muldoon Murphy & Faucette ("MMF")
    to   allow   it   to   render  the   opinion   required   by   Section  4.14
 
                                      I-3
<PAGE>
    of this  Agreement, then,  MMF shall  notify the  Exchange Agent  as to  the
    number  of additional shares of Purchaser Common Stock that will be required
    to be issued in the Merger in order  to allow MMF to render such opinion  in
    its reasonable judgment (the "Minimum Share Notice"); PROVIDED, HOWEVER, the
    aggregate  Merger Consideration (calculated using the Exchange Ratio and the
    Purchaser Average Stock Price)  so determined consists of  at a minimum  55%
    stock  consideration (or such higher  percentage of stock consideration that
    MMF considers necessary to qualify the  Merger as a tax free  reorganization
    within the meaning of Section 368(a) of the Code).
 
        Upon  receipt  of the  Minimum Share  Notice,  the Exchange  Agent shall
    reallocate the Merger Consideration payable to each holder of Cash  Election
    Shares pro rata (based upon the number of Cash Election Shares owned by such
    holder  as compared with the  total number of Cash  Election Shares owned by
    all holders) such that the holders of Cash Election Shares will receive  the
    number of shares of Purchaser Common Stock which in the aggregate will equal
    the  number of  shares of  Purchaser Common Stock  set forth  in the Minimum
    Share Notice to the Exchange Agent and such holders will receive the balance
    of the Merger Consideration, if any,  to which each such holder is  entitled
    to  receive pursuant to the Merger (determined by (x) computing the value of
    the Merger Consideration to  which each such holder  is entitled to  receive
    pursuant  to the Merger by multiplying the number of shares of Seller Common
    Stock owned at  the Effective  Time by  the per  share value  of the  Merger
    Consideration  and (y) subtracting  from the amount  determined in (x) above
    the value of the  shares of Purchaser Common  Stock issued pursuant to  this
    Section 1.03(f)) in cash.
 
    (g)    The  computation  of  the  pro  rata  computations  utilized  in  the
reallocations  and  the  reallocated   payments  of  the  Merger   Consideration
contemplated  by Section 1.03(f) of this Agreement shall be made by the Exchange
Agent in the reasonable exercise of its discretion.
 
    (h)   Each separate  entry on  the Seller's  Shareholder List  (as  provided
pursuant  to Section 1.07 hereof) shall be  presumed to represent a separate and
distinct holder of record  of Seller Common  Stock. Shares held  of record by  a
bank,  trust company, broker, dealer or other recognized nominee shall be deemed
to be held  by a single  holder unless  the nominee advises  the Exchange  Agent
otherwise  in writing.  In such  case, each  of the  beneficial owners  shall be
treated as a  separate holder and  either directly or  through such nominee  may
submit  a separate  Election Form  for shares  of Seller  Common Stock  that are
beneficially owned.
 
    (i)  Any provisions of the preceding paragraphs of this Section 1.03 to  the
contrary  notwithstanding, if  a holder  of Seller Common  Stock in  two or more
different names so certifies in writing on or before the Election Deadline, such
shareholder may submit a single Election Form for all such shares subject to the
certification and shall be treated for purposes of this Section 1.03 as a single
holder.
 
    SECTION 1.04 EXCHANGE PROCEDURES.
 
    (a)  At the Effective Time, Purchaser shall have granted the Exchange  Agent
the  requisite power and authority  to effect for Purchaser  the issuance of the
number of shares of Purchaser  Common Stock to be issued  in the Merger and  the
payment  of  the  amount  of cash  to  be  paid in  the  Merger.  Promptly after
consummation of  the Merger,  Purchaser  shall deposit,  or  shall cause  to  be
deposited,  with the Exchange Agent, for the benefit of the holders of shares of
Seller Common Stock for exchange in accordance with this Article I, through  the
Exchange  Agent, (i) certificates evidencing such  number of shares of Purchaser
Common Stock equal to the number of shares to be issued pursuant to Section 1.02
and (ii) cash in the amount equal to the aggregate amount of cash to be paid  to
shareholders pursuant to Section 1.02 (such certificates for shares of Purchaser
Common  Stock, together with any dividends or distributions with respect thereto
and cash, being hereinafter  referred to as the  "Exchange Fund"). The  Exchange
Agent  shall, pursuant to irrevocable instructions, deliver the Purchaser Common
Stock and cash contemplated  to be issued  pursuant to Section  1.02 out of  the
Exchange  Fund. Except as contemplated by Section 1.06 hereof, the Exchange Fund
shall not be used for any other purpose.
 
                                      I-4
<PAGE>
    (b)  As soon as  practicable following the Effective  Time, but in no  event
later  than  ten (10)  days thereafter,  the  Exchange Agent  shall mail  to the
holders of record of  a Certificate or Certificates  of Seller Common Stock,  as
identified  on the  Seller Shareholder  List provided  pursuant to  Section 1.07
hereof, (1) a letter of transmittal (which shall specify that delivery shall  be
effected,  and risk of loss  and title to the  Certificate shall pass, only upon
proper delivery of the Certificates to the  Exchange Agent and shall be in  such
form and have such other provisions as Purchaser and Seller shall mutually agree
upon)   and  (2)  instructions  for  use  in  effecting  the  surrender  of  the
Certificates in exchange for Certificates evidencing shares of Purchaser  Common
Stock  or  cash.  Seller shall  have  the right  to  review both  the  letter of
transmittal and any other transmittal materials prior to the Effective Time  and
provide  reasonable comments  thereon. Upon  surrender of  a Certificate  to the
Exchange Agent together with such letter of transmittal, duly executed, and such
other customary documents  in proper form  as may be  required pursuant to  such
instructions,  the holder of  such Certificates shall be  entitled to receive in
exchange therefor (A)  certificates evidencing  that number of  whole shares  of
Purchaser  Common Stock which such holder has the right to receive in respect of
the shares of  Seller Common Stock  formerly evidenced by  such Certificate,  in
accordance  with Section  1.02, (B)  cash to  which such  holder is  entitled to
receive in accordance with Section 1.02,  (C) cash in lieu of fractional  shares
of  Purchaser Common Stock to which such  holder is entitled pursuant to Section
1.06 and  (D) any  dividends or  other  distributions to  which such  holder  is
entitled  pursuant to Section 1.04, and  the Certificate so surrendered shall be
cancelled.
 
    (c)  Subject to Section 1.07  hereof, after the Effective Time, each  holder
of  a  Certificate that  surrenders  such Certificate  or  in lieu  thereof, any
reasonable documentation  required  by the  Purchaser  for a  lost,  stolen,  or
mutilated Certificate (the "Required Documentation") to the Exchange Agent, with
a  properly completed  and executed letter  of transmittal with  respect to such
Certificate, will be entitled to a certificate or certificates representing  the
stock  component of the  Merger Consideration and/or  a payment representing the
cash component of the Merger Consideration.
 
    (d)  Each outstanding  Certificate, until duly  surrendered to the  Exchange
Agent,  shall be deemed  to evidence ownership of  the Merger Consideration into
which the  stock previously  represented  by such  Certificate shall  have  been
converted pursuant to this Agreement.
 
    (e)   After the Effective Time, holders  of Certificates shall cease to have
rights with respect to  the stock previously  represented by such  Certificates,
and  their sole  rights shall  be to exchange  such Certificates  for the Merger
Consideration issuable  or payable  in  the Merger.  After  the closing  of  the
transfer  books as described in  Section 1.07 hereof, there  shall be no further
transfer on the records of Seller of Certificates, and if such Certificates  are
presented  to Seller for  transfer, they shall be  cancelled against delivery of
the Merger  Consideration. Neither  Purchaser nor  the Exchange  Agent shall  be
obligated  to deliver  the Merger  Consideration to  which any  former holder of
Seller Common Stock  is entitled as  a result  of the Merger  until such  holder
surrenders the Certificates or the Required Documentation as provided herein. No
interest  will  be  accrued  or  paid  on  the  cash  component  of  the  Merger
Consideration. No dividends or distributions  declared after the Effective  Time
on  the Purchaser  Common Stock representing  the stock component  of the Merger
Consideration will be  remitted to  any person  entitled to  receive such  stock
component  of the  Merger Consideration under  this Agreement  until such person
surrenders the  Certificate representing  the right  to receive  such  Purchaser
Common  Stock  or  furnishes  the Required  Documentation,  at  which  time such
dividends or declarations shall be remitted to such person, without interest and
less any taxes that  may have been imposed  thereon. Neither the Exchange  Agent
nor any party to this Agreement nor any affiliate thereof shall be liable to any
holder  of stock  represented by  any Certificate  for any  Merger Consideration
issuable or payable in the Merger that is paid to a public official pursuant  to
applicable  abandoned property, escheat or similar  laws without interest on the
cash component, but with  accrued but unpaid dividends  on the Purchaser  Common
Stock.
 
    (f)  Any portion of the Exchange Fund which remains undistributed to holders
of  Seller Common Stock for eighteen (18)  months after the Effective Time shall
be delivered to Purchaser,  upon demand and any  holders of Seller Common  Stock
who    have   not   theretofore    complied   with   this    Article   I   shall
 
                                      I-5
<PAGE>
thereafter look only to Purchaser for the Merger Consideration to which they are
entitled without interest  on the cash  component, but with  accrued and  unpaid
dividends on the Purchaser Common Stock.
 
    SECTION 1.05  DISSENTING SHARES.
 
    (a)   Notwithstanding any other provision of this Agreement to the contrary,
any  holder  of  Seller  Common  Stock  otherwise  entitled  to  receive  Merger
Consideration  for each of his or her shares shall be entitled to demand payment
of the  fair cash  value of  such  shares as  specified in  Section 262  of  the
Delaware  General Corporation Law  ("DGCL") if the  holder follows the procedure
specified therein.  These shares  shall hereafter  be specified  as  "Dissenting
Shares."  Any holders of Dissenting Shares shall be entitled to payment for such
shares only to the extent permitted by and in accordance with the provisions  of
such  law,  and Purchaser  shall  cause the  surviving  corporation to  pay such
consideration with funds provided by  the Purchaser. Any Dissenting Share  shall
not,  after the Effective Time,  be entitled to vote  for any purpose or receive
any dividends or other distributions and shall not be converted into the  Merger
Consideration as provided in Section 1.02 hereof; PROVIDED, HOWEVER, that shares
of  Seller  Common  Stock  held by  a  dissenting  stockholder  who subsequently
withdraws a demand for payment, fails  to comply fully with the requirements  of
the  DGCL, or otherwise fails  to establish the right  to such stockholder to be
paid for fair cash value  of such stockholder's shares  under the DGCL shall  be
deemed  to be converted  into the right  to receive the  Merger Consideration in
cash pursuant to the terms and conditions specified herein.
 
    (b)  Each party  hereto shall give  the other prompt  notice of any  written
demands  for the payment  of the fair  value of any  shares, withdrawals of such
demands, and any other instruments, served pursuant to the DGCL received by such
party, and Seller  shall give Purchaser  the opportunity to  participate in  all
negotiations  and proceedings  with respect  to such  demands. Seller  shall not
voluntarily make any  payment with respect  to any demands  for payment of  fair
value  and shall not, except with the  prior written consent of Purchaser, which
consent shall not be unreasonably withheld,  settle or offer to settle any  such
demands.
 
    SECTION  1.06  NO FRACTIONAL SHARES.  Notwithstanding any other provision of
this  Agreement,  neither  certificates  nor  scrip  for  fractional  shares  of
Purchaser  Common Stock shall be issued in the Merger. Each holder who otherwise
would have been  entitled to a  fraction of  a share of  Purchaser Common  Stock
shall receive in lieu thereof cash (without interest) in an amount determined by
multiplying  the fractional share interest to  which such holder would otherwise
be entitled  by the  Purchaser Average  Stock  Price. No  such holder  shall  be
entitled  to dividends,  voting rights  or any  other rights  in respect  of any
fractional share.
 
    SECTION 1.07  CLOSING OF STOCK TRANSFER BOOKS.
 
    (a)   The stock  transfer books  of Seller  shall be  closed at  the end  of
business  on the  business day  immediately preceding  the Closing  Date. In the
event of a transfer of ownership of Seller Common Stock which is not  registered
in  the transfer records prior  to the closing of  such record books, the Merger
Consideration issuable or payable with respect to such stock may be delivered to
the transferee, if the  Certificate or Certificates  representing such stock  is
presented  to  the  Exchange  Agent accompanied  by  all  documents  required to
evidence and effect such  transfer and all applicable  stock transfer taxes  are
paid.
 
    (b)   At the Effective Time, Seller  shall provide Purchaser with a complete
and verified list of  registered holders of Seller  Common Stock based upon  its
stock  transfer books as  of the closing  of said transfer  books, including the
names, addresses,  certificate numbers  and taxpayer  identification numbers  of
such  holders (the "Seller Shareholder List").  Purchaser and the Exchange Agent
shall be entitled  to rely  upon the Seller  Shareholder List  to establish  the
identity of those persons entitled to the Merger Consideration specified in this
Agreement, which list shall be conclusive with respect thereto.

<PAGE>
    SECTION  1.08   ANTI-DILUTION  ADJUSTMENTS.   If  between  the date  of this
Agreement and the  Effective Time  a share of  Purchaser Common  Stock shall  be
changed  into  a different  number  of shares  of  Purchaser Common  Stock  or a
different class  of  shares  by reason  of  reclassification,  recapitalization,
split-up,  combination,  exchange  of  shares or  readjustment,  or  if  a stock
dividend thereon shall be declared with  a record date within such period,  then
appropriate  and proportionate  adjustment or  adjustments will  be made  to the
stock component of the Merger Consideration to reflect such split,  combination,
dividend or other distribution.
 
    SECTION  1.09  MODIFICATION OF STRUCTURE.   Notwithstanding any provision of
this Agreement to the contrary, Purchaser  may elect to modify the structure  of
the  transactions  contemplated hereby  so  long as  (i)  there are  no material
adverse federal  or  state  income  tax  consequences  to  the  Seller  and  its
stockholders  or to  holders of  options to  purchase Seller  Common Stock  as a
result of such  modification; (ii) the  consideration to be  paid to holders  of
Seller  Common Stock or Seller Stock Options under this Agreement is not thereby
changed in kind or  reduced in amount because  of such modification; (iii)  such
modification will not be likely to delay materially or jeopardize receipt of any
required  regulatory approvals; and  (iv) opinions as  to these conditions being
met are  supplied to  Seller by  a public  accountant and  law firm,  in a  form
acceptable to Seller but at the sole expense of Purchaser.
 
    SECTION  1.10  TAKING  OF NECESSARY ACTION.   In case at  any time after the
Effective Time any  further action is  necessary or desirable  to carry out  the
purposes  of  this  Agreement and  to  vest  Purchaser with  full  title  to all
properties, assets, rights, approvals, immunities  and franchises of Seller  and
its  Subsidiaries, the officers  and directors of Purchaser  shall take all such
necessary action.
 
                                   ARTICLE II
                         REPRESENTATIONS AND WARRANTIES
 
    SECTION 2.01  REPRESENTATIONS AND WARRANTIES OF THE SELLER.
 
    The Seller  represents  and  warrants  to  the  Purchaser  that,  except  as
specifically disclosed in the schedules of the Seller delivered to the Purchaser
prior  to the execution hereof (and making  specific reference to the Section or
Sections of this Agreement for which an exception is taken) (such schedules,  as
amended  from time to  time in the  manner provided for  in Section 4.09 hereof,
shall hereafter be referred to as the "Disclosure Schedules"):
 
    (a)  ORGANIZATION.
 
       (i) The Seller is a corporation  duly organized, validly existing and  in
           good standing under the laws of the State of Delaware. Except for the
    Seller  Bank  as  defined in  this  Section  2.01(a), Seller  has  no direct
    subsidiaries. The Seller  is duly qualified  to do business  and is in  good
    standing  in Illinois and in each other  jurisdiction in which the nature of
    the business conducted  or the properties  or assets owned  or leased by  it
    makes such qualification necessary, except for such failure to qualify or be
    in  such good  standing which, when  taken together with  all such failures,
    would not have a Material Adverse  Effect as hereinafter defined in  Section
    2.01(h)  on the Seller. The Seller is  a registered savings and loan holding
    company under the Home Owners' Loan Act, as amended ("HOLA"). The Seller has
    the corporate power and authority  (including all federal, state, local  and
    foreign  government  authority)  to  carry  on its  business  as  it  is now
    conducted and to own, lease and operate its properties.
 
       (ii)Security Federal Savings and Loan Association of Chicago (the "Seller
           Bank") is a  federally chartered stock  savings and loan  association
    duly  organized, validly existing and in good standing under the laws of the
    United States. Security Federal Service  Corp. is a wholly owned  subsidiary
    of  Seller Bank and is a corporation duly organized, validly existing and in
    good standing under  the laws  of the State  of Illinois.  (Seller Bank  and
    Security  Federal Service Corp.  are sometimes referred to  herein each as a
    "Subsidiary" and together as the  "Subsidiaries"). Each of the  Subsidiaries
    has  the corporate power and authority to carry on its business as it is now
    conducted and  to  own,  lease  and operate  its  properties,  and  is  duly
    qualified to do business
 
                                      I-7
<PAGE>
    and  is in  good standing in  each jurisdiction  in which the  nature of the
    business conducted or the properties or  assets owned or leased by it  makes
    such  qualification necessary, except where  the absence thereof, would not,
    individually or  in  the  aggregate,  have  a  Material  Adverse  Effect  as
    hereinafter  defined in  Section 2.01(h) on  the Seller.  Each subsidiary of
    Seller Bank,  as  defined in  Section  2.01(a)(ii), is  a  corporation  duly
    organized,  validly  existing and  in good  standing under  the laws  of the
    jurisdiction in which the subsidiary is incorporated. Seller Bank's deposits
    are insured  by  the Savings  Association  Insurance Fund  ("SAIF")  of  the
    Federal  Deposit  Insurance  Corporation  ("FDIC")  to  the  maximum  extent
    permitted by law.
 
       (iii)
           The Disclosure Schedule 2.01(a) sets forth all of the Subsidiaries of
           the Seller and all  entities (whether corporations, partnerships,  or
    similar organizations), including the corresponding percentage ownership, in
    which  the Seller  owns, directly  or indirectly, 10%  or more  of the debt,
    equity or other proprietary interests as  of the date of this Agreement  and
    indicates  for  each  such entity,  as  of  such date,  its  jurisdiction of
    organization. The Seller  owns, either  directly or indirectly,  all of  the
    outstanding  capital stock of each of the Subsidiaries free and clear of any
    claim, lien or  encumbrance. Except for  Seller Bank, no  Subsidiary of  the
    Seller  is an  "insured depository  institution" as  defined in  the Federal
    Deposit Insurance Act,  as amended, and  applicable regulations  thereunder.
    All  of the shares of capital stock of  each of the Subsidiaries held by the
    Seller or by another Subsidiary of the Seller are fully paid,  nonassessable
    and  not subject to  any preemptive rights  and, except as  set forth in the
    Disclosure Schedule 2.01(a), are owned by the Seller or a Subsidiary of  the
    Seller  free and  clear of any  claims, liens,  encumbrances or restrictions
    (other than those imposed by  applicable federal and state securities  laws)
    and  there are no agreements or understandings with respect to the voting or
    disposition of any such shares so held.
 
    (b)  CAPITAL STRUCTURE.
 
       (i) The authorized capital stock of the Seller consists of  three-million
           (3,000,000)  shares of Seller Common Stock,  par value $.01 per share
    (the "Seller Common Stock") and one million (1,000,000) shares of  preferred
    stock,  par value $.01 per  share (the "Seller Preferred  Stock"). As of the
    date hereof: (A)  1,550,846 shares of  Seller Common Stock  were issued  and
    outstanding  (which  includes outstanding  share  awards under  the Security
    Federal  Savings  and  Loan  Association  Recognition  and  Retention  Plans
    ("ARP"),  and the  Financial Security Corp.  1995 Long  Term Incentive Plan)
    (the "Incentive Plan"), and no shares of Seller Preferred Stock were  issued
    or  outstanding; (B) 103,531  shares of Seller Common  Stock were subject to
    outstanding stock option  awards; (C)  no shares of  Seller Preferred  Stock
    were  reserved for issuance; (D) 246,082  shares of Seller Common Stock were
    held by the  Seller in  its treasury (which  are not  included in  aforesaid
    shares  which are issued  and outstanding), and (E)  58,941 share awards and
    84,699 options  in the  Incentive Plan  were authorized  but have  not  been
    granted.  All outstanding shares of Seller  Common Stock are validly issued,
    fully paid and nonassessable and not  subject to any preemptive rights.  The
    Disclosure  Schedule 2.01(b) sets forth a  complete and accurate list of all
    options, warrants, calls,  or commitments  or other  agreements to  purchase
    Seller  Common  Stock outstanding,  including the  dates of  grant, exercise
    prices, dates of vesting, dates of termination and shares subject to  option
    for each grant.
 
       (ii)As  of the date of  this Agreement, except for  this Agreement and as
           set forth in the Disclosure Schedule 2.01(b), neither the Seller  nor
    any  of  its Subsidiaries  is  a party  to or  is  bound by  any outstanding
    subscriptions, options,  warrants,  calls, rights,  convertible  securities,
    commitments  or agreements of any character  obligating the Seller or any of
    its Subsidiaries to issue, deliver or sell, or cause to be issued, delivered
    or sold, any additional shares of capital stock of the Seller or any of  its
    Subsidiaries  or obligating the Seller or  any of its Subsidiaries to grant,
    extend or  enter into  any such  option, warrant,  call, right,  convertible
    security,  commitment  or agreement.  As of  the date  hereof, there  are no
    outstanding contractual obligations of the Seller or any of its Subsidiaries
    to repurchase, redeem or  otherwise acquire any shares  of capital stock  of
    the Seller or any of its Subsidiaries.
 
                                      I-8

    (c)   AUTHORITY.  The Seller has all requisite corporate power and authority
to enter into this Agreement and, subject  to approval of this Agreement by  the
requisite  vote of the shareholders of the Seller and approval of regulators, to
consummate the transactions contemplated hereby.  The execution and delivery  of
this  Agreement, and, subject to the approval of this Agreement by the requisite
vote of  the  shareholders  of  the  Seller  and  approval  of  regulators,  the
consummation  of the transactions contemplated  hereby have been duly authorized
by all necessary corporate action on the part of the Seller. This Agreement  has
been  duly executed and delivered by the  Seller and, assuming due execution and
delivery by the  Purchaser constitutes  a valid  and binding  obligation of  the
Seller,   enforceable  in  accordance  with  its  terms  subject  to  applicable
conservatorship, receivership, bankruptcy, insolvency and similar laws affecting
creditors' rights and remedies generally, and subject, as to enforceability,  to
general   principles   of   equity   (including   without   limitation  specific
performance), whether applied in a court of law or a court of equity.
 
    (d)   SHAREHOLDER APPROVALS.   The  Board  of Directors  of the  Seller  has
directed  that  this  Agreement  and  the  transactions  contemplated  hereby be
submitted to  the  Seller's shareholders  for  approval  at a  meeting  of  such
shareholders and, except for adoption of this Agreement by the requisite vote of
the  Seller's shareholders, no other shareholder  action is necessary to approve
this Agreement and to consummate the transactions contemplated hereby. The Board
of Directors  will  recommend  that the  shareholders  approve  the  transaction
subject  to their fiduciary duties and  will exempt the transaction from Section
203 of DGCL. The approval  of the majority of  the outstanding shares of  Seller
Common  Stock entitled to vote is required for approval of this Agreement and to
consummate the transactions contemplated hereby.  The Board of Directors of  the
Seller  has received the opinion of Hovde Financial, Inc. to the effect that the
Merger Consideration to be received by  the shareholders of the Seller is  fair,
from a financial point of view, to such shareholders.
 
    (e)   NO VIOLATIONS.  Subject to  approval of this Agreement by the Seller's
shareholders and the regulatory agencies referred to in Section 2.01(g)(ii), the
execution, delivery and performance of this Agreement by the Seller do not,  and
the consummation of the transactions contemplated hereby by the Seller will not,
constitute  (i) a breach or  violation of, or a default  under, any law, rule or
regulation or any judgment,  decree, order, governmental  permit or license,  or
agreement, indenture or instrument of the Seller or any Subsidiary of the Seller
or  to which the Seller  or any of its Subsidiaries  (or any of their respective
properties) is subject, which breach,  violation or default would,  individually
or  in the aggregate, have  a Material Adverse Effect  as hereinafter defined in
Section 2.01(h) on Seller or on Seller's ability to consummate the  transactions
contemplated  hereby, (ii)  a breach  or violation of,  or a  default under, the
certificate or  articles  of  incorporation  or Bylaws  of  the  Seller  or  any
Subsidiary  of the Seller or (iii) a breach  or violation of, or a default under
(or an event which with due notice or  lapse of time or both would constitute  a
default  under), or  result in  the termination  of, accelerate  the performance
required by, or result in the  creation of any lien, pledge, security  interest,
charge  or other encumbrance upon any of  the properties or assets of the Seller
or any  Subsidiary  of  the  Seller  under, any  of  the  terms,  conditions  or
provisions  of any note, bond, indenture, deed of trust, loan agreement or other
agreement, instrument or obligation to which the Seller or any Subsidiary of the
Seller is a party, or to which any of their respective properties or assets  may
be  bound or affected, except for any  of the foregoing that, individually or in
the aggregate, would not have a Material Adverse Effect on the Seller.
 
    (f)   CONSENTS.   Except  as referred  to herein  or  in connection,  or  in
compliance,  with the Securities Act of 1933, as amended (the "Securities Act"),
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the  HOLA,
the  Bank Merger Act, as  amended (the "BMA"), the  rules and regulations of the
Federal Reserve  Board,  the rules  and  regulations  of the  Office  of  Thrift
Supervision  ("OTS"), and the environmental, corporation, securities or blue sky
laws or regulations of  the various states, no  filing or registration with,  or
authorization, consent or approval of, any public body or authority is necessary
for  the consummation  by the  Seller of  the Merger  or the  other transactions
contemplated   by   this   Agreement,   other   than   filings,   registrations,
authorizations,  consents or approvals  the failure to make  or obtain would not
have a Material Adverse Effect on the Seller.

<PAGE>
    (g)  REPORTS.
 
       (i) As of their respective dates,  neither the Seller's Annual Report  on
           Form  10-KSB for  the fiscal  year ended  December 31,  1995, nor any
    other document filed subsequent  to December 31,  1995 under Section  13(a),
    13(c),  14 or  15(d) of the  Exchange Act,  each in the  form (including any
    documents specifically  incorporated by  reference therein)  filed with  the
    Securities  and  Exchange  Commission ("SEC")  (collectively,  the "Seller's
    Reports"), contained or will contain any untrue statement of a material fact
    or omitted or  will omit  to state  a material  fact required  to be  stated
    therein  or necessary to make  the statements made therein,  in light of the
    circumstances under which they were made, not misleading, PROVIDED, HOWEVER,
    that no representation is  made herein with respect  to any Exhibits to  the
    Seller's Reports that are not specifically incorporated by reference therein
    and  that Seller's amendment  of any Seller's  Report, in and  of itself, in
    response to SEC comments will not be violative of this section. Each of  the
    balance  sheets of the Seller or  its Subsidiaries contained or specifically
    incorporated by reference in  the Seller's Reports  (including in each  case
    any  related notes and schedules) fairly presented the financial position of
    the entity or entities to  which it relates as of  its date and each of  the
    statements  of income  and of  changes in  shareholders' equity  and of cash
    flows  of  the  Seller  or  its  Subsidiaries,  contained  or   specifically
    incorporated  by reference in  the Seller's Reports  (including in each case
    any related notes and schedules) (collectively the "Financial  Statements"),
    fairly  presented the results  of operations, shareholders'  equity and cash
    flows, as the case may be, of the entity or entities to which it relates for
    the periods set  forth therein (subject,  in the case  of unaudited  interim
    statements,   to  normal  year-end  audit  adjustments),  in  each  case  in
    accordance  with   generally   accepted   accounting   principles   ("GAAP")
    consistently  applied during  the periods involved,  except as  may be noted
    therein.
 
       (ii)The Seller and each of its Subsidiaries have each filed all  material
           reports,  registrations and statements,  together with any amendments
    required to be made  with respect thereto, that  they were required to  file
    since December 31, 1995 with (A) the SEC, (B) the OTS, (C) the FDIC, (D) any
    state   banking   commission   or   other   banking   regulatory   authority
    (collectively, the "Regulatory Agencies")  and (E) the National  Association
    of  Securities  Dealers,  Inc. and  any  other  self-regulatory organization
    ("SRO"), and  have  paid  all  fees  and  assessments  due  and  payable  in
    connection  therewith, except for those fees  and assessments that would not
    be material.
 
    (h)  ABSENCE  OF CERTAIN  CHANGES OR  EVENTS.   Except as  disclosed in  the
Seller's  Reports filed prior to  the date of this  Agreement, (i) from December
31, 1995 to the date hereof, the Seller and its Subsidiaries have not, except as
set forth in the Disclosure  Schedule 2.01(h), incurred any material  liability,
other  than  in  the ordinary  course  of  their business  consistent  with past
practice, and (ii) since  December 31, 1995, there  has not been any  condition,
event,  change or occurrence that, individually or in the aggregate, has had, or
is reasonably likely  to have,  a Material  Adverse Effect  on the  Seller or  a
Subsidiary.  Material Adverse Effect, with respect to a person, means a material
adverse effect upon (A) the business, properties, assets, financial condition or
results of  operations, in  each case,  of  the Seller  or its  Subsidiaries  or
Purchaser  or its subsidiaries, as appropriate either individually or taken as a
whole, or  (B)  the  ability  of such  person  to  consummate  the  transactions
contemplated  by this  Agreement; it  being understood  that a  Material Adverse
Effect shall not include: (i) a change with respect to, or effect on, the Seller
and its Subsidiaries resulting from a change in law, rule, regulation, generally
accepted accounting principles  or regulatory  accounting principles,  including
any  change in  the treatment of  bad debt reserves  as such would  apply to the
financial statements of the Seller on  a consolidated basis; (ii) a change  with
respect  to,  or  effect on,  the  Seller  and its  Subsidiaries  resulting from
expenses (such as legal,  accounting and investment  bankers' fees) incurred  in
connection  with this Agreement or the transactions contemplated hereby; (iii) a
change with respect to, or effect  on, the Seller or its Subsidiaries  resulting
from  any other  matter affecting  depository institutions  generally including,
without limitation,  changes  in  general economic  conditions  and  changes  in
prevailing  interest and deposit  rates; or (iv)  any one-time special insurance
premium assessed by the FDIC on deposits insured by the SAIF.

<PAGE>
    (i)  TAXES.  All federal, state, and local tax returns required to be  filed
by  or on behalf of the Seller or any of its Subsidiaries have been timely filed
or requests for extensions have been timely filed (and any such extension  shall
have been granted and not have expired). All taxes, owed by Seller or any of its
Subsidiaries  (whether or not shown on the returns) and all taxes required to be
shown on returns for which extensions have been granted, have been paid in  full
or  adequate provision has been made for  any such taxes on the Seller's balance
sheet as of  December 31,  1995 (in accordance  with GAAP).  Since December  31,
1995,  there has been no audit examination of the Seller by the Internal Revenue
Service ("IRS) and the latest audit examination of the Seller by the  applicable
taxing authority of the State of Illinois was October 26, 1995 for the tax years
ended  1990, 1991,  1992 and  1993. Except as  set forth  in Disclosure Schedule
2.01(i), as  of the  date of  this  Agreement, there  is no  audit  examination,
deficiency,  claim, or refund litigation with respect to any taxes of the Seller
or any of  its Subsidiaries, and  no claim or  assessment has been  made by  any
authority  in a jurisdiction where the Seller  or any of its Subsidiaries do not
file tax returns and the Seller or  any such Subsidiary is subject to  taxation.
All  taxes, interest, additions, and penalties due with respect to completed and
settled examinations or concluded  litigation relating to the  Seller or any  of

    or any of its Subsidiaries is or has been a party or subject with respect to
    any  present or former directors, officers, or other employees of the Seller
    or any  of its  Subsidiaries (hereinafter  referred to  collectively as  the
    "Employee  Plans"),  except for  any  such plans,  contracts,  agreements or
    arrangements  involving  liabilities  or  expenses  not  exceeding   $10,000
    individually  or in the aggregate.  All of the Employee  Plans comply in all
    material respects with all  applicable requirements of  ERISA, the Code  and
    other applicable laws, orders, rules and regulations; neither the Seller nor
    any  of  its  Subsidiaries has  engaged  in a  "prohibited  transaction" (as
 
                                      I-12
<PAGE>
    defined in Section 406 of ERISA or Section 4975 of the Code) with respect to
    any Employee Plan. Seller and its Subsidiaries have complied with the health
    care continuation coverage  requirements of  Section 4980B of  the Code  and
    Sections  601  through 608  of ERISA.  No liability  to the  Pension Benefit
    Guaranty  Corporation  has  been  incurred  and,  except  as  described   on
    Disclosure  Schedule  2.01(n), there  exists no  fact or  circumstance which
    would cause  the Seller  to incur  any such  liability with  respect to  any
    Employee  Plan which is  subject to Title  IV of ERISA  ("Pension Plan"), or
    with  respect  to  any  "single-employer   plan"  (as  defined  in   Section
    4001(a)(15)  of ERISA) currently or formerly maintained by the Seller or any
    entity which is considered one employer  with the Seller under Section  4001
    of  ERISA  or Section  414 of  the  Code (an  "ERISA Affiliate").  Except as

    (whether or not waived)  as of the last  day of the end  of the most  recent
    plan year ending prior to the date hereof; the present value of the "benefit
    liabilities" (as defined in Section 4001(a)(16) of ERISA) under each Pension
    Plan  as  of the  date  hereof, calculated  on  the basis  of  the actuarial
    assumptions used in  the most  recent actuarial valuation  for such  Pension
    Plan  as of  the date hereof  does not exceed  the fair market  value of the
    assets of  such Pension  Plan, and  no notice  of a  "reportable event"  (as
    defined in Section 4043 of ERISA) for which the 30-day reporting requirement
    has  not been  waived has  been required  to be  filed for  any Pension Plan
    within the 12-month period ending on the date hereof. Neither the Seller nor
    any Subsidiary  of the  Seller  has provided,  or  is required  to  provide,
    security  to any  Pension Plan  or to any  single-employer plan  of an ERISA
    Affiliate pursuant to Section  401(a)(29) of the  Code. Neither the  Seller,
    its  Subsidiaries, nor any  ERISA Affiliate currently  contributes or, since
    December 31, 1988, has contributed to any multiemployer plan, as defined  in
    Section  3(37) of ERISA. Except as disclosed on Disclosure Schedule 2.01(n),
    each Employee Plan of the Seller or  of any of its Subsidiaries which is  an
    employee  "pension benefit plan"  (as defined in Section  3(2) of ERISA) and
    which is  intended to  be qualified  under  Section 401(a)  of the  Code  (a
    "Qualified Plan") has received a favorable determination letter from the IRS
    that  the pension  benefit plan  meets the  Tax Reform  Act of  1986 and all
    applicable legislative  and regulatory  requirements for  tax  qualification
    that  became effective at the time  that the determination letter was issued
    and the Seller and its Subsidiaries are not aware of any circumstances which
    would result in revocation of any such favorable determination letter.  Each
    Qualified  Plan which is  an "employee stock ownership  plan" (as defined in
    Section 4975(e)(7)  of  the  Code)  has  satisfied  all  of  the  applicable
    requirements  of Sections 409 and 4975(e)(7) of the Code and the regulations
    thereunder in all  material respects and  any assets of  any such  Qualified
    Plan that are not allocated to participants' individual accounts are pledged
    as  security for, and subject  to the provisions of  Section 4.02(e) of this
    Agreement  may   be  applied   to   satisfy,  any   securities   acquisition
    indebtedness.
 
          (ii)
           There  is  no  pending  or,  to  the  Seller's  knowledge, threatened
           litigation, administrative  action  or  proceeding  relating  to  any
    Employee  Plan and  the Seller  has not  received any  notification from any
    federal, state or  local agency  or department asserting  that any  Employee
    Plan  is  not  in  compliance  with  any  of  the  statutes,  regulations or
    ordinances that  such governmental  authority enforces.  There has  been  no
    announcement  or commitment by the Seller or any Subsidiary of the Seller to
    create an additional Employee Plan, or to amend an Employee Plan except  for
    amendments  required by applicable law which  do not materially increase the
    cost of such Employee Plan and except for any plans or amendments  expressly
    described herein or on Disclosure Schedule 2.01(n); and, except as set forth
    in  Disclosure Schedule 2.01(n), the Seller and its Subsidiaries do not have
    any obligations for  post-retirement or post-employment  benefits under  any
    Employee  Plan  (exclusive  of  any coverage  mandated  by  the Consolidated
    Omnibus Reconciliation Act of 1986 ("COBRA").

foreclosure   or  other  transfer  in  satisfaction  of  a  debtor's  obligation
previously contracted),  except  for Liens,  as  defined below,  or  such  other
defects  arising by operation of law or  which would not, individually or in the

duty. Each of the Seller  and its Subsidiaries has good  and valid title to  its
owned  personal property free and clear of all Liens, except for Liens, or other

federal,  state or other public authorities necessary for the conduct of its and
their business as  it is presently  conducted except where  the absence  thereof
would  not, individually or in the aggregate,  have a Material Adverse Effect on
the Seller  or  materially  delay  the  Merger.  Each  of  the  Seller  and  the
Subsidiaries has conducted its business so as to comply in all respects with all
applicable  federal, state and local statutes, ordinances, regulations or rules,

           Except as set forth in Disclosure Schedule 2.01(s), each  outstanding
           loan of Seller Bank as of the date hereof is evidenced by appropriate

interest-bearing assets  of  the Seller  and  its Subsidiaries  that  have  been
classified  as  of  December  31, 1995  as  "Other  Loans  Specially Mentioned,"
"Special   Mention,"    "Substandard,"   "Doubtful,"    "Loss,"    "Classified,"
"Criticized,"  "Credit Risk Assets," "Concerned Loans" (in the latter two cases,
to the extent available)  or words of  similar import. From  and after the  date
hereof,  the Seller  promptly will  provide the  Purchaser with  a copy  of each
monthly classified asset report it provides  to its Board of Directors. The  REO
included  in any non-performing assets of the  Seller or any of its Subsidiaries
is carried net of reserves at the lower of cost or fair value.
 
    (u)   MATERIAL  INTERESTS  OF CERTAIN  PERSONS.    Except as  set  forth  in
Disclosure  Schedule 2.01(u), to  Seller's knowledge, no  officer or director of
the Seller has any material interest in any material contract or property  (real
or  personal), tangible or intangible, used in  or pertaining to the business of
the Seller or any  of its Subsidiaries  that would be  required to be  disclosed
under the SEC's Regulation S-K.
 
    (v)   INSURANCE.  The Seller and its Subsidiaries are presently insured, and
since  December  31,  1995  have  been  insured,  for  reasonable  amounts  with
financially  sound  and reputable  insurance  companies, against  such  risks as
companies engaged in a similar business located in the State of Illinois  would,
in  accordance with good business practice, customarily be insured. All material
claims thereunder have been filed in due and timely fashion. Neither Seller  nor
Seller  Bank has  any knowledge  of any inaccuracy  in any  application for such
policies or binders, any failure to pay  premiums when due or any similar  state
of  facts that  might form  the basis for  termination of  such insurance except
where such failure would not  have a Material Adverse  Effect on Seller and  its
Subsidiaries on a consolidated basis.
 
    (w)   INVESTMENT  SECURITIES.  Except  for investments in  Federal Home Loan
Bank stock and Federal National  Mortgage Association ("FNMA") stock,  ownership
of  Subsidiary shares  and except as  set forth in  Disclosure Schedule 2.01(b),
none of  the investments  reflected in  the consolidated  balance sheet  of  the
Seller  as of December 31, 1995, and none of such investments with face value in
excess of $100,000 made by it or any of its Subsidiaries since December 31, 1995
is subject to any
 
                                      I-16
<PAGE>
restriction (contractual or statutory),  other than applicable securities  laws,
that  would materially impair the ability  of the entity holding such investment
freely to dispose of such investment at any time, except to the extent any  such
investments  are  pledged  in  the ordinary  course  of  business  (including in
connection  with  hedging  arrangements   or  programs  or  reverse   repurchase
arrangements)  consistent with prudent banking practice to secure obligations of
the Seller  or any  of its  Subsidiaries. Seller  and its  Subsidiaries have  no
outstanding repurchase agreements to which Seller or Seller Bank is a party.
 
    (x)    REGISTRATION  OBLIGATIONS.    Neither  the  Seller  nor  any  of  its
Subsidiaries is under any obligation,  contingent or otherwise, to register  any
of its securities under the Securities Act or the OTS Regulations.
 
    (y)    BOOKS AND  RECORDS.   The books  and  records of  the Seller  and its
Subsidiaries have been, and are being, maintained in accordance with  applicable
legal  and  accounting requirements  and reflect  in  all material  respects the
substance of material events and transactions that should be included therein.
 
    (z)  CORPORATE DOCUMENTS.   The Seller has  delivered to the Purchaser  true
and  complete  copies of  its Certificate  of Incorporation  and Bylaws  and the
Charter and Bylaws of Seller  Bank, as amended to  date, which are currently  in
full force and effect.
 
    (aa)   ABSENCE OF KNOWLEDGE.  As of the date hereof, the Seller is not aware
of any reason  why it  would be  unable to  obtain all  the necessary  approvals
required in order to consummate the transactions contemplated by this Agreement.
 
    (bb)   SEC AND REGULATORY FILINGS.  None of the information regarding Seller
supplied or  to be  supplied by  Seller for  inclusion or  included in  (a)  the
registration statement on Form S-4 to be filed with the SEC by Purchaser for the
purpose  of registering the shares of Purchaser Common Stock to be exchanged for
shares of Seller Common Stock pursuant to the provisions of this Agreement  (the
"Registration Statement"), (b) the joint proxy statement/prospectus to be mailed
to  shareholders of  Seller and  Purchaser (the  "Proxy Statement")  and (c) any
other documents  to  be  filed  with  the SEC  or  any  Regulatory  Agencies  in
connection  with the  transactions contemplated  hereby will,  at the respective
times such documents are filed with the  SEC or any Regulatory Agencies and,  in
the  case of  the Registration  Statement, when  it becomes  effective and, with
respect to the Proxy Statement, when mailed, be false or misleading with respect
to any material fact, or omit to  state any material fact necessary in order  to
make  the statements therein not misleading or,  in the case of the Seller Proxy
Statement or any  amendment thereof or  supplement thereto, at  the time of  the
meeting  of  Seller  stockholders  referred  to in  Section  4.11,  be  false or
misleading with respect to any material fact, or omit to state any material fact
necessary to correct any statement in any earlier communication with respect  to
the  solicitation of any proxy  for such meeting. All  documents which Seller is
responsible for  filing  with  the  SEC or  any  other  Regulatory  Agencies  in
connection  with the  Merger will  comply as  to form  in all  respects with the
provisions of applicable law.
 
    (cc)  TAX TREATMENT.   To the best knowledge  of the Seller, neither  Seller
nor  any  Seller  Subsidiary has  engaged  in  any act  that  would  preclude or
adversely affect the Merger from  qualifying as a tax-free reorganization  under
Section 368(a) of the Code.
 
    (dd)    INDEMNIFICATION.   To the  best  knowledge of  Seller, no  action or
failure to take action by any director, officer, employee or agent of Seller  or
Seller Bank has occurred which would give rise to a Claim by any such person for
indemnification  from Seller or Seller  Bank under the corporate indemnification
provisions of Seller or  Seller Bank in  effect on the  date of this  Agreement,
which  are  reasonably  likely, individually  or  in  the aggregate,  to  have a
Material Adverse Effect on the Seller or its Subsidiaries.
 
    SECTION 2.02    REPRESENTATIONS  AND  WARRANTIES  OF  THE  PURCHASER.    The
Purchaser  represents and  warrants to  the Seller  that except  as disclosed in
schedules   of   the    Purchaser   delivered   to    the   Seller   prior    to
 
                                      I-17

incorporation or organization. Each of the Purchaser and its subsidiaries is  in
good standing as a foreign corporation in each jurisdiction where the properties
owned,  leased  or operated,  or  the business  conducted,  by it  requires such

its subsidiaries each has the requisite corporate and other power and  authority
(including  all federal, state, local and foreign government authority) to carry
on its respective business as they are now being conducted and to own, lease and
operate their respective properties and assets. The deposits of the subsidiaries
of the Purchaser are insured by the  Bank Insurance Fund ("BIF") or the SAIF  of

           shares of common stock, par value $4.69 per share ("Purchaser  Common
    Stock"),  and 1,000 shares of  preferred stock, no par  value per share (the
    "Purchaser Preferred Stock").  As of  the date hereof,  4,354,138 shares  of
    Purchaser  Common  Stock and  no shares  of  Purchaser Preferred  Stock were

    nonassessable and not subject to any preemptive rights.
 
          (ii)
           Except as set forth in Disclosure Schedule 2.02(b) as of the date  of
           this  Agreement, except for this Agreement, neither the Purchaser nor
    any of  its subsidiaries  is  a party  to or  is  bound by  any  outstanding
    subscriptions,  options,  warrants, calls,  rights,  convertible securities,
    commitments or agreements of any  character obligating the Purchaser or  any
    of  its  subsidiaries to  issue, deliver  or  sell, or  cause to  be issued,
    delivered or sold, any additional shares  of capital stock of the  Purchaser
    or  any  of its  subsidiaries  or obligating  the  Purchaser or  any  of its
    subsidiaries to grant, extend or enter into any such option, warrant,  call,
    right, convertible security, commitment or agreement. As of the date hereof,
    there  are no outstanding contractual obligations of the Purchaser or any of
    its subsidiaries to repurchase,  redeem or otherwise  acquire any shares  of
    capital stock of the Purchaser or any of its subsidiaries.
 
    (c)    AUTHORITY.   The  Purchaser  has  all requisite  corporate  power and

contemplated  hereby.  The execution  and delivery  of  this Agreement,  and the
consummation of the transactions contemplated  hereby have been duly  authorized
by  all necessary corporate action on the  part of the Purchaser. This Agreement
has been  duly  executed  and  delivered by  the  Purchaser,  and  assuming  due
execution and delivery by the Seller, constitutes a valid and binding obligation
of the Purchaser, enforceable in accordance with its terms subject to applicable
conservatorship, receivership, bankruptcy, insolvency and similar laws affecting
creditors'  rights and remedies generally, and subject, as to enforceability, to
general  principles   of   equity   (including   without   limitation   specific
performance), whether applied in a court of law or a court of equity.
 
    (d)   SHAREHOLDER APPROVALS.   The Board  of Directors of  the Purchaser has
directed that  this  Agreement  and  the  transactions  contemplated  hereby  be
submitted  to the  Purchaser's shareholders  for approval  at a  meeting of such
shareholders and, except for adoption of this Agreement by the requisite vote of
the Purchaser's  shareholders,  no  other shareholder  action  is  necessary  to
approve  this Agreement and to  consummate the transactions contemplated hereby.
The Board of Directors will
 
                                      I-18
<PAGE>
recommend that  the  shareholders  approve  the  transaction  subject  to  their
fiduciary  duties  and will  exempt the  transaction  from any  applicable state
takeover statutes. The  approval of the  majority of the  outstanding shares  of
Purchaser  Common  Stock  entitled to  vote  is  required for  approval  of this
Agreement and to consummate the transactions contemplated hereby.
 
    (e)   NO VIOLATIONS.   Subject  to approval  by the  appropriate  Regulatory
Agencies,  the  execution, delivery  and performance  of  this Agreement  by the
Purchaser do not, and the  consummation of the transactions contemplated  hereby
will  not, constitute (i) a breach or violation of, or a default under, any law,
rule or  regulation  or any  judgment,  decree, order,  governmental  permit  or
license,  or  agreement,  indenture  or  instrument  of  the  Purchaser  or  any
subsidiary or  to  which  the Purchaser  or  any  subsidiary (or  any  of  their
respective  properties)  is subject,  which breach,  violation or  default would
individually or in the aggregate, have a Material Adverse Effect on Purchaser or
on Purchaser's ability to consummate the transaction's contemplated hereby  (ii)
a  breach or violation of, or a default under, the certificate of incorporation,
charter or bylaws of the Purchaser or any subsidiary of the Purchaser or (iii) a
breach or violation of, or a default under (or an event which with due notice or
lapse of  time or  both would  constitute a  default under),  or result  in  the
termination  of,  accelerate  the  performance required  by,  or  result  in the
creation of any  lien, pledge,  security interest, charge  or other  encumbrance
upon  any of the properties  or assets of the Purchaser  under any of the terms,
conditions or  provisions of  any note,  bond, indenture,  deed of  trust,  loan
agreement or other agreement, instrument or obligation to which the Purchaser is
a  party, or to which any of its respective properties or assets may be bound or
affected, except  for  any  of  the  foregoing  that,  individually  or  in  the
aggregate, would not have a Material Adverse Effect on the Purchaser.
 
    (f)    CONSENTS.   Except  as referred  to herein  or  in connection,  or in
compliance, with the Securities  Act, the Exchange Act,  the HOLA, the BMA,  the
rules  and  regulations of  the Federal  Reserve  Board, and  the environmental,
corporation, securities or blue sky laws  or regulations of the various  states,

public body or authority is necessary  for the consummation by the Purchaser  of
the  Merger or the other transactions contemplated by this Agreement, other than
filings, registrations, authorizations,  consents or approvals,  the failure  to
make or obtain would not have a Material Adverse Effect on the Purchaser.
 
    (g)  REPORTS.
 
           (i)
           As  of their respective dates,  neither the Purchaser's Annual Report
           on Form 10-K  for the fiscal  year ended December  31, 1995, nor  any
    other  document filed subsequent to December  31, 1995 under Sections 13(a),
    13(c), 14 or  15(d) of the  Exchange Act,  each in the  form (including  any
    documents  specifically incorporated  by reference  therein) filed  with the
    SEC, (collectively, the  "Purchaser's Reports"), contained  or will  contain
    any  untrue statement of a material fact or  omitted or will omit to state a
    material fact  required  to be  stated  therein  or necessary  to  make  the
    statements made therein, in light of the circumstances under which they were
    made,  not  misleading, PROVIDED,  HOWEVER, that  no representation  is made
    herein with respect to  any Exhibits to the  Purchaser Reports that are  not
    specifically   incorporated  by  reference   therein  and  that  Purchaser's
    amendment of any Purchaser's  Report, in and of  itself, in response to  SEC
    comments  will not be violative of this  section. Each of the balance sheets
    of the Purchaser or its subsidiaries contained or specifically  incorporated
    by  reference in the Purchaser's Reports (including in each case any related
    notes and schedules) fairly presented  the financial position of the  entity
    or entities to which it relates as of its date and each of the statements of
    income  and  of  changes  in  stockholders' equity  and  cash  flows  of the
    Purchaser or  its subsidiaries  contained  or specifically  incorporated  by

of  Chapter 61 of  the Code and  similar applicable state  and local information

knowledge, no such Claim has been threatened. Except as set forth in  Disclosure

    (m)  EMPLOYEE BENEFIT PLANS.
 
           (i)
           The  Purchaser and  its subsidiaries  maintain various  plans for the
           benefit  of  employees,  except   for  any  such  plans,   contracts,
    agreements  or arrangements involving liabilities  or expenses not exceeding
    $10,000 individually or in the aggregate which are herein after referred  to
    collectively  as "Purchaser Employee  Plans." All of  the Purchaser Employee
    Plans comply in all  material respects with  all applicable requirements  of
    ERISA,  the Code and  other applicable laws,  orders, rules and regulations;
    neither the  Purchaser  nor  any  of  its  subsidiaries  has  engaged  in  a
    "prohibited transaction" (as defined in Section 406 of ERISA or Section 4975
    of  the Code) with respect to any Purchaser Employee Plan. Purchaser and its
    subsidiaries have  complied  with  the  health  care  continuation  coverage
    requirements  of Section 4980B of  the Code and Sections  601 through 608 of
    ERISA. No liability  to the  Pension Benefit Guaranty  Corporation has  been
    incurred  and,  except as  described on  Disclosure Schedule  2.02(m), there
    exists no fact or circumstance which would cause the Purchaser to incur  any
    such  liability with respect to any Purchaser Employee Plan which is subject
    to  Title  IV   of  ERISA  ("Pension   Plan"),  or  with   respect  to   any
    "single-employer   plan"  (as  defined  in  Section  4001(a)(15)  of  ERISA)
    currently or formerly  maintained by the  Purchaser or any  entity which  is
    considered  one employer with  the Purchaser under Section  4001 of ERISA or
    Section 414  of the  Code (an  "ERISA Affiliate").  Except as  described  on
    Disclosure  Schedule 2.02(m),  no Pension  Plan had  an "accumulated funding
    deficiency" (as defined in Section 302 of ERISA (whether or not waived))  as
    of  the last day of the end of the most recent plan year ending prior to the
    date hereof; the present value of  the "benefit liabilities" (as defined  in
    Section 4001(a)(16) of ERISA) under each Pension Plan as of the date hereof,
    calculated on the basis of the actuarial assumptions used in the most recent
    actuarial  valuation for such  Pension Plan as  of the date  hereof does not
    exceed the fair  market value of  the assets  of such Pension  Plan, and  no
    notice  of a "reportable  event" (as defined  in Section 4043  of ERISA) for
    which the 30-day reporting requirement has not been waived has been required
    to be filed for any  Pension Plan within the  12-month period ending on  the
    date  hereof. Neither the Purchaser nor  any Subsidiary of the Purchaser has
    provided, or is required to provide, security to any Pension Plan or to  any
    single-employer plan of an ERISA Affiliate pursuant to Section 401(a)(29) of
    the  Code. Neither the Purchaser, its  subsidiaries, nor any ERISA Affiliate
    currently contributes or, since  December 31, 1988,  has contributed to  any
    multiemployer  plan, as  defined in Section  3(37) of  ERISA. Each Purchaser
    Employee Plan of the  Purchaser or of  any of its  subsidiaries which is  an
    employee  "pension benefit plan"  (as defined in Section  3(2) of ERISA) and
    which is  intended to  be qualified  under  Section 401(a)  of the  Code  (a
    "Qualified Plan") has received a favorable determination letter from the IRS
    that  the pension  benefit plan  meets the  Tax Reform  Act of  1986 and all
    applicable legislative  and regulatory  requirements for  tax  qualification
    that  became effective at the time  that the determination letter was issued
    and the Purchaser and  its subsidiaries are not  aware of any  circumstances
    which would result in revocation of any such favorable determination letter.
    Each  Qualified  Plan  which  is  an  "employee  stock  ownership  plan" (as
 
                                      I-21
<PAGE>

licenses, certificates,  permits, franchises  and  rights from  all  appropriate
federal,  state or other public authorities necessary for the conduct of its and
their business as  it is presently  conducted except where  the absence  thereof

          (ii)
           The Purchaser and its subsidiaries are in substantial compliance with
           all  applicable  Environmental Laws.  Neither  the Purchaser  nor its

    Purchaser's  consolidated business, financial condition or prospects. (iv)To
    the best knowledge of the Purchaser after due inquiry, the Purchaser and its
    subsidiaries  have  all  governmental  permits,  licenses,  certificates  of

    (r)  LOANS AND INVESTMENTS.
 
           (i)
           Except as set forth in Disclosure Schedule 2.02(r), each  outstanding
           loan of Purchaser or any of its subsidiaries as of the date hereof is
    evidenced  by appropriate  and sufficient documentation  and constitutes the
    legal,  valid  and  binding  obligation   of  the  obligor  named   therein,
    enforceable  in  accordance with  its terms  except to  the extent  that the
    enforceability  thereof   may   be  limited   by   bankruptcy,   insolvency,
    reorganization, moratorium or similar laws or equitable principles affecting
    the  rights  of  creditors  generally  except where  the  failure  to  be so
    documented or to constitute a legal,  valid and binding obligation will  not
    have  a Material Adverse  Effect upon the  business, operations or financial
    condition of  Purchaser  or  its  subsidiaries. To  the  best  knowledge  of
    Purchaser and its subsidiaries, no obligor named therein is seeking to avoid
    the enforceability of the terms of any loan under any such laws or equitable
    principles  and no  loan is subject  to any defense,  offset or counterclaim

           To  the  best  knowledge  of  Purchaser  and  its  subsidiaries,  all
           guarantees  of indebtedness  owed to  Purchaser or  its subsidiaries,
    including but not limited to those of state or federal agencies, are,  valid
    and  enforceable, except to the extent enforceability thereof may be limited
    by applicable bankruptcy, insolvency, reorganization, moratorium or  similar
    laws or equitable principles affecting the rights of creditors generally and
    except  as would  not have  a Material Adverse  Effect on  Purchaser and its
    subsidiaries on a consolidated basis.
 
                                      I-23
<PAGE>
         (iii)
           To  the  best  knowledge  of  Purchaser  and  its  subsidiaries,   in
           originating,   underwriting,   servicing,   and   discharging  loans,
    mortgages, land  contracts, and  other contractual  obligations, either  for
    their  own  account  or  for  the  account  of  others,  Purchaser  and  its
    subsidiaries have complied with all applicable terms and conditions of  such
    obligations  and with  all applicable laws,  regulations, rules, contractual
    requirements, and procedures  with respect to  such servicing, except  where
    the  failure  to  comply  would  not have  a  Materially  Adverse  Effect on
    Purchaser and its subsidiaries on a consolidated basis.
 
    (s)  ALLOWANCE FOR LOAN LOSSES.  In the Purchaser's reasonable judgment, the
allowance for  loan losses  reflected in  the Purchaser's  audited statement  of
condition  at December 31, 1995 was, and  the allowance for loan losses shown on
the balance sheets in the Purchaser's Reports for periods ending after  December
31,  1995 have been  and will be, adequate  in all material  respects, as of the
dates thereof,  under generally  accepted  accounting principles  applicable  to
state  banks and  federal savings banks  as the  case may be.  The Purchaser has
disclosed to  the Seller  the amounts  of all  loans, leases,  advances,  credit
enhancements,  other  extensions  of  credit,  commitments  and interest-bearing
assets of the  Purchaser and its  subsidiaries that have  been classified as  of
December  31,  1995 as  "Other  Loans Specially  Mentioned,"  "Special Mention,"
"Substandard," "Doubtful,"  "Loss,"  "Classified,"  "Criticized,"  "Credit  Risk
Assets," "Concerned Loans" (in the latter two cases, to the extent available) or
words  of similar import. The  REO included in any  non-performing assets of the
Purchaser or any of its subsidiaries is carried net of reserves at the lower  of
cost or fair value.
 
    (t)    MATERIAL  INTERESTS OF  CERTAIN  PERSONS.   Except  as  set  forth in
Disclosure Schedule 2.02(t), to Purchaser's knowledge, no officer or director of
the Purchaser has  any material interest  in any material  contract or  property
(real  or  personal),  tangible or  intangible,  used  in or  pertaining  to the
business of the Purchaser or any of  its subsidiaries that would be required  to
be disclosed under the SEC's Regulation S-K.
 
    (u)   INSURANCE.  The Purchaser  and its subsidiaries are presently insured,
and since  December 31,  1995 have  been insured,  for reasonable  amounts  with
financially  sound  and reputable  insurance  companies, against  such  risks as
companies engaged in a similar business located in the State of Illinois  would,
in  accordance with good business practice, customarily be insured. All material
claims thereunder have been filed in  due and timely fashion. Neither  Purchaser
nor  its subsidiaries has any knowledge of any inaccuracy in any application for
such policies or binders, any  failure to pay premiums  when due or any  similar
state  of facts  that might  form the  basis for  termination of  such insurance
except where such failure would not have a Material Adverse Effect on  Purchaser
and its subsidiaries on a consolidated basis.
 
    (v)    REGISTRATION  OBLIGATIONS.   Neither  the  Purchaser nor  any  of its
subsidiaries is under any obligation,  contingent or otherwise, to register  any
of its securities under the Securities Act or the OTS Regulations.

legal  and  accounting requirements  and reflect  in  all material  respects the
substance of material events and transactions that should be included therein.
 
    (x)  CORPORATE DOCUMENTS.   The Purchaser has  delivered to the Seller  true
and complete copies of the Purchaser's and each of its subsidiaries' certificate
of  incorporation, charter and bylaws  as amended to date  and currently in full
force and effect.
 
    (y)  ABSENCE  OF KNOWLEDGE.   As of the  date hereof, the  Purchaser is  not
aware  of any  reason why  it would  be unable  to obtain  all of  the necessary
regulatory  approvals  required   in  order  to   consummate  the   transactions
contemplated  by this Agreement. As of the date of this Agreement, the Purchaser
believes that, in light of its financial  condition, it shall be able to  obtain
all such approvals, without the imposition of any burdensome term or condition.

    (z)   BENEFICIAL OWNERSHIP OF  SELLER COMMON STOCK.   As of the date hereof,
neither the Purchaser nor any subsidiary or affiliate thereof beneficially  owns
any shares of Seller Common Stock or, other than contemplated by this Agreement,
have  any  option,  warrant or  right  of  any kind  to  acquire  the beneficial
ownership of  any shares  of Seller  Common Stock  other than  as set  forth  in
Disclosure Schedule 2.02(z).
 
    (aa)  SEC & REGULATORY FILINGS.  None of the information regarding Purchaser
and  its subsidiaries supplied or  to be supplied by  Purchaser for inclusion or
included in (i) the Registration Statement,  (ii) the Proxy Statement, or  (iii)
any  other documents  to be  filed with  the SEC  or any  Regulatory Agencies in
connection with the  transactions contemplated  hereby will,  at the  respective
times  such documents are filed with the  SEC or any Regulatory Agencies and, in
the case of  the Registration  Statement, when  it becomes  effective and,  with
respect to the Proxy Statement, when mailed, be false or misleading with respect
to  any material fact, or omit to state  any material fact necessary in order to
make the  statements  therein  not misleading  or,  in  the case  of  the  Proxy
Statements  or any amendment thereof  or supplement thereto, at  the time of the
meeting of the stockholders referred to in Section 4.11, be false or  misleading
with  respect to any material fact, or omit to state any material fact necessary
to correct  any statement  in  any earlier  communication  with respect  to  the
solicitation  of any proxy  for such meeting. All  documents which Purchaser and
its subsidiaries are  responsible for  filing with  the SEC  and any  Regulatory
Agencies  in connection with the  Merger will comply as  to form in all material
respects with the provisions of applicable law.
 
    (bb)  TAX TREATMENT.   To the  best of the  knowledge of Purchaser,  neither
Purchaser  nor any  Subsidiary has  engaged in  any act  that would  preclude or
adversely affect the Merger from  qualifying as a tax-free reorganization  under
Section 368(a) of the Code.
 
    (cc)   AFFILIATE PURCHASES.  Affiliates of the Purchaser or its subsidiaries
including, but not limited to, officers, employees, directors, and greater  than
10%  beneficial owners have not purchased  any Purchaser Common Stock during the
ten (10) trading days on which one or more trades actually occurred  immediately
prior to the execution of this Agreement.
 
    (dd)   INDEMNIFICATION.   To the best  knowledge of Purchaser,  no action or
failure to take action by any director, officer, employee or agent of  Purchaser
or  its subsidiaries has occurred  which would give rise to  a Claim by any such
person  for  indemnification  from  Purchaser  or  its  subsidiaries  under  the
corporate  indemnification provisions of Purchaser or its subsidiaries in effect
on the date of this Agreement,  which are reasonably likely, individually or  in
the  aggregate,  to have  a  Material Adverse  Effect  on the  Purchaser  or its
subsidiaries.

of  the  Purchaser or  any  of its  subsidiaries  to perform  its  covenants and
agreements under this Agreement or  to consummate the transactions  contemplated
hereby,  (ii)  take  any  action  which would  materially  affect  or  delay the

ability of  the Seller  or  the Purchaser  to  obtain any  necessary  approvals,
consents  or waivers of any governmental authority required for the transactions

distributions  in  respect of,  the Purchaser  Common  Stock except  for regular
dividends and dividends or distributions  in Purchaser Common Stock, (iv)  amend
its  Certificate  of  Incorporation  or  Bylaws  or  other  corporate governance
documents, or (v) authorize or enter into any agreement or commitment to do  any
of  the  foregoing.  Except as  expressly  provided in  the  preceding sentence,
nothing contained herein shall limit Purchaser nor any of its subsidiaries  from
entering  into agreements to acquire (i) the stock or assets of any other entity
except that  the  Purchaser  shall  not enter  into  an  agreement  which  would
materially  affect or  delay the  ability of  Purchaser to  obtain any necessary
regulatory approvals or consummate the transactions contemplated hereby or  (ii)
outstanding  shares of Purchaser Common Stock consistent with past practices, so
long as such purchases  of Purchaser Common Stock  are consummated prior to  the
time period contemplated by Section 1.02(d).

accountant  retained by the Seller or any of its Subsidiaries) will, directly or
indirectly, initiate, solicit or knowingly encourage any inquiries or the making
of any proposal or offer (including,  without limitation, any proposal or  offer

Proposal"). The Seller shall notify  Purchaser promptly of the relevant  details
relating  to all inquiries and proposals which it may receive relating to any of
such matters; PROVIDED, HOWEVER, that, notwithstanding the foregoing, the Seller

confidential  information or data  to, or have any  discussions with, any person
related to  an  Acquisition Proposal,  or  otherwise facilitate  any  effort  to
attempt  to make or implement an Acquisition Proposal, if the Board of Directors
of the Seller, after  consultation with its outside  counsel, determines in  the
exercise of its fiduciary responsibilities that such discussions or negotiations
should be commenced or such information should be furnished or such facilitation
undertaken.  Subject to the foregoing, (i) the Seller will immediately cease and
cause to be terminated any existing activities, discussions or negotiations with
any parties conducted heretofore with respect  to any of the foregoing or  which
are otherwise in contemplation of an acquisition transaction and (ii) the Seller
will  take the necessary steps to inform the appropriate individuals or entities

       Purchaser acknowledges  that  for purposes  of  any agreement  listed  on
       Schedule  4.02(c)  conferring rights  on  an employee  as  a result  of a
"change in control", the Merger shall constitute a change in control;
 
       (iii)

<PAGE>
    (b)   CONVERSION OF SELLER STOCK OPTIONS  INTO PURCHASER COMMON STOCK.  Each
Seller Stock Option shall be converted at the Effective Time into such number of

(i) the product of the number of shares of Seller Common Stock subject to Seller
Stock Options, the  Exchange Ratio and  the Purchaser Average  Stock Price  less

Stock subject to Seller Stock Options. No fractional shares shall be issued  and

assets,  books and records and personnel,  except for materials that are legally
privileged or which the Seller and  its Subsidiaries are prohibited by law  from
disclosing,  during  normal  business  hours and  after  reasonable  notice; and
Purchaser shall be  provided with such  financial and operating  data and  other

manner so as not to interfere  with normal operations and consumer and  employee
relationships  of Seller and its Subsidiaries. In the event the Purchaser learns
of any  information or  matters  during such  investigation that  the  Purchaser
believes  may constitute  or reveal  a material  breach of  the Seller's  or its
Subsidiaries representations,  warranties,  covenants  or  agreements  contained
herein,  the Purchaser shall provide the Seller  with a written notice within 15
business days, specifying the information or matters learned and the basis  upon
which  they  may  constitute  or  reveal  a  material  breach  of  the  Seller's
representations, warranties, covenants or agreements  and the Seller shall  have
the  right to cure such material breach within 30 calendar days from the date of
such notice or  such longer period  as extended  by the parties  in writing.  No
breach  of a  representation, warranty,  covenant or  agreement that  is learned
pursuant to Purchaser's  investigation contemplated by  this Section 4.04  shall
constitute  a  material  breach  of  a  representation,  warranty,  covenant  or
agreement by  Seller or  its Subsidiaries  under  any provision  of or  for  any
purpose  under this  Agreement and  the information  or matters  underlying such
breach shall  be deemed  to have  been fully  disclosed in  Seller's  disclosure
pursuant  to this  Agreement, unless  Purchaser provides  Seller with  a written
notice relating  thereto delivered  and the  Seller has  not cured  such  breach
within  the  time  period provided  in  the immediately  preceding  sentence and
Purchaser exercises its right to terminate  this Agreement on the basis  thereof
in accordance with Section 6.01(e).
 
    (b)Each  party hereto shall  treat as strictly  confidential all information
       received from the other party and shall not divulge to any other  person,
natural  or corporate (other than essential  employees and agents of each party)
any financial statements, schedules, contracts, agreements, instruments, papers,
documents and other information relating to the other party which it may come to
know or which may come into its possession and, if the transactions contemplated
hereby are not consummated  for any reason, shall  promptly return to the  other
party all material furnished by the other party.
 
    (c)Each  party  hereto  shall  will  not,  and  will  cause  its  respective
       representatives not to, use any information obtained from any other  such
party  as  a  result of  this  Agreement  (including this  Section  4.04)  or in
connection with the transactions contemplated hereby (whether so obtained before
or after the execution hereof, including work papers and other materials derived
therefrom  (collectively,  the  "Confidential  Information"))  for  any  purpose
unrelated   to  the  consummation  of  the  transactions  contemplated  by  this
Agreement. Subject  to  the  requirements  of  law,  regulation  and  applicable
Regulatory  Agencies, each party  hereto will keep  confidential, and will cause
its  respective   representatives  to   keep  confidential,   all   Confidential
Information relating to or furnished by any other
 
                                      I-31

such  party unless  such information  (i) was  already or  becomes known  to the
general public,  other than  from a  prohibited disclosure  by a  party to  this
Agreement  or its  representatives, (ii) becomes  available to such  party or an
affiliate of such party from sources (other than another party to this Agreement
or its representatives) not bound by a confidentiality obligation or  agreement,
(iii)  is disclosed with the prior written approval of the party which furnished
such Confidential Information or (iv)  is or becomes readily ascertainable  from
published  information. In  the event that  this Agreement is  terminated or the

consummated, each party hereto and its respective representatives shall promptly
cause  all  Confidential  Information  in  the  possession  of  itself  and  its
representatives, including all copies or extracts thereof, to be returned to the
party which furnished the same.
 
    SECTION 4.05  CERTAIN FILINGS, CONSENTS AND ARRANGEMENTS.  The Purchaser and
the Seller shall, (a) make as soon as practicable (or cause to be made) from the

required  to be filed in order to  obtain all approvals, consents and waivers of
governmental authorities necessary  or appropriate for  the consummation of  the
transactions contemplated hereby, (b) cooperate with one another (i) in promptly
determining  what  filings are  required to  be made  or approvals,  consents or

which it is prohibited by law from disclosing) promptly after they are filed.
 
    SECTION 4.06  ANTITAKEOVER PROVISIONS.  Subject to the continued accuracy of
the Purchaser's representation  in Section 2.02(p)  and to the  exercise of  the
fiduciary  duties of the Seller's Board  of Directors as contemplated by Section
4.01, the Seller and its Subsidiaries  shall use reasonable best efforts (i)  to
continue  to  exempt  the  Purchaser,  the Agreement  and  the  Merger  from any
provisions of  an  antitakeover nature  in  the Seller's  or  its  Subsidiaries'
charters  and bylaws  and the  provisions of  any federal  or state antitakeover
laws, and (ii) upon the  reasonable request of the  Purchaser, to assist in  any
challenge  by the Purchaser to the applicability  to the Agreement or the Merger
of any state antitakeover law.
 
    SECTION 4.07  ADDITIONAL AGREEMENTS.  Subject to the terms and conditions of
this Agreement, each of the parties hereto agrees to use all reasonable  efforts
to take promptly, or cause to be taken promptly, all actions and to do promptly,

public  disclosure with  respect to the  other or  the transactions contemplated
hereby and  in making  any filings  with  any governmental  entity or  with  any
national  securities  exchange  with respect  thereto;  PROVIDED,  HOWEVER, that
nothing contained in this Section 4.08 shall prohibit any party from  responding
to  questions from  the business press  or, following notification  to the other
parties to this Agreement, from making any disclosure which, after  consultation
with  its  counsel,  it  deems  necessary to  comply  with  the  requirements of

hand,  and the Seller and the Seller Bank,  on the other hand, shall give prompt
notice to the  other of  (a) the  occurrence or its  knowledge of  any event  or
condition that would cause any of its representations or warranties set forth in
this  Agreement not to  be true and correct  in all material  respects as of the
date of  this  Agreement  or  as  of  the  Effective  Time  (except  as  to  any
representation  or warranty which  specifically relates to  an earlier date), or
any of its obligations set forth in  this Agreement required to be performed  at
or  prior to the Effective Time not to  be performed in all material respects at
or prior to  the Effective  Time (any  such notice,  a "Supplemental  Disclosure
Schedule"),  including  without  limitation,  any  event,  condition,  change or
occurrence which  individually or  in the  aggregate has,  or which,  so far  as
reasonably  can be foreseen at the time  of its occurrence, is reasonably likely

party  of which it receives notice that  might reasonably be expected to prevent
or materially delay  the consummation of  the transactions contemplated  hereby,
including,  without limitation, any notice or other communication from any third
party alleging that the  consent of such  third party is or  may be required  in
connection   with  the   transactions  contemplated   by  this   Agreement.  Any
Supplemental Disclosure Schedule given by one party to the other party shall  be
deemed  to amend  the Disclosure Schedule  and, unless the  party receiving such
amended Disclosure Schedule, by written notice  to the other party given  within
fifteen  (15)  business  days of  its  receipt of  such  Supplemental Disclosure
Schedule, exercises any  right of  termination it  may then  have under  Section
6.01(b),  and subject to the cure period  set forth in 6.01(b), that party shall
thereafter be deemed to  have permanently and irrevocably  waived (on behalf  of
itself  and its subsidiaries) (i) any right  of termination (or any other rights
or remedies)  arising  out  of or  with  respect  to the  events  or  conditions
described in such Supplemental Disclosure Schedule; and (ii) any contribution of

    SECTION 4.10  INDEMNIFICATION.
 
    (a)From  and after the  Effective Time through the  sixth anniversary of the
       Effective Date, the Purchaser agrees to indemnify and hold harmless  each
present and former director and officer of the Seller or its Subsidiaries (each,
an  "Indemnified Party"),  against any  costs or  expenses (including reasonable
attorneys' fees),  judgments,  fines,  losses, claims,  damages  or  liabilities
(collectively, the "Costs") incurred in connection with any claim, action, suit,
proceeding   or  investigation,  whether   civil,  criminal,  administrative  or
investigative, and whether  or not  the Indemnified  Party is  a party  thereto,
arising  out of matters existing or occurring  at or prior to the Effective Time
(including the transactions contemplated by this Agreement), whether asserted or
claimed prior to, at  or after the  Effective Time, to  the fullest extent  then
permitted  under Delaware law  or, if greater,  that the Seller  would have been
permitted under its certificate of incorporation, charter or bylaws in effect on
the date hereof, and to advance any such costs to each Indemnified Party as they
are from time to time  incurred (subject to receipt  of an undertaking to  repay
such  advances if it  is ultimately judicially  determined that such Indemnified
Party is not entitled to indemnification); provided that if a court of competent
jurisdiction finds that the Indemnified Party is not permitted  indemnification,
then  the Purchaser  will not  be liable  for the  expenses of  such Indemnified
Party.
 
    (b)Any Indemnified  Party wishing  to  claim indemnification  under  Section
       4.10(a),  upon learning  of any such  claim, action,  suit, proceeding or
investigation, shall promptly notify the  Purchaser thereof, but the failure  to
so notify shall not relieve the Purchaser of any liability it may have hereunder
to  such Indemnified Party if such failure does not materially and substantially
prejudice the indemnifying party. In the event of any such claim, action,  suit,
proceeding  or investigation, (i)  the Purchaser shall have  the right to assume
the defense thereof with counsel reasonably acceptable to the Indemnified  Party
and  the Purchaser shall not  be liable to such  Indemnified Party for any legal
expenses of other  counsel subsequently  incurred by such  Indemnified Party  in
connection  with the  defense thereof,  except that  if the  Purchaser elects to

matter  and (iii) the Purchaser shall not  be liable for any settlement effected
by an Indemnified Party without its prior written consent, which consent may not

holders of Seller Common Stock in the Merger, which Registration Statement shall
include the Proxy Statement for use in soliciting proxies for the  shareholders'
meeting  to be held by  the Purchaser and Seller  for the purpose of considering
the Merger, and Purchaser and Seller shall  use their best efforts to cause  the

<PAGE>
Act. Seller shall use its reasonable efforts to cause each person to deliver  to
Purchaser  not later than thirty (30) calendar days prior to the Effective Time,
a written agreement, substantially in the  form of EXHIBIT A to this  Agreement,
providing that such person will not sell, pledge, transfer, or otherwise dispose

    SECTION  4.14   TAX OPINION.   The Purchaser  and Seller agree  to use their

such  other  counsel reasonably  acceptable to  both  parties, addressed  to the
Purchaser  and  Seller,  dated  the  Closing  Date,  subject  to  the  customary
representations  and assumptions referred  to therein, and  substantially to the
effect that (a) the Merger will constitute a tax-free reorganization within  the
meaning  of  Section 368(a)  of  the Code;  (b) the  exchange  in the  Merger of
Purchaser Common Stock will not give rise to gain or loss to the stockholders of
the Seller  with respect  to the  exchange (except  to the  extent of  any  cash

reorganization within the meaning  of Section 368(a) of  the Code. In  rendering

use  its best  efforts to cause  the Merger, and  to take no  action which would
cause the Merger not to qualify  for treatment as a "reorganization" within  the
meaning of Section 368(a) of the Code.
 
    SECTION  4.15  TAX-FREE REORGANIZATION TREATMENT.   Prior to Effective Time,
neither the Purchaser nor the Seller  shall intentionally take, fail to take  or
cause  to be taken or not take any action which would disqualify the Merger as a
"reorganization" within the meaning of Section 368(a) of the Code.

beneficial owners agree not  to purchase any Purchaser  Common Stock during  the

    Seller,  to the  effect that  no facts  have come  to the  attention of such
    counsel, with respect to information provided by Seller for inclusion in the
    Proxy Statement, which  would lead such  counsel to believe  that the  Proxy
    Statement,  and  any supplement  or amendment  thereto, on  the date  of the
    mailing thereof and on  the date of the  meeting of stockholders of  Seller,
    contained  any untrue statement of  a material fact or  omitted to state any

    made, not misleading (it being understood that such counsel need express  no
    opinion with respect to the fairness opinion, financial statements and notes
    thereto and other financial, statistical and accounting information included
    in the Proxy Statement); PROVIDED, HOWEVER, that such counsel may state that
    they  have not independently verified the accuracy, completeness or fairness
    of the  statements contained  in the  Proxy Statement,  and the  limitations
    inherent  in their participation  in the preparation  of the Proxy Statement
    and that the knowledge  available to them  is such that  they are unable  to
    assume,  and do not assume, responsibility for the accuracy, completeness or

       that challenge the validity or legality of the transactions  contemplated
       by  the  Agreement  or which  seek  or  threaten to  restrain,  enjoin or
       prohibit (or  to  obtain  substantial damages  in  connection  with)  the
       consummation of such transactions;
 
            (vii)
               all  regulatory and governmental approvals and consents which are

       form  in all material respects with the applicable provisions of law with

       validly  issued,  fully  paid and  nonassessable,  and no  holder  of any
       presently outstanding shares of Purchaser Common Stock has any preemptive
       or similar rights to subscribe for or purchase any such shares.
 
       (e) the Purchaser  shall  have  received  a letter,  dated  the  date  of
           Closing,  from Burke, Warren & MacKay,  P.C. counsel to Purchaser, to

    amendments thereto, on the date of  the mailing of the Proxy Statement,  and
    on  the date of the meeting of  stockholders of Seller, contained any untrue
    statement of a material fact or omitted to state any material fact  required
    to  be stated therein or necessary to made the statements contained therein,

    statements  contained in the Proxy Statement and the Registration Statement,
    and the limitations inherent  in their participation  in the preparation  of
    the  Proxy Statement and  the Registration Statement  and that the knowledge
    available to them is such that they are unable to assume, and do not assume,
    responsibility for the accuracy, completeness or fairness of the  statements
    contained in the Proxy Statement and the Registration Statement.

       (f) the   Purchaser  shall  have  furnished   to  the  Seller  with  such

                                  TERMINATION
 
    SECTION  6.01   TERMINATION.   Notwithstanding any  other provision  of this
Agreement, this Agreement may be terminated, and the Merger abandoned, prior  to
the  Effective Time, either before or after  its approval by the shareholders of
the Seller:
 
       (a) by the mutual consent  of the Purchaser and  the Seller in a  written
           instrument  if the board of directors of each so determines by a vote
    of a majority of the members of its entire board;
 
       (b) by the  Purchaser or  the  Seller (provided  that the  party  seeking
           termination  is not  then in  material breach  of any representation,
    warranty, covenant or other agreement contained  herein), in the event of  a
    failure  to  perform or  comply  by the  other  party with  any  covenant or
    agreement of such other party contained in this Agreement, which failure  or
    non-compliance  is material in the  context of the transactions contemplated
    by this  Agreement,  or (ii)  subject  to Section  4.09,  any  inaccuracies,
    omissions  or  breach  in  the  representations,  warranties,  covenants  or
    agreements of the other party contained in this Agreement the  circumstances
    as  to which  either individually  or in  the aggregate  have, or reasonably
    could be expected to have, a Material Adverse Effect on such other party; in
    either case which has not  been or cannot be  cured within 30 calendar  days
    after  written notice thereof is given by  the party seeking to terminate to
    such other party.
 
       (c) by the Purchaser or the Seller  by written notice to the other  party
           if  either  (i) any  approval, consent  or  waiver of  a governmental
    authority required to permit  consummation of the transactions  contemplated
    hereby  shall  have  been  denied  or  (ii)  any  governmental  authority of
    competent  jurisdiction  shall  have  issued  a  final,  unappealable  order
    enjoining   or  otherwise  prohibiting   consummation  of  the  transactions
    contemplated by this Agreement, or (iii) the holders of Seller Common  Stock
    or  the  Purchaser  Common  Stock  shall  fail  to  approve  and  adopt this
    Agreement, PROVIDED,  HOWEVER,  that  no  party  shall  have  the  right  to
    terminate  this Agreement pursuant to this Section 6.01(c) if such denial or
    request or recommendation for withdrawal shall be due to the failure of  the
    party  seeking  to  terminate  this  Agreement  to  perform  or  observe the
    covenants and agreements of such party set forth herein;
 
       (d) by the Purchaser or the Seller, in  the event that the Merger is  not
           consummated  by March 31, 1997, unless the failure of such occurrence
    is due to the failure  to perform or comply  with any covenant or  agreement
    contained in this Agreement by the party seeking to terminate;
 
       (e) subject  to Section 4.09,  by the Purchaser by  written notice to the
           Seller in the event  that there has occurred  since the date of  this
    Agreement  an event, condition, change  or occurrence which, individually or
    in the aggregate, has  had or could  reasonably be expected  to result in  a
    Material  Adverse Effect on the Seller or the Seller Bank; PROVIDED that the
    Purchaser shall  have  given the  Seller  thirty (30)  calendar  days  prior
    written  notice of such termination, and  the Seller shall not have remedied
    such event, condition, change  or occurrence by the  end of such  thirty-day
    period  and  PROVIDED, further  that  any exclusions  from  Material Adverse
    Effect under Section 2.01(h) shall not be deemed an event that would  permit
    Purchaser to terminate this Agreement;
 
       (f) by  Purchaser in  accordance with  Section 1.02(c)(i)  upon notice to
           Seller;
 
       (g) by Seller  in  accordance with  Section  1.02(c)(ii) upon  notice  to
           Purchaser; or
 
                                      I-40
<PAGE>
       (h) by  the Purchaser by written notice to the Seller five (5) days prior
           to the Closing Date in the event  that there has been a reduction  of
    the  value  as  of that  date  of  the Bennett  Portfolio,  as  described in
    Disclosure Schedule  6.01(h),  in excess  of  a threshold  amount  equal  to
    $375,000  before any tax savings (the "Threshold Amount") ("Bennett Material
    Adverse Change"); PROVIDED, HOWEVER, that Purchaser shall not have an option
    to terminate pursuant to this  paragraph (h) if no  later than two (2)  days
    prior  to  the  Closing  Date,  the  Seller  agrees  to  reduce  the  Merger
    Consideration by the amount of the Bennett Material Adverse Change in excess
    of the  Threshold Amount,  reduced by  tax savings  of 34%,  divided by  the
    number of outstanding shares of Seller Common Stock.
 
    SECTION  6.02  EFFECT OF  TERMINATION.  In the  event of termination of this
Agreement by either  the Purchaser or  the Seller as  provided in Section  6.01,
this Agreement shall forthwith become void and have no effect and there shall be
no  liability on the part of any party hereto or to their respective officers or
directors except  that  (i) Sections  4.04(b),  4.04(c), 8.06  and  8.07,  shall
survive  any termination of this Agreement, and (ii) notwithstanding anything to
the contrary contained in this Agreement, no party shall be relieved or released
from any  liabilities  or damages  arising  out of  its  willful breach  of  any
provision of this Agreement.
 
    SECTION  6.03  THIRD PARTY  TERMINATION.  In recognition  of the efforts and
expenses  of,  and  other  opportunities   foregone  by,  the  Purchaser   while
structuring  the Merger,  the parties  agree that  the Seller  shall pay  to the
Purchaser a  termination fee  of $600,000  in cash  (the "Termination  Fee")  on
demand  if, during a period  of eighteen (18) months  after the date hereof, the
Merger has not been completed and any of the foregoing occurs:
 
       (a) Any person other than the Purchaser or an affiliate of the  Purchaser
           acquires  beneficial ownership of 50% or more of the then outstanding
    Seller Common Stock;
 
       (b) The Seller,  without having  received the  Purchaser's prior  written
           consent,  enters  into  an  agreement  to  engage  in  an Acquisition
    Transaction (as  defined  below) with  any  person (the  term  "person"  for
    purposes  of this Agreement having the  meaning assigned thereto in Sections
    3(a)(9) and  13(d)(3) of  the Exchange  Act and  the rules  and  regulations
    thereunder)  other  than the  Purchaser or  any of  its subsidiaries  or the
    Seller's Board of Directors recommends  that the shareholders of the  Seller
    approve or accept any Acquisition Transaction with any person other than the
    Purchaser  or  any  of its  subsidiaries.  For purposes  of  this Agreement,
    "Acquisition Transaction" shall mean (x)  a merger or consolidation, or  any
    similar  transaction, involving the  Seller, (y) a  purchase, lease or other
    acquisition of all or substantially all of the assets of the Seller or (z) a
    purchase or other  acquisition (including by  way of merger,  consolidation,
    share  exchange or otherwise) of securities  representing 50% or more of the
    voting power of the Seller; provided that the term "Acquisition Transaction"
    does not include  any internal  merger or consolidation  involving only  the
    Seller and/or its Subsidiaries; or
 
       (c) If a BONA FIDE proposal is made by a third party to the Seller or its
           shareholders  to engage in an  Acquisition Transaction and after such
    proposal is made any of the following events occurs: the Seller breaches any
    covenant or obligation  contained in  the Agreement  which would  materially
    impair  Seller's ability to  consummate the Merger  and such breach entitles
    the Purchaser to terminate  this Agreement; the  Shareholder Meeting is  not
    held or is canceled prior to termination of this Agreement for reasons other
    than  the  fault  of  the  Purchaser; or  the  Seller's  Board  of Directors
    withdraws  or  modifies   in  a   manner  adverse  to   the  Purchaser   the
    recommendation  of  the Seller's  Board of  Directors  with respect  to this
    Agreement.
 
    Notwithstanding the foregoing, the Seller shall  not be obligated to pay  to
the  Purchaser  the  Termination  Fee  if  the  Seller  validly  terminates this
Agreement pursuant to Section 6.01(b) or, prior to the Termination Fee  becoming
payable,  the Seller terminates this Agreement  pursuant to Section 6.01(c), (d)
or (f).

    SECTION 6.04   SPECIFIC ENFORCEABILITY.   The parties  recognize and  hereby
acknowledge  that it is  impossible to measure  in money the  damages that would
result to a party by reason of the failure of the other party to perform any  of
the  obligations imposed on it  by this Agreement and  that in any event damages
would be an inadequate remedy in  this instance. Accordingly, if a party  should
institute an action or proceeding seeking specific enforcement of the provisions
hereof, the other party hereby waives the claim or defense that the party making
the  claim has an adequate remedy at law  and hereby agrees not to assert in any
such action or proceeding the claim or defense that such a remedy at law  exists
and  shall waive or not  assert any requirement to  post bond in connection with
seeking specific performance.

hereto,  by or pursuant to action taken by their respective boards of directors,

                       [HOVDE FINANCIAL, INC. LETTERHEAD]
 
July 26, 1996
 
Board of Directors
Financial Security Corp.
1209 N. Milwaukee Avenue
Chicago, IL 60622-2294
 
Members of the Board:
 
    Financial Security Corp. ("Financial Security"), a Delaware corporation, and
Pinnacle  Banc Group, Inc.  ("Pinnacle"), an Illinois  corporation, have entered
into an Agreement  and Plan of  Merger (the "Agreement")  dated April 22,  1996,
pursuant  to  which  Financial  Security  will  merge  with  and  into  Pinnacle
(the"Merger"). As is set  forth in the  Agreement at the  effective time of  the
Merger,  each of the outstanding shares of Financial Security Corp. common stock
("Financial Security Common Stock") will be converted into and have the right to
receive, as determined pursuant to Section 1.02, and subject to Section 1.03(f),
of the Agreement  (the "Merger  Consideration"), one  of the  following: (i)  an
amount  in cash equal to $28.50 (the "Cash Distribution"); or (ii) 0.8803 shares
of Pinnacle common stock  ("Pinnacle Common Stock")  (the "Exchange Ratio");  or
(iii)  an amount in  cash equal to 30%  of the Cash Distribution  and 70% of the
Exchange Ratio (the "Combined Distribution"). In connection therewith, you  have
requested our opinion as to the fairness, from a financial point of view, of the
Merger Consideration to the shareholders of Financial Security.
 
    Hovde  Financial, Inc. ("Hovde") specializes in providing investment banking
and financial advisory services to commercial bank and thrift institutions.  Our
principals  are  experienced  in  the  independent  valuation  of  securities in
connection with negotiated underwritings, subscription and community  offerings,
private  placements, merger and  acquisition transactions and recapitalizations.
We are familiar with Financial Security,  having acted as its financial  advisor
in  connection with, and having participated in the negotiations leading to, the
Agreement.
 
    We were retained  by Financial Security  to act as  its exclusive  financial
advisor  with respect to a review of Financial Security's strategic alternatives
and the possible sale, merger, consolidation, or other business combination,  in
one  or a series of  transactions, involving all or  a substantial amount of the
business, securities or assets of Financial Security. We have received and  will
receive  compensation from Financial Security in connection with our services, a
significant portion of which is contingent upon the consummation of the  Merger.
At  your  direction, we  solicited  the interest  of  third parties  regarding a
possible business  combination with  Financial Security.  The Agreement  is  the
result of this solicitation.
 
    During  the  course of  our engagement,  we  reviewed and  analyzed material
bearing upon the financial  and operating conditions  of Financial Security  and
Pinnacle  and  material prepared  in connection  with the  proposed transaction,
including the following: the  Agreement; certain publicly available  information
concerning Financial Security and Pinacle, including Financial Security's annual
report  to shareholders and Form  10-K for the year  ended December 31, 1995 and
quarterly financial information  through March 31,  1996, and Pinnacle's  annual
report  to shareholders and Form  10-K for the year  ended December 31, 1995 and
quarterly financial  information through  March 31,  1996; the  terms of  recent
merger  and  acquisition  transactions  involving  thrifts  and  thrift  holding
companies that  we considered  relevant; historical  market prices  and  trading
volumes  for  Financial Security  Common Stock  and  Pinnacle Common  Stock; and
financial and other information provided to  us by the managements of  Financial
Security and Pinnacle.
 
                                      II-1
<PAGE>
    In  addition,  we  have  conducted  meetings  with  members  of  the  senior
management of Financial Security and Pinnacle  for the purpose of reviewing  the
future  prospects of Financial Security and  Pinnacle. We also evaluated the pro
forma ownership of  Pinnacle Common Stock  by Financial Security's  shareholders
relative   to  the  pro  forma  contribution  of  Financial  Security's  assets,
liabilities, equity and earnings  to the pro forma  company, and conducted  such
other  studies, analyses and examinations as we deemed appropriate. We also took
into account our assessment of general economic, market and financial conditions
and our experience in other transactions, as  well as our knowledge of the  bank
and thrift industries and our general experience in securities valuations.
 
    In   rendering   this  opinion,   we   have  assumed,   without  independent
verification,  the  accuracy  and  completeness  of  the  financial  and   other
information  and representations  contained in the  materials provided  to us by
Financial Security and Pinnacle and  in the discussions with Financial  Security
and  Pinnacle management. We did not independently verify and have relied on and
assumed that the aggregate allowances for  loan losses set forth in the  balance
sheets  of  each of  Financial  Security and  Pinnacle  at March  31,  1996 were
adequate to cover such losses and complied fully with applicable law, regulatory
policy and sound banking practices as of the date of such financial  statements.
We  were not retained to and did not conduct a physical inspection of any of the
properties or facilities of Financial Security or Pinnacle, nor did we make  any
independent  evaluation or appraisal of the  assets, liabilities or prospects of
Financial Security or Pinnacle, nor were  we furnished with any such  evaluation
or  appraisal, and  we were not  retained to  and did not  review any individual
credit files.
 
    We have assumed that the Merger is, and will be, in compliance with all laws
and regulations  that are  applicable  to Financial  Security and  Pinnacle.  In
rendering  this opinion, we have been advised by Financial Security and Pinnacle
and we have assumed that  there are no factors  that would impede any  necessary
regulatory  or governmental approval for the  Merger and we have further assumed
that in  the  course of  obtaining  the necessary  regulatory  and  governmental
approvals,  no  restriction  will  be  imposed  on  Pinnacle  or  the  surviving
corporation that  would  have a  material  adverse  effect on  Pinnacle  or  the
contemplated  benefits of the Merger. We have  also assumed that there would not
occur any change in the applicable law or regulation that would cause a material
adverse change  in the  prospects or  operations of  Pinnacle or  the  surviving
corporation after the Merger.
 
    Our  opinion is based  solely upon the  information available to  us and the
economic, market and other  circumstances as they exist  as of the date  hereof.
Events  occurring and information  that becomes available  after the date hereof
could materially  affect the  assumptions and  analyses used  in preparing  this
opinion.  We have not undertaken to reaffirm or revise this opinion or otherwise
comment upon any events  occurring or information  that becomes available  after
the date hereof.
 
    We are not expressing any opinion herein as to the prices at which shares of
Pinnacle Common Stock issued in the Merger may trade if and when they are issued
or  at any future time, nor does  our opinion constitute a recommendation to any
holder of Financial Security Common Stock as to how such holder should vote with
respect to the Agreements at any meeting of holders of Financial Security Common
Stock.
 
    This letter  is solely  for the  information of  the Board  of Directors  of
Financial  Security  and is  not  to be  used,  circulated, quoted  or otherwise
referred to for any other  purpose, nor is it to  be filed with, included in  or
referred  to in whole or in part  in any registration statement, proxy statement
or any other document, except in each case in accordance with our prior  written
consent  which shall  not be unreasonably  withheld; provided,  however, that we
hereby consent to the inclusion and reference to this letter in any registration
statement, proxy statement, information statement or tender offer document to be
delivered to the holders of Financial  Security Common Stock in connection  with
the  Merger if  and only  if this  letter is  quoted in  full or  attached as an
exhibit to such document  and this letter  has not been  withdrawn prior to  the
date of such document.

    Subject  to the foregoing and based on our experience as investment bankers,
our activities and  assumptions as described  above, and other  factors we  have
deemed  relevant, we are  of the opinion as  of the date  hereof that the Merger
Consideration is fair, from  a financial point of  view, to the shareholders  of
Financial Security.
 
                                          Sincerely,

                SECTION 262 OF DELAWARE GENERAL CORPORATION LAW
 
    SECTION262   APPRAISAL RIGHTS. -- (a)   Any stockholders of a corporation of
this State who  holds shares  of stock on  the date  of the making  of a  demand
pursuant  to subsection  (d) of  this section with  respect to  such shares, who
continuously holds  such shares  through the  effective date  of the  merger  or
consolidation,  who has otherwise  complied with subsection  (d) of this section
and who has neither voted in favor of the merger or consolidation nor  consented
thereto  in writing pursuant to Section228 of this title shall be entitled to an
appraisal by the  Court of Chancery  of the fair  value of his  shares of  stock
under the circumstances described in subsections (b) and (c) of this section. As
used  in this section, the word "stockholders" means a holder of record of stock
in a stock corporation and  also a member of  record of a nonstock  corporation;
the words "stock" and "share" mean and include what is ordinarily meant by those
words  and also  membership or  membership interest  of a  member of  a nonstock
corporation; and  the  words  "depository  receipt"  mean  a  receipt  or  other
instrument  issued  by a  depository  representing an  interest  in one  or more
shares, or fractions thereof, solely of  stock of a corporation, which stock  is
deposited with the depository.
 
    (b)  Appraisal rights  shall be  available for  the shares  of any  class or
series of stock of a constituent corporation in a merger or consolidation to  be
effected  pursuant  to  Section251 (other  than  a merger  effected  pursuant to
subsection (g) of Section 251), 252, 254, 257, 258, 263 or 264 of this title:
 
    (1) Provided, however, that no appraisal rights under this section shall  be
available  for  the shares  of any  class or  series of  stock, which  stock, or
depository receipts in respect  thereof, at the record  date fixed to  determine
the  stockholders entitled to  receive notice of  and to vote  at the meeting of
stockholders to act upon the agreement  of merger or consolidation, were  either
(i)  listed on a national securities exchange or designated as a national market
system security on an interdealer  quotation system by the National  Association
of  Securities Dealers, Inc. or (ii) held  of record by more than 2,000 holders;
and further provided that no appraisal rights shall be available for any  shares
of stock of the constituent corporation surviving a merger if the merger did not
require for its approval the vote of the holders of the surviving corporation as
provided in (1)subsection (f) of Section251 of this title.
 
    (2) Notwithstanding paragraph (1) of this subsection, appraisal rights under
this  section shall be available for the shares  of any class or series of stock
of a constituent corporation if the holders thereof are required by the terms of
an agreement of merger or consolidation pursuant to SectionSection251, 252, 254,
257, 258, 263 and 264 of this title to accept for such stock anything except:
 
    a.  Shares  of stock  of the corporation  surviving or  resulting from  such
merger or consolidation, or depository receipts in respect thereof;
 
    b.   Shares  of stock  of any other  corporation, or  depository receipts in
respect thereof, which shares of stock  or depository receipts at the  effective
date  of  the  merger or  consolidation  will  be either  listed  on  a national
securities exchange or  designated as a  national market system  security on  an
interdealer  quotation system by the National Association of Securities Dealers,
Inc. or held of record by more than 2,000 stockholders;
 
    c.  Cash  in lieu  of fractional  shares or  fractional depository  receipts
described in the foregoing subparagraphs a. and b. of this paragraph; or
 
    d.   Any combination of the shares of stock, depository receipts and cash in
lieu of  fraction shares  or  fractional depository  receipts described  in  the
foregoing subparagraphs a., b. and c. of this paragraph.
 
    (3) In the event all of the stock of a subsidiary Delaware corporation party
to  a merger effected under Section253 of this  title is not owned by the parent
corporation immediately prior to the merger, appraisal rights shall be available
for the shares of the subsidiary Delaware corporation.
 
                                     III-1
<PAGE>
    (c) Any corporation  may provide  in its certificate  of incorporation  that
appraisal  rights under this  section shall be  available for the  shares of any
class or series of its stock as a  result of an amendment to its certificate  of
incorporation,  any  merger  or  consolidation in  which  the  corporation  is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a  provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
    (d) Appraisal rights shall be perfected as follows:
 
    (1)  If a  proposed merger or  consolidation for which  appraisal rights are
provided under this  section is to  be submitted  for approval at  a meeting  of
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with  respect to  shares for  which appraisal  rights are  available pursuant to
subsections (b) and (c)  hereof that appraisal rights  are available for any  or
all  of the shares  of the constituent  corporations, and shall  include in such
notice a copy of this section. Each stockholder electing to demand the appraisal
of his shares shall deliver to the corporation, before the taking of the vote on
the merger or consolidation, a written demand for appraisal of his shares.  Such
demand  will  be sufficient  if  it reasonably  informs  the corporation  of the
identity of the stockholder and that  the stockholder intends thereby to  demand
the appraisal of his shares. A proxy or vote against the merger or consolidation
shall  not constitute such a demand. A  stockholder electing to take such action
must do so by a separate written demand as herein provided. Within 10 days after
the effective date of such merger  or consolidation, the surviving or  resulting
corporation  shall notify each  stockholder of each  constituent corporation who
has complied with this subsection and has not voted in favor of or consented  to
the  merger or consolidation  of the date  that the merger  or consolidation has
become effective; or
 
    (2) If the merger  or consolidation was approved  pursuant to Section228  or
253  of this  title, the surviving  or resulting corporation,  either before the
effective date of  the merger  or consolidation  or within  10 days  thereafter,
shall  notify  each of  the  stockholders entitled  to  appraisal rights  of the
effective date of  the merger  or consolidation  and that  appraisal rights  are
available for any or all of the shares of the constituent corporation, and shall
include  in such  notice a  copy of this  section. The  notice shall  be sent by
certified or  registered  mail,  return  receipt  requested,  addressed  to  the
stockholder  at his address as it appears on the records of the corporation. Any
stockholder entitled to appraisal rights may,  within 20 days after the date  of
mailing  of  the  notice, demand  in  writing  from the  surviving  or resulting
corporation the appraisal of  his shares. Such demand  will be sufficient if  it
reasonably  informs the corporation of the  identity of the stockholder and that
the stockholder intends thereby to demand the appraisal of his shares.
 
    (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied  with
subsections  (a)  and (d)  hereof  and who  is  otherwise entitled  to appraisal
rights, may file a petition in  the Court of Chancery demanding a  determination
of  the  value  of  the  stock of  all  such  stockholders.  Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger  or
consolidation,  any stockholder shall have the  right to withdraw his demand for
appraisal and to  accept the  terms offered  upon the  merger or  consolidation.
Within  120 days after  the effective date  of the merger  or consolidation, any
stockholder who has complied  with the requirements of  subsections (a) and  (d)
hereof,  upon written request, shall be entitled to receive from the corporation
surviving the merger  or resulting  from the consolidation  a statement  setting
forth  the  aggregate number  of  shares not  voted in  favor  of the  merger or
consolidation and with respect to which demands for appraisal have been received
and the aggregate number of holders of such shares. Such written statement shall
be mailed to the stockholder within 10 days after his written request for such a
statement is received  by the surviving  or resulting corporation  or within  10
days  after expiration of the period for delivery of demands for appraisal under
subsection (d) hereof, whichever is later.
 
                                     III-2
<PAGE>
    (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the  surviving or resulting corporation, which  shall
within 20 days after such service file in the office of the Register in Chancery
in  which the petition was  filed a duly verified  list containing the names and
addresses of all  stockholders who have  demanded payment for  their shares  and
with  whom agreements as to  the value of their shares  have not been reached by
the surviving or resulting  corporation. If the petition  shall be filed by  the
surviving  or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court,  shall
give  notice of  the time and  place fixed for  the hearing of  such petition by
registered or certified mail  to the surviving or  resulting corporation and  to
the  stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by 1 or more publications at least 1 week before the day  of
the  hearing, in  a newspaper  of general circulation  published in  the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail  and by publication shall be  approved by the Court,  and
the costs thereof shall be borne by the surviving or resulting corporation.
 
    (g)  At  the  hearing  on  such  petition,  the  Court  shall  determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court  may require the stockholders  who have demanded  an
appraisal  for their  shares and who  hold stock represented  by certificates to
submit their certificates  of stock  to the  Register in  Chancery for  notation
thereon  of the  pendency of the  appraisal proceedings; and  if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
    (h) After determining the stockholders  entitled to an appraisal, the  Court
shall appraise the shares, determining their fair value exclusive of any element
of  value  arising  from the  accomplishment  or  expectation of  the  merger or
consolidation, together with a fair  rate of interest, if  any, to be paid  upon
the  amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate  of
interest  which the surviving or resulting corporation  would have had to pay to
borrow money during  the pendency  of the  proceeding. Upon  application by  the
surviving or resulting corporation or by any stockholder entitled to participate
in  the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal  prior
to  the final  determination of  the stockholder  entitled to  an appraisal. Any
stockholder whose name appears on the  list filed by the surviving or  resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates  of stock  to the  Register in Chancery,  if such  is required, may
participate fully in all proceedings until  it is finally determined that he  is
not entitled to appraisal rights under this section.
 
    (i)  The Court  shall direct the  payment of  the fair value  of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the  Court
may  direct. Payment shall be  so made to each such  stockholder, in the case of
holders of uncertificated  stock forthwith, and  the case of  holders of  shares
represented  by  certificates  upon  the surrender  to  the  corporation  of the
certificates representing  such stock.  The Court's  decree may  be enforced  as
other  decrees in the Court of Chancery  may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
    (j)  The costs of  the proceeding may be determined  by the Court and  taxed
upon  the  parties  as the  Court  deems  equitable in  the  circumstances. Upon
application of  a stockholder,  the Court  may order  all or  a portion  of  the
expenses   incurred  by  any  stockholder   in  connection  with  the  appraisal
proceeding, including, without  limitation, reasonable attorney's  fees and  the
fees  and expenses of experts,  to be charged pro rata  against the value of all
the shares entitled to an appraisal.
 
    (k) From and  after the effective  date of the  merger or consolidation,  no
stockholder  who has demanded his appraisal rights as provided in subsection (d)
of this section  shall be  entitled to  vote such stock  for any  purpose or  to
receive  payment  of  dividends  or other  distributions  on  the  stock (except
dividends or other  distributions payable to  stockholders of record  at a  date
which is prior to
 
                                     III-3
<PAGE>
the  effective date of the merger  or consolidation); provided, however, that if
no petition  for  an  appraisal shall  be  filed  within the  time  provided  in
subsection  (e) of  this section,  or if such  stockholder shall  deliver to the
surviving or resulting  corporation a written  withdrawal of his  demand for  an
appraisal  and an  acceptance of the  merger or consolidation,  either within 60
days after the  effective date  of the merger  or consolidation  as provided  in
subsection  (e) of this section  or thereafter with the  written approval of the
corporation, then the  right of such  stockholder to an  appraisal shall  cease,
Notwithstanding  the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court,  and
such approval may be conditioned upon such terms as the Court deems just.
 
    (l) The shares of the surviving or resulting corporation to which the shares
of  such objecting stockholders  would have been converted  had they assented to
the merger or  consolidation shall have  the status of  authorized and  unissued
shares  of the surviving or resulting corporation.  (Last amended by Ch. 299, L.
'95, 2-1-96.)

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section  8.75 of the Illinois Business  Corporation Act of 1983, as amended,
grants to  each corporation  the  power to  indemnify its  directors,  officers,
employees  and agents against expenses  incurred in certain proceedings provided
they acted in good faith and in a  manner they reasonably believed to be in,  or
not  opposed to the best interests of the corporation and provided that they are
not adjudged to  be liable for  negligence or misconduct  in the performance  of
their  duty  to  the  corporation. This  statute  provides,  however,  that this
indemnification should  not be  deemed exclusive  of any  other  indemnification
rights provided by the by-laws, agreement, vote of stockholders or disinterested
directors  or otherwise. Article VII of the By-laws of Pinnacle Banc Group, Inc.
("Pinnacle") sets forth provisions which define the indemnification available to
Directors and Officers of Pinnacle. Article VII provides as follows:
 
                                INDEMNIFICATION
 
    SECTION 1.  To  the extent permitted  by Illinois law from  time to time  in
effect  and subject to the provisions of Section 2 of this Article, the Board of
Directors of the corporation shall indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or  proceeding,  whether  civil, criminal,  administrative  or  investigate
(whether  or not by  or in the right  of the corporation) by  reason of the fact
that such  person is  or  was a  director, officer,  employee  or agent  of  the
corporation  or is or was serving at the request of the agent of the corporation
as a  director, officer,  employee or  agent of  the corporation  or is  or  was
serving  at the request of the agent of the corporation, or is or was serving at
the request of  the corporation  as a director,  officer, employee  or agent  of
another  corporation,  partnership, joint  venture,  trust or  other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts  paid
in  settlement actually  and reasonably incurred  by him in  connection with any
such action, suit or  proceeding if he acted  in good faith and  in a manner  he
reasonably  believed  to be  in  or not  opposed to  the  best interests  of the
corporation, and, with  respect to  any criminal  action or  proceeding, had  no
reasonable  cause to  believe his conduct  was unlawful. The  termination of any
action, suit or proceeding by judgment, order, settlement, conviction, of upon a
plea of  nolo contendere  or its  equivalent,  shall not,  of itself,  create  a
presumption  that the person did not act in  good faith and in a manner which he
reasonably believed  to be  in  or not  opposed to  the  best interests  of  the
corporation,  and  with  respect  to  any  criminal  action  or  proceeding, had
reasonable cause to believe that his conduct was unlawful.
 
    SECTION 2.   Any indemnification  under Section  1 of  this Article  (unless
ordered  by  a court)  shall  be made  by  the Board  of  Directors only  upon a
determination in  the  specific  case  that  indemnification  of  the  director,
officer, employee or agent is proper in the circumstances because he has met the
applicable  standard of conduct set forth  in said Section 1. Such determination
shall be made  (a) by  the Board of  Directors by  a majority vote  of a  quorum
consisting of directors who were not parties to such action, suit or proceeding,
or  (b) if such quorum is not obtainable, or, even if obtainable and a quorum of

ITEM 22.  UNDERTAKINGS.
 
    The  undersigned  registrant  hereby   undertakes  that,  for  purposes   of
determining  any liability under the Securities Act  of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the  Securities
Exchange  Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
 
                                      II-2
<PAGE>
1934) that is incorporated by reference  in the registration statement shall  be
deemed  to be  a new registration  statement relating to  the securities offered
therein, and the offering of such securities at that time shall be deemed to  be
the initial BONA FIDE offering thereof.
 
    The  Registrant  hereby  undertakes as  follows:  that prior  to  any public
reoffering of the securities  registered hereunder through  use of a  prospectus
which  is a part of  this registration statement, by any  person or party who is
deemed to  be an  underwriter within  the  meaning of  Rule 145(c),  the  issuer
undertakes  that such reoffering prospectus  will contain the information called
for by the applicable  registration form with respect  to reofferings by  person
who may be deemed underwriters, in addition to the information called for by the
other items for the applicable form.
 
    The  Registrant undertakes that every prospectus  (i) that is filed pursuant
to the  paragraph immediately  preceding,  or (ii)  that  purports to  meet  the
requirements  of Section 10(a)(3) of  the Securities Act of  1933 and is used in
connection with an offering of securities subject to Rule 415, will be filed  as
a  part of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act  of 1933, each such  post-effective amendment shall  be
deemed  to be  a new registration  statement relating to  the securities offered
therein, and the offering of such securities at that time shall be deemed to  be
the bona fide offering thereof.
 
    Insofar  as indemnification for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
Registrant  pursuant to the  foregoing provisions, or  otherwise, the Registrant
has been advised that in the  opinion of the Securities and Exchange  Commission
such indemnification is against public policy as expressed in the Securities Act
of  1933  and  is, therefore,  unenforceable.  In  the event  that  a  claim for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant  of expenses incurred  or paid by a  director, officer or controlling
person of  the Registrant  in the  successful  defense of  any action,  suit  or
proceeding)  is  asserted by  such director,  officer  or controlling  person in
connection with the securities being registered, the Registrant will, unless  in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to  a  court  of  appropriate  jurisdiction  the  question  whether such
indemnification by it is  against public policy as  expressed in the  Securities
Act of 1933 and will be governed by the final adjudication of such issue.
 
    The  undersigned  Registrant hereby  undertakes to  respond to  requests for
information that is incorporated  by reference into  the prospectus pursuant  to
Items  4, 10(b), 11  or 13 of this  form, within one business  day of receipt of
such request, and  to send  the incorporated documents  by first  class mail  or
other  equally prompt  means. This  includes information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
    The undersigned  Registrant  hereby  undertakes  to supply  by  means  of  a
post-effective  amendment  all  information concerning  a  transaction,  and the
company being  acquired  involved therein,  that  was  not the  subject  of  and
included in the registration statement when it became effective.

    Re:  Pinnacle Banc Group, Inc.
       Registration Statement on Form S-4
       -------------------------------------------
 
Ladies and Gentlemen:
 
    We  have acted as special counsel to  Pinnacle Banc Group, Inc., an Illinois
corporation  (the  "Company"),  in  connection  with  the  preparation  of   the
above-referenced   Registration  Statement   on  Form   S-4  (the  "Registration
Statement"), to  be  filed by  the  Company  with the  Securities  and  Exchange
Commission  (the "Commission")  on the  date hereof.  The Registration Statement
relates to the registration  under the Securities Act  of 1933, as amended  (the
"1933  Act"), of 1,456,362 shares of the Company's Common Stock, $4.69 par value
per share  (the "Shares"),  which may  be exchanged  and issued  by the  Company
pursuant  to the  terms and  conditions of  that certain  Agreement and  Plan of
Merger, dated as of  April 22, 1996,  by and between  the Company and  Financial
Security Corp. (the "Merger Agreement").
 
    In  connection with  this opinion,  we have  examined and  are familiar with
originals or copies, certified or  otherwise identified to our satisfaction,  of
(i)  the Articles of Incorporation and the  By-Laws of the Company, (ii) certain
resolutions of the Board of Directors of the Company relating to the offering of
the Shares, (iii) the Registration Statement and (iv) such other documents as we
have deemed necessary or appropriate as bases for the opinions set forth  below.
In  such examination,  we have  assumed the  genuineness of  all signatures, the
legal capacity of natural persons,  the authenticity of all documents  submitted
to  us  as originals,  the  conformity to  original  documents of  all documents
submitted to us as certified or  photostatic copies and the authenticity of  the
originals  of such latter  documents. As to  any facts material  to this opinion
which we  did  not  independently  establish or  verify,  we  have  relied  upon
statements  and  representations of  officers and  other representatives  of the
Company and others.
 
    Members of our  firm are admitted  to the practice  of law in  the State  of
Illinois, and we express no opinion as to the laws of any other jurisdiction.
 
    Based  upon and  subject to the  foregoing, we  are of the  opinion that the
Shares have been  duly and  validly authorized  and, when  issued and  delivered
pursuant  to the terms and conditions of  the Merger Agreement, will be duly and
validly issued, fully paid and nonassessable.
 
    This opinion is furnished to you solely for your benefit in connection  with
the  filing of  the Registration  Statement and is  not to  be used, circulated,
quoted or otherwise referred to for any other purpose without our prior  written
consent.  Notwithstanding the foregoing, we hereby consent to the filing of this
opinion with the  Commission as Exhibit  5.1 to the  Registration Statement.  We
also  consent to the reference to our  firm under the caption "Legal Matters" in
the Registration Statement. In giving this consent, we do not thereby admit that
we are  included in  the category  of persons  whose consent  is required  under
Section 7 of the Act or the rules and regulations of the Commission.
 
                                          Very truly yours,

    Re:  Federal Tax Consequences of the Merger of Financial Security Corp.
       with and into Pinnacle Banc Group, Inc.
 
To the Members of the Board:
 
    You  have  requested  an opinion  with  respect  to the  Federal  income tax
consequences of  the proposed  merger of  Financial Security  Corp., a  Delaware
corporation  ("Financial Security"), with and into Pinnacle Banc Group, Inc., an
Illinois corporation ("Pinnacle") (the "Merger"), pursuant to the Agreement  and
Plan of Reorganization dated as of April 22, 1996 which provides for a statutory
merger  under Illinois and Delaware law  between Financial Security and Pinnacle
(the "Plan of Reorganization").  Upon consummation of  the Merger, the  separate
existence  of Financial Security shall cease and Pinnacle will be the continuing
and surviving corporation.
 
    The proposed  transaction and  the  parties are  described  in the  Plan  of
Reorganization. We have made such inquiries and have examined such documents and
records  as  we have  deemed appropriate  for  the purpose  of this  opinion. In
rendering this opinion,  we have  received certain  standard representations  of
Pinnacle  and Financial Security  concerning Pinnacle and  Financial Security as
well as the transaction ("Representations"). These Representations are  required
to  be furnished prior  to the execution of  this letter and  again prior to the
closing of the Merger. We will rely upon the accuracy of the Representations  of
Pinnacle  and Financial  Security and  the statements  of fact  contained in the
examined documents,  particularly  the  Plan of  Reorganization.  We  have  also
assumed  the authenticity of  all signatures, the legal  capacity of all natural
persons and the conformity to the originals of all documents submitted to us  as
copies.  Each capitalized  term used herein,  unless otherwise  defined, has the
meaning set  forth in  the Plan  of  Reorganization. We  have assumed  that  the
transaction  will be  consummated strictly in  accordance with the  terms of the
Plan of Reorganization.
 
    The  Plan  of   Reorganization  (including   exhibits),  contains   detailed
descriptions of the parties to the Merger and the Merger itself. These documents
as well as the Representations to be provided by Pinnacle and Financial Security
are incorporated in this letter as part of the statement of the facts.
 
    In  order to effect  the Merger, each  share of the  common stock, par value
$0.01 per  share,  of Financial  Security  ("Financial Security  Common  Stock")
issued  and outstanding immediately prior to  the Effective Time (other than any
shares of Financial Security Common Stock  held by Financial Security or any  of
its  wholly-owned  subsidiaries,  or  by Pinnacle  or  any  of  its wholly-owned
subsidiaries, all  of which  shares  will be  cancelled) other  than  Dissenting
Shares,  shall be  converted into  the right  to receive  a combination  of cash
and/or shares of  Pinnacle Common  Stock. The combined  value of  this right  is
referred to as the "Merger Consideration."
<PAGE>
Board of Directors
July 26, 1996
Page 2
 
    Pursuant   to  the  terms   of  the  Plan   of  Reorganization,  the  Merger
Consideration shall be calculated such  that the aggregate Merger  Consideration
so determined consists of not more than 45% cash consideration and not less than
55%  stock  consideration  or  such  higher  percentage  of  stock consideration
necessary to qualify the Merger as a tax-free reorganization within the  meaning
of  section  368(a)  of the  Internal  Revenue  Code of  1986,  as  amended (the
"Code")). The stock portion of the Merger Consideration may be greater than  55%
and the cash portion may be less than 45% of the aggregate Merger Consideration.
Thus, under the Plan of Reorganization, the aggregate amount of cash that may be
received  by Financial Security shareholders in the merger may not exceed 45% of
the value of all  the formerly outstanding shares  of Financial Security  Common
Stock  issued and outstanding at the Effective  Time of the Merger. For purposes
of this limitation, shares of Financial Security Common stock exchanged for cash
or other property, surrendered by dissenters,  or exchanged for cash in lieu  of
fractional  shares, will  be treated  as outstanding  stock on  the date  of the
transaction.
 
                                    OPINION
 
    Based upon the facts set forth above and in the Plan of Reorganization,  the
Representations  discussed above,  and assuming  the the  Merger is  effected in
accordance with the  terms of the  Plan of Reorganization  between Pinnacle  and
Financial  Security  as well  as in  conformity with  applicable law,  rules and
regulations, and assuming that  Financial Security is  solvent, and taking  into
consideration  the limitations discussed in this opinion, it is our opinion that
under current federal income tax law:
 
    (1) The  proposed  Merger of  Financial  Security  and Pinnacle  will  be  a
       reorganization within the meaning of section 368(a) of the Code. Pinnacle
       and  Financial Security will each be a "party to a reorganization" within
       the meaning of section 368(b) of the Code.
 
    (2) No gain  or loss will  be recognized by  Pinnacle or Financial  Security
       upon  the exchange in  the Merger, pursuant  to the terms  of the Plan of
       Reorganization, of Pinnacle Common Stock  and cash for all the  Financial
       Security Common Stock as provided for in the Plan of Reorganization.
 
    (3)  No gain  or loss  will be recognized  by the  shareholders of Financial
       Security who receive shares of Pinnacle Common Stock in exchange for  all
       of  their shares of Financial Security Common Stock, except to the extent
       of any cash  received, including cash  received in lieu  of a  fractional
       share  of  Pinnacle Common  Stock. Gain,  if any,  will be  recognized by
       holders of the shares of Financial Security Common Stock who receive both
       Pinnacle Common Stock (including a fractional share interest) and cash in
       exchange for their Financial Security Common Stock, but not in excess  of
       the  amount  of cash  received. If  the  exchange has  the effect  of the
       distribution of a  dividend (determined with  the application of  section
       318(a)  of the Code), then the amount  of the gain recognized that is not
       in excess of  shareholder's ratable share  of undistributed earnings  and
       profits  will be treated as a  dividend. The determination of whether the
       exchange has the effect of a dividend will be made in accordance with the
       principles set forth in  COMMISSIONER V. CLARK, 489  U.S. 726 (1989).  No
       loss  will be  recognized on  the exchange  of Financial  Security Common
       Stock for Pinnacle Common Stock  (including a fractional share  interest,
       if any), and cash, as described in paragraph (2) above (section 354(a)(1)
       of the Code).
 
    (4) A Financial Security stockholder who receives cash in the Merger in lieu
       of  a fractional share of Pinnacle Common Stock will be treated as if the
       fractional share had  been received in  the Merger and  then redeemed  by
       Pinnacle  in return for the cash. The receipt of such cash will cause the
       recipient to  recognize capital  gain  or loss  equal to  the  difference
       between  the amount  of cash  received and  the portion  of such holder's
       adjusted tax basis in  the shares of Pinnacle  Common Stock allocable  to
       the fractional share.

    (5)  The  basis of  the Pinnacle  Common Stock  received by  shareholders of
       Financial Security in the  Merger will be  the same as  the basis of  the
       Financial   Security  Common  Stock  surrendered  in  exchange  therefor,
       decreased by the amount of any cash received, and increased by the amount
       of any gain recognized in the exchange.
 
    (6) The  holding  period  of  the Pinnacle  Common  Stock  received  by  the
       Financial  Security shareholders will  include the holding  period of the
       Financial Security Common Stock  surrendered therefor, provided that  the
       Financial  Security Common Stock was, in each instance, held as a capital
       asset in  the hands  of  the shareholder  of  Financial Security  at  the
       Effective Time.
 
    (7) The basis of the assets of Financial Security to be received by Pinnacle
       will  be the same as the basis of  those assets in the hands of Financial
       Security immediately prior to the Merger.
 
    (8) The holding period of the assets of Financial Security to be received by
       Pinnacle will include the holding period of those assets in the hands  of
       Financial Security immediately prior to the Merger.
 
                             LIMITATIONS OF OPINION

Code including  applicable  regulations  thereunder  and  current  judicial  and
administrative  authority.  Any  future  amendment  to  the  Code  or applicable

        FORM OF LETTER OF UNDERSTANDING BETWEEN EXECUTIVES AND PINNACLE*

    Re: Letter of Understanding
 
Dear Mr. Augustine:
 
    As  you know,  Pinnacle Banc  Group, Inc.  ("Pinnacle") has  entered into an
Agreement and Plan of Merger dated April 22, 1996 (the "Merger Agreement")  with
Financial   Security  Corp.  (the  "Company")   with  respect  to  the  proposed
transaction  whereby  the  Company  will  merge  with  and  into  Pinnacle  (the
"Merger").  Pursuant to Section 4.02(c) of  the Merger Agreement, the employment
agreement between the Company and you  will be honored, unless you and  Pinnacle
otherwise  mutually agree  to another  arrangement. Pinnacle  believes that your
continued service as a  consultant will assist in  fully preserving the  ongoing
business  operations of the  Company following the  Merger. Capitalized terms in
this Letter of Understanding (the "Letter") will have the same meaning as in the
Merger Agreement and the Employment Agreement.
 
    By signing this Letter you will  confirm your understanding of the terms  of
this Letter and agree to:
 
        (1)   execute prior to the Closing  Date, an amendment to the Employment
    Agreement to provide that, in lieu of the payment to be made under Section 6
    of the Employment Agreement, you will  receive a payment of an amount  equal
    to  One  Dollar ($1.00)  less than  the  least amount  that would  cause the
    benefits payable  to you  in  connection with  the  Merger to  constitute  a
    parachute  payment as defined in Section  280G(b)(2) of the Internal Revenue
    Code of 1986,  as amended  (the "New Change  in Control  Payment"). The  New
    Change  in Control Payment shall  not exceed $484,557. If  the Merger is not
    consummated prior to December  31, 1996, the New  Change in Control  Payment
    shall be subject to adjustment; and
 
        (2)   execute prior  to the Closing Date  a Consulting Agreement between
    Pinnacle  and  you  which  will  provide  for  the  performance  of  certain
    consulting  services in  consideration for  an amount  ("Consulting Amount")
    mutually agreed to by both parties to  be effective in the event you do  not
    become employed by Pinnacle in connection with the Merger.
 
    The  Company will obtain a  written opinion of a  public accountant that the
New Change in Control Payment taken together with the Consulting Amount and  any
other  payments made  to you by  Pinnacle or  the Company will  not constitute a
parachute payment  under Section  280G(b)(2) of  the Code.  The accounting  firm
shall  be a nationally  recognized firm and  mutually agreed to  by the Company,
Pinnacle and you. Pinnacle shall bear  the cost of acquiring such opinion.  Such
opinion will be addressed to the Company, Pinnacle and you.
- ------------------------
*    Similar agreements, albeit with  different change in control payments, were
    executed between Pinnacle Banc Group, Inc. and Messrs. Ivan F. Kovac,  Frank
    M. Swiderski and Patrick Hunt.

    The  Company will  obtain a  written appraisal  opinion from  a professional
valuation firm that the Consulting  Amount is reasonable consideration for  your
services  under the Consulting  Agreement. The valuation  firm shall be mutually
agreed to by  the Company, Pinnacle  and you.  Pinnacle shall bear  the cost  of
acquiring  such opinion. Such opinion will be addressed to the Company, Pinnacle
and you.
 
    Neither Pinnacle nor any of its  affiliates will bear any responsibility  to
you  in the  event that  excise taxes  are assessed  in connection  with the New
Change in Control Payment, the Consulting  Amount or any other payments made  to
you by Pinnacle or the Company.
 
    If  the  Merger is  not  effectuated, this  Letter  will terminate  upon the
termination of the Merger Agreement.
 
    Please acknowledge your acceptance  of this Letter and  its terms, and  your
agreement  to  amend  the  Employment  Agreement  and  enter  into  a consulting
agreement by signing in the place provided below and returning one copy of  this
Letter to Pinnacle.
 
                                          Very truly yours,
 
                                          Pinnacle Banc Group, Inc.

regarding the acquisition of Financial Security Corp. ("Financial Security")  by
Pinnacle  Banc Group, Inc. ("Pinnacle"), in Pinnacle's registration statement on
Form S-4 (the "Registration Statement") and  to the inclusion of the summary  of

                    ELECTION FORM FOR USE BY STOCKHOLDERS OF
                            FINANCIAL SECURITY CORP.
 
Harris Trust and Savings Bank
311 West Monroe Street
14th Floor West
Chicago, Illinois 60606
 
Dear Financial Security Corp. Stockholder:
 
    Pursuant  to the  terms of  the Agreement  and Plan  of Merger  (the "Merger
Agreement"), dated  as of  April 22,  1996, between  Pinnacle Bank  Group,  Inc.
("Pinnacle"),   and  Financial   Security  Corp.   ("Financial  Security"),  the
undersigned stockholder(s) of Financial Security elects to receive the following
category of consideration in conversion of his or her shares of common stock  of
Financial Security, par value $.01 per share ("Financial Security Common Stock")
upon consummation of the merger:
 
/ /  STOCK  ELECTION -- .8803  shares (the "Exchange  Ratio") of Pinnacle Common
     Stock, subject  to adjustment  dependent upon  the Pinnacle  Average  Stock
     Price as provided in the Merger Agreement (the "Stock Distribution");
 
/ /  CASH  ELECTION -- a cash payment in an  amount equal to $28.50 per share of
     Financial Security Common Stock (the "Cash Distribution"); or
 
/ /  COMBINED  ELECTION  --  an  amount  in  cash  equal  to  30%  of  the  Cash
     Distribution  and shares of Pinnacle Common Stock equal to 70% of the Stock
     Distribution.
 
    THE UNDERSIGNED ACKNOWLEDGES THAT THE DEADLINE FOR FILING THIS ELECTION FORM
WITH HARRIS TRUST AND SAVINGS BANK ("HARRIS") IS BY 5:00 P.M., CENTRAL TIME,  ON
SEPTEMBER  10,  1996,  THE DAY  PRIOR  TO THE  DATE  OF THE  SPECIAL  MEETING OF
STOCKHOLDERS OF FINANCIAL SECURITY CALLED TO  CONSIDER AND VOTE UPON THE  MERGER
AGREEMENT.
 
    PURSUANT  TO THE MERGER AGREEMENT, ANY  STOCKHOLDER WHO FAILS TO DELIVER THE
ELECTION FORM TO  HARRIS PROPERLY COMPLETED  AND EXECUTED BY  THE DEADLINE  WILL
RECEIVE THE STOCK DISTRIBUTION.
 
    The  undersigned acknowledges that the  consideration received in connection
with the Stock Distribution and the Combined Distribution is subject to possible
adjustment depending on  the Pinnacle  Average Stock  Price (as  defined in  the
Merger  Agreement)  prior to  the Effective  Time, and  as discussed  in greater
detail in the Joint Proxy Statement/ Prospectus.
 
    The undersigned further acknowledges  that the Cash  Election is subject  to
the  limitations  on the  issuance  of not  less than  the  number of  shares of
Pinnacle Common  Stock such  that the  aggregate consideration  received in  the
Merger  consists  of  at  a  minimum  55%  stock  consideration  or  such higher
percentage necessary  for  Muldoon,  Murphy &  Faucette,  counsel  to  Financial
Security,  to  render an  opinion that  the merger  qualifies as  a tax-deferred
reorganization for  those stockholders  who receive  shares of  Pinnacle  Common
Stock  in exchange for their shares of  Financial Security Common Stock. See the
accompanying  Joint  Proxy  Statement/Prospectus  --  "THE  MERGER  --  Election
Procedures"  for a description of the situations in which the Exchange Agent may
be required to reallocate  the consideration to be  paid to stockholders  making
the Cash Election.
 
    Prior  to 5:00  p.m., Central Time,  on September 10,  1996, the undersigned
may, at any time or from  time to time, change his  or her election by filing  a
new Election Form with Harris.
 
    FOR  INFORMATION  CONCERNING THE  SUBMISSION  OF THE  ELECTION  FORM, PLEASE
CONTACT HARRIS AT (312) 461-6001. STOCKHOLDERS WHO HAVE QUESTIONS REGARDING  THE
ELECTION  PROCESS,  AND/OR THE  TAX CONSEQUENCES  ASSOCIATED WITH  SUCH ELECTION
PROCESS, SHOULD  CONSULT,  AT  THEIR  OWN EXPENSE,  THEIR  OWN  TAX,  LEGAL  AND
INVESTMENT ADVISORS.
