EXHIBIT 2 - ANNUAL REPORT TO SECURITY HOLDERS

Letter to Shareholders
--------------------------------------------------------------------------------
 
Dear Shareholder:
 
Each year this letter serves as our forum to review Pinnacle's performance for
the past year as well as an opportunity to communicate our objectives for the
future. The recently completed year was one of mixed results from our viewpoint.
While the financial results were not up to Pinnacle's high performance standards
and the price of Pinnacle common shares declined, some significant strides were
made in achieving our stated objectives. An acquisition was completed bringing
total assets to in excess of $1 billion and improvement was made in Pinnacle's
core banking function including internally generated loan growth of 14% in 1996.
 
FINANCIAL PERFORMANCE
 
In last year's letter, we stated that while 1995 was a successful one for
Pinnacle from a numbers standpoint, 1996 would be much more challenging. We were
concerned that the relatively low rate environment coupled with Pinnacle's high
volume of U. S. Government securities and a relatively flat yield curve would
continue to put pressure on Pinnacle's net interest margin and earnings in the
near term. Unfortunately, we were correct. Net income for 1996 totalled
$7,127,000, or $1.05 per share, adjusted for the 3-for-2 stock split which was
effective on February 10, 1997, compared to net income of $12,493,000, or $1.89
per share, earned in 1995, a per share decrease of 44%. The return on average
equity for 1996 was 9.0% and the return on average assets amounted to 0.82%.
 
In fact, the relatively low rate environment was the primary reason for the
earnings decrease. Pinnacle's net interest margin declined to 3.51% in 1996 from
3.90% in 1995. Lower yields earned on U. S. Government securities, which made up
a significant portion of Pinnacle's balance sheet, and moderately higher deposit
costs resulting from the reallocation of funds by customers from savings and
money market deposits to time accounts, were contributors to the lower net
interest margin. In addition, net income was negatively impacted by the fact
that only $159,000 in net gains on the sale of securities were recorded in 1996
compared to $4,731,000 of gains booked in 1995.
 
Total assets were $1.05 billion at December 31, 1996, a 28% increase from the
same date of the previous year. Total loans were $525 million, up 70%, and total
deposits amounted to $878 million, a 23% increase. Equity capital totalled $101
million, an increase of 28%. Book value was $13.23 at December 31, 1996,
adjusted for the stock split. The increase in each of the balance sheet
categories was the result of the acquisition which was completed at the end of
the third quarter of 1996.
 
Pinnacle's common stock price did not fare well in 1996. The stock closed at
year-end 1996 at $18.83, adjusted for the stock split, versus a closing price of
$22.33 on December 31, 1995, a decline of 16%. This was especially disappointing
since the decline took place in a year in which significant gains were recorded
in the market in general and in bank stocks in particular. Our belief is that
the decrease was attributable to two factors. First, Pinnacle's earnings results
in 1996 were lower than historical levels. Second, an over supply of shares in
the marketplace during mid-year and the effect of the cash/stock allocation in
the acquisition completed in September limited the opportunity for any price
appreciation since supply outweighed demand.
 
MOMENTUM FOR THE FUTURE
 
The year's most significant accomplishment was the acquisition of Financial
Security Corp. and its wholly-owned subsidiary, Security Federal Savings and
Loan Association of Chicago, which was completed on September 30, 1996. The
acquisition added $213 million in year end assets to Pinnacle pushing the
company to over $1 billion in assets and accomplishing an objective that was
first stated in our 1994 annual report letter, and reaffirmed last year--to
reach $1 billion in assets by year-end 1996. As a result of the transaction, two
new locations were added to the Pinnacle franchise, one on the near northwest
side of Chicago and the other in north suburban Niles. The acquisition also made
some important additions to Pinnacle's management team and increased the
company's total loan to asset ratio to 50%, both key factors in future success
for Pinnacle. The acquisition was completed using a combination of cash and
stock, Pinnacle's first such transaction since 1989. It was our hope that the
issuance of stock to a new group of shareholders would increase the liquidity in
Pinnacle common shares and narrow the quoted spread between the bid and asked
side of the market. In fact, since the transaction, trading volume has increased
and the quoted spread has narrowed. An additional benefit of the acquisition was
the change to the NASDAQ National Market System from the Small Cap Market for
trading in Pinnacle common shares.
 
Pinnacle made some tangible strides in accomplishing another of its objectives.
A recurring theme in these annual letters has been the necessity to continue to
improve the core earnings of the banking function. Total loans increased 14%

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

in 1996, not including the effect of the acquisition. This marked the first time
since 1988 that Pinnacle has had any meaningful internal loan growth. We believe
this growth was the result of a stronger focus on the lending function, coupled
with marketing efforts including a business calling program. We feel we have
succeeded in a highly competitive lending environment by being a little more
aggressive on pricing while keeping our credit standards in tact.
 
We also made strides in making Pinnacle a more visible provider of financial
services. Hopefully, you have heard our radio advertising highlighting our home
equity product, small business lending, trust alternatives, or Pinnacle's newest
product which is PC Banking for banking at home by computer. We were able to
increase our financial service products per household in 1996, although we still
have plenty of room to go to meet our goals. We continue to complete the
integration of our banking centers through the merger of Pinnacle's thrift
subsidiaries into Pinnacle Bank. In addition, Pinnacle plans to open its first
new branch location by the end of the summer in a west suburban location. By the
end of the third quarter, Pinnacle will have thirteen locations in the Chicago
area at which any customer can transact business with an additional two
locations in the metropolitan area of the Quad-Cities, Illinois.
 
On the non-banking side of the performance ledger, Pinnacle's equity portfolio
of investments in other banks and thrifts continued to evolve into a major
earnings contributor for the future. At year-end 1996, the portfolio totalled
$28.2 million with $8.7 million in unrealized appreciation. An interesting way
to view this portfolio is that through these investments, Pinnacle holds an
additional $250 million in non-balance sheet banking assets as an alternative to
purchasing 100% of another financial institution. The plan is to use these
investments as a vehicle to supplement improving core bank earnings, thereby
achieving a high performance objective.
 
OUR OBJECTIVES
 
Our goals continue to remain the same as we have communicated in the past:
enhance shareholder value by effectively leveraging Pinnacle's equity base and
to achieve returns on equity and assets significantly in excess of peer group
performance. On the corporate side, we can accomplish these goals through
continued acquisitions and common share repurchases. As part of Pinnacle's
equity management program, a 6% increase in the dividend was announced in
January, 1997, the ninth consecutive annual increase since Pinnacle became a
publicly traded company in 1988; and a 3-for-2 stock split was effective in
February, 1997, the third such split since 1990. On the banking side, we will
continue our efforts to improve the core earnings of the bank and ensure that
responsive, quality service will differentiate Pinnacle banks from our
competitors.
 
The recently completed year is a perfect example of this necessity. In past
years, Pinnacle has relied for its success on non-core bank earnings--the
investment portfolio, tax planning strategies and other innovative programs
unrelated to traditional banking. These items can continue to play an important
role for Pinnacle. However, the core bank portion of earnings must be enhanced
in order to provide a more consistent earnings stream and to lessen the effect
of an interest rate environment which may not be favorable to Pinnacle's
investment portfolio as was the case in 1996.
 
In summary, while the financial numbers for 1996 relating to earnings and stock
price performance were not up to Pinnacle's corporate standards, the
acquisition, loan growth, marketing efforts, and equity portfolio made the year
an acceptable foundation for the future. Pinnacle's performance in the past has
been strong as evidenced by an average return on equity of 17.3% and a return on
assets of 1.62% for the nine year life of Pinnacle as a publicly traded company.
Pinnacle's performance in the future will hinge on our ability to accomplish the
aforementioned objectives and management is confident in its ability to do so.
 
We thank you for your continued support and assure you that maximizing
shareholder value remains our number one priority.
 
Sincerely,

/s/John J. Gleason, Jr.
 
John J. Gleason, Jr.
Vice Chairman and
 Chief Executive Officer

Notes to Consolidated Financial Statements
PINNACLE BANC GROUP, INC. and Subsidiaries
--------------------------------------------------------------------------------
 
      ALL DOLLARS IN THE FOLLOWING FOOTNOTES ARE IN THOUSANDS, EXCEPT PER SHARE
      AMOUNTS.
 
ACCOUNTING POLICIES:(1)
 
      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 and thrift 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:
 
CONSOLIDATION - (A)
 
          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"), Security
Federal Savings and Loan Association ("SF"), and Pinnacle Bank, FSB (formerly
Batavia Savings Bank) ("FSB"). 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.
 
STATEMENTS OF CASH FLOWS - (B)
 
          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 1996,
Financial Security ("FinSec") and its subsidiary, SF, were purchased for a
combination of stock and cash. The cash portion of the acquisition price was
$20,140; the non-cash portion of the acquisition consisted of 1,285,413
(adjusted for stock split, see Footnote 10) shares valued at $23,995. At the
date of purchase, the balance sheet of FinSec included cash and cash equivalents
of $1,090, resulting in a net cash position of $19,050. In 1995, Acorn Financial
Corp ("AFC") and its subsidiary bank, Suburban Trust & Savings Bank ("STSB") was
purchased by the Corporation and cash of $23,414 was paid for the acquisition.
At the date of purchase, the balance sheet of AFC included cash and cash
equivalents of $8,614 resulting in a net cash position of $14,800.
 
    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 1996, the amount was $6,022 for the acquisition of FinSec. In 1995,
this amount was $23,414 for the acquisition of AFC.
 
SECURITIES - (C)
 
          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, at
January 1, 1994.
 
          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.
 
LOANS - (D)
 
          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.
 
ALLOWANCE FOR LOAN LOSSES - (E)
 
          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.
 
PREMISES AND EQUIPMENT - (F)
 
          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.
 
OTHER REAL ESTATE - (G)
 
          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.
 
INCOME TAXES - (H)
 
          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.
 
          SFAS No. 109, "Accounting for Income Taxes", 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.
 
NEW ACCOUNTING PRONOUNCEMENTS - (I)
 
          LONG-LIVED ASSETS
 
          Effective January 1, 1996, Pinnacle adopted 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. If impairment is indicated,
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.

STOCK BASED COMPENSATION
 
          In October, 1995, SFAS No. 123, "Accounting for Stock Based
Compensation" was issued. This standard establishes accounting and reporting
standards for stock-based awards, such as stock options, granted in fiscal years
beginning after December 31, 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 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. The Corporation elected not to adopt the fair value method. See
Footnote 11.
 
TRANSFERS OF FINANCIAL ASSETS AND EXTINGUISHMENTS OF LIABILITIES
 
          In 1996, FASB issued Statement No. 125, "Accounting for Transfers and
Servicing of Financial Assets and Extinguishments of Liabilities" and Statement
No. 127, "Deferral of the Effective Date of Certain Provisions of SFAS Statement
No. 125". The statement addresses the parameters in which the transfers of
assets and extinguishment of liabilities are considered a sale and removed from
the balance sheet or recorded as secured borrowings. This statements affects the
Corporation through certain financial instruments such as loan participations or
repurchase agreements and whether the Corporation has relinquished total control
over the transfer of assets or extinguishment of liabilities. The effective date
of the standard was for fiscal years beginning after December 31, 1996. The
Corporation adopted SFAS No. 125 and SFAS No. 127 on January 1, 1997 and there
was no significant effect on its consolidated financial position or results of
operations.
 
ESTIMATES - (J)
 
          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.
 
ACQUISITIONS: (2)
 
      Effective September 30, 1996, Pinnacle completed the acquisition of FinSec
and its subsidiary, SF. The total purchase price was $44,756, common shares
issued were 1,285,413 (adjusted for stock split) valued at $23,995, and the
remainder was paid in cash. Funds utilized to pay for the cash portion of the
acquisition were obtained from funds on hand at Financial Security, a dividend
from SF, and borrowed from an unaffiliated bank.
 
      At the date of the purchase, FinSec was liquidated and SF will remain a
separate subsidiary of Pinnacle until January 31, 1997 at which time SF will be
merged with and into PB. As of the date of the purchase, FinSec had total assets
of approximately $250,000. Goodwill, based on management's estimates of fair
value of assets acquired and liabilities assumed, approximates $8,100 which is
being amortized on a straight-line basis over fifteen years. Fair value
appraisals, tax net operating loss carrybacks, and determination of termination
benefits are being updated and will be adjusted, if necessary, when completed.
Management does not anticipate material changes to the above goodwill amount.
 
      This transaction is being accounted for using the purchase method of
accounting and, accordingly, the excess of the aggregate purchase price over the
fair value of the net assets acquired consisted of goodwill. Because the
acquisition occurred at September 30, 1996, the income effect of SF is included
in Pinnacle's results of operations for the last three months of 1996.
 
      The following unaudited results of operations reflect the acquisition of
FinSec as if the acquisition had occurred at the beginning of 1995:

      On January 6, 1995, the Corporation completed the acquisition of AFC and
its subsidiary STSB. The purchase price was $23,414 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. Goodwill of approximately $13,000
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

      At December 31, 1996 and 1995, the Corporation had goodwill of $23,576 and
$17,047, respectively. Goodwill is stated net of accumulated amortization of
$19,158 and $17,466 at December 31, 1996 and 1995, 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, Bank of Silvis in 1989, BNB and The Henry County Bank in 1991, Batavia
Savings Bank in 1992, AFC in 1995, and FinSec in 1996. Goodwill is being
amortized on straight line and accelerated methods over periods of 10 years to
20 years. Amortization of goodwill amounted to $1,692 in 1996, $1,544 in 1995,
and $1,340 in 1994.
 
      Other intangibles consist of a deposit base intangible totalling $1,790
and $2,130 as of December 31, 1996 and 1995, 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 $1,619 and $1,278 at December 31, 1996 and 1995, respectively.
Amortization of the deposit base intangible, which is being amortized over an
estimated 10-year life, amounted to $341 in 1996, 1995, and 1994.
 
SECURITIES: (3)
      As discussed in Note 1, the Corporation adopted SFAS No. 115, effective
January 1, 1994. The amortized cost and the estimated fair value of the

      Proceeds from sales of debt securities during 1996 were $1,110,249. Gross
gains of $349 and gross losses of $190 were realized on those sales. Proceeds
from sales of debt securities during 1995 were $3,092,834. Gross gains of $4,279
and gross losses of $273 were realized on those sales.
 
      At December 31, 1996 and 1995, securities carried at approximately $31,468
and $29,477, 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, 1996
or 1995, which constituted an unusual credit risk for the Corporation.

      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 with
the exception of loans acquired from the acquisition of SF. Included in SF loan
portfolio are certain purchased and participated loans outside the Corporation's
defined customer markets. These loans totalled approximately $58,337 of the
total loan portfolio of the Corporation and are in the following areas: 3.9% in
California; 1.74% in the West (excluding California); 2.2% in Texas; and 2% in
the Midwest (excluding the Chicago metropolitan area). All remaining loans are
in the geographic market areas including the Chicago metropolitan area and the
Quad-Cities metropolitan area of Illinois and Iowa.

      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. A valuation allowance of $1,049 had been set up against the parent company
only Federal net operating loss carryforward in 1993, when the Corporation
adopted the provisions of SFAS No. 109. In reviewing its 1996 tax planning
strategies relating to the parent company only Federal net operating loss
carryforward, a portion which expires in 1999, the Corporation recognized that
it did not need that specific valuation allowance because of the effect of the
market value adjustment related to SFAS No. 115 on the parent company equity
portfolio. A correcting entry was made in 1996 to reverse the valuation
allowance and record the SFAS no. 115 adjustment. At the time of the correction,
the adjustment to equity (including the SFAS No. 115 adjustment) was less than
1% of equity. Management reviewed the effect of this adjustment on prior period
financial statements and determined it was immaterial to those financial
statements due to the amount of the adjustment and because any correcting entry
would have had no impact on the income or earnings per share of the Corporation.
No restatement of prior periods was made. The valuation allowance at December
31, 1996 relates solely to the 1995 and 1996 state net operating loss
carryforward. 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, 1996, the Federal net operating loss carryforward amounted to
approximately $3,641 which expires, if unused, in the years 1999 to 2001. At
December 31, 1996 and 1995, the State net operating loss carryforward amounted
to $42,510 and $23,549, respectively, which expires, if unused, in the years
2010 through 2012.
 
      At December 31, 1996, the Corporation had an alternative minimum tax
credit carryforward of approximately $207, which is not subject to expiration.

BORROWINGS, FHLB ADVANCES AND NOTES PAYABLE: (8)
 
      Included in short-term borrowings are Federal Home Loan advances with the
following maturities and rates:

</TABLE>
 
      The Corporation maintains qualifying collateral against these advances
including its Federal Home Loan Bank Stock and 1 - 4 Family residential
mortgages.
 
      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, 1996, the notes payable were a $15,000 note used to
finance the acquisition of AFC in 1994; a $15,000 note used for the acquisition
of FinSec and other equity securities and a $5,000 line for working capital of
which $2,800 was outstanding. Total outstandings were $32,800 at December 31,
1996. During 1995, the total lines were composed of a $23,000 demand loan used
for the acquisition of AFC and a $7,000 revolving line of credit. Total
outstandings were $20,600 at December 31, 1995.
 
      The notes payable bear interest at a floating rate tied to the prime rate
or LIBOR, are due on demand and are secured by stock of the Corporation's
subsidiary bank stock and with respect to the acquisition line, secured by
certain equity securities of the parent company.
 
RETIREMENT AND INCENTIVE PLANS: (9)
 
      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 $424 for
1996, $414 for 1995, and $337 for 1994.
 
      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.
 
      SF maintained certain retirement and incentive plans for its employees
including a qualified non-contributory defined benefit pension plan and a
Supplemental Retirement Agreement for one officer to provide supplemental
retirement, death and disability benefits. In conjunction with the acquisition,
these plans are in the process of being terminated and as of the most current
valuation are fully funded. No gain or loss on termination is expected.
 
CAPITAL STOCK: (10)
 
      On January 21, 1997, the Board of Directors of the Corporation approved a
3-for-2 stock split payable February 10, 1997 to stockholders of record on
February 3, 1997. The stock split has been recorded retroactively for
consolidated financial statement purposes by adjusting the par value of the
Corporation's common stock and the number of shares outstanding. Disclosures
regarding earnings per share and stock options have been adjusted accordingly
for all periods presented.
 
STOCK OPTION PLAN: (11)
 
      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 369,999
shares.
 
      The following table summarizes stock option transactions for 1996, 1995,
and 1994 giving effect to stock splits. At December 31, 1996, 65,250 option
shares under the 1990 Plan were

      In 1995, the Corporation derived tax deductions from the disposition of
stock option shares by participants 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.
 
      The range of options exercisable at December 31, 1996 are as follows:

      The Corporation accounts for its stock option plan under Accounting
Principle Board ("APB") Opinion No. 25, "Accounting for Stock Issued to
Employees". Accordingly, no compensation expense has been recognized for stock
options granted. SFAS 123 prescribes a fair value based method for determining
compensation expense under stock option plans, but allows corporations to use
APB No. 25 if they provide pro forma information compiled under the new
standard. Had compensation cost been computed using the methodology contained in
SFAS No. 123, net income would have been reduced by the following for options
issued in 1996 and 1995:

      The fair value of the options granted during 1996 and 1995 is estimated to
be $4.23 and $4.31, respectively, using the Black-Scholes option value model
with the following assumption for 1996 and 1995; dividend yield of 4.37% and
3.77%, a risk free interest rate of 5.95% and 7.37%, volatility of 24.38% and
22.11%, and an expected average life of five years.
 
      FinSec maintained five stock based plans, including an ESOP Plan, a
Supplemental Retirement Plan, a Recognition and Retention Plan ("RRP"), an
Incentive Stock Option Plan, and a Directors Stock Option Plan. At the
acquisition, any unearned or unexercised shares in the ESOP, RRP and Incentive
Stock Option and Directors Stock Option Plan were 100% vested. These plans are
in the process of being terminated and stock and/or cash is being paid to its
participants. Included in Other Assets in the Consolidated Balance Sheets is a
loan to the ESOP of $516 which, along with accrued interest, will be paid to the
Corporation when final termination is made.
 
RELATED-PARTY TRANSACTIONS: (12)
 
      Analysis of loans made to directors and executive officers of the
Corporation and subsidiaries is as follows:

      Directors of the Corporation and subsidiaries were customers of and had
transactions with the subsidiaries in the ordinary course of business during the
period presented above and additional 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 $229 in 1996, $250 in 1995, and $262 in 1994.
 
CONTINGENCIES: (13)
 
      During the first quarter of 1994, a judgment in the amount of $2,300 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 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.
 
      SF 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. There is a
contingent liability of $664 related to sales under this program.
 
DISCLOSURES ABOUT ESTIMATED FAIR
VALUE OF FINANCIAL INSTRUMENTS: (14)
 
      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:
 
CASH AND DUE FROM BANKS, FEDERAL
FUNDS SOLD AND INTEREST BEARING DEPOSITS - (A)
 
          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.
 
SECURITIES - (B)
 
          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 the security is carried at cost.
 
LOANS - (C)
 
          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.
 
DEPOSIT LIABILITIES - (D)
 
          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,
1996. 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.

SHORT TERM BORROWINGS AND NOTES
PAYABLE - (E)
 
          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.

INSTRUMENTS - (F)
 
          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.

LIMITATIONS - (G)
 
          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 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.
 
FINANCIAL INSTRUMENTS WITH OFF-
BALANCE SHEET RISK: (15)
 
      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, 1996 and 1995, the
subsidiary banks had the following financial instruments with off-balance-sheet
risk:

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.
 
REGULATORY REQUIREMENTS: (16)
 
      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, 1997, the subsidiary banks could have declared approximately $2,489
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, 1996 and 1995, the non-interest
bearing cash balances maintained to meet reserve requirements were $11,750 and
$10,527, respectively.
 
      The Corporation and its subsidiary banks are subject to regulatory capital
requirements administered by the Federal banking agencies. Under capital
adequacy guidelines and the regulatory framework for prompt corrective action,
banks must meet specific capital guidelines that involve quantitative measures
of assets, liabilities, and certain off-balance sheet items as calculated under
regulatory accounting practices.
 
      Quantitative measures established by regulation to ensure capital adequacy
require banks and bank holding companies to maintain minimum amounts and ratios
of total and Tier 1 capital to risk weighted assets and Tier 1 leverage capital
to average assets. If banks do not meet these minimum capital requirements, as
defined, bank regulators can initiate certain actions that could have a direct
material effect on a bank's financial statements. Management believes, as of
December 31, 1996, that the Corporation and its subsidiary banks meet all
capital adequacy requirements to which they are subject.
 
      As of December 31, 1996, the most recent notification from the Federal
Reserve Board categorized the Corporation and its subsidiary banks as well
capitalized under the regulatory framework for prompt corrective action. There
are no conditions or events since that notification that management believes
have changed the institution's categories. To be categorized as well
capitalized, banks must maintain minimum total risk-based, Tier 1 based and Tier
1 leverage ratios as set forth below.

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, 1996
and 1995, 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, 1996. 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 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 provide a reasonable basis for our opinion.
 
In our opinion, 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, 1996 and 1995 and the results of their
operations and cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

                             1996 COMPARED TO 1995
 
NET INCOME
 
Consolidated net income was $7,127,000, or $1.05 per share, on a fully diluted
basis in 1996, a decrease from the $12,493,000, or $1.89 per share, earned in
1995. All per share amounts have been adjusted for the 3-for-2 stock split
declared January 21, 1997. The return on average assets was 0.82% for 1996 and
1.55% for 1995. For each year, the return on average equity was 9% and 18.1%,
respectively. Return on average assets and equity for each year, calculated
including the effects of SFAS No. 115, would not be materially different.
 
Net income for 1996 included pre-tax securities gains on $159,000 compared to
pre-tax gains in 1995 of $4,731,000. The majority of the securities gains in
1996 and 1995 were part of the ongoing term portfolio management system which
Pinnacle has followed since 1988.
 
Net interest income decreased slightly (approximately 1%) primarily as a result
of the lower yields earned on taxable securities and a shift of deposits into
higher interest categories and the resulting higher interest costs.
 
Other income increased 5%, with the increase primarily due to the acquisition of
Financial Security ("FinSec") by Pinnacle. Other expense also increased 8%, with
approximately half the increase due to the acquisition and the remaining
increase due to a reversal of a loss contingency accrual in 1995 that related to
a case settled in the Corporation's favor. Absent these items, other expense
would have increased slightly or 1%.
 
Net income in 1996 included the effects of the acquisition of FinSec and its
subsidiary, Security Federal Savings & Loan Association of Chicago ("SF") which
occurred on September 30, 1996. FinSec was liquidated into Pinnacle while SF
remained a subsidiary of the Corporation. On January 31, 1997, SF will be merged
into PB. The acquisition was accounted for as a purchase and, accordingly, the
income and expense is included only from the date of acquisition.
 
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 banks and Federal
funds sold. Supporting liabilities primarily consist of deposits, short-term
borrowings and notes payable. A portion of Pinnacle's interest income is earned
on tax exempt investments 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
tax-equivalent basis.
 
Pinnacle's average earning assets were $801,822,000 in 1996, or 8% higher than
the previous year. The increase in average earning assets was due to the
acquisition as well as the increase in average loans from 1995. Offsetting the
increase in average earning assets was the decrease in the net interest margin.
The net interest margin decreased 39 basis points to 3.51% in 1996 compared to
3.90% in 1995. The decrease in the net interest margin is a result of lower
yields earned primarily on taxable securities, offset by the increase in the
cost of deposits. Net interest income on a fully-equivalent basis was
$28,147,000, or 3% lower than a year ago.
 
The yield earned on total earning assets was 7.14% in 1996 compared to 7.36% in
1995. The decrease resulted primarily from the lower level of yields earned on
taxable securities as well as interest-bearing deposits. The yield earned on
interest-bearing deposits decreased 83 basis points as a result of the decrease
in rates on overnight deposits as well as the decrease in average balances in
this category and the maturity of higher-yielding interest-bearing deposits
acquired in 1995 from the AFC acquisition. The average rate on taxable
securities decreased 38 basis points to 5.78% from 6.16% of a year ago. Average
balances in taxable securities increased $20,680,000; however, the decrease in
the yield earned offset the increase in the average balances, and interest
income on taxable securities decreased $214,000. The average yield earned on
loans decreased 20 basis points to 8.34% from 8.54% of a year ago. The average
balance in loans increased 21%, partly from the acquisition. The majority of the
growth in average loans resulted from a concerted effort on the part of
management to increase the loan portfolio without sacrificing the credit quality
of the portfolio. The effect on the average balance of loans due to the
acquisition will be more visible in 1997; as evidenced by the increase in the
ratio of loans to earning assets at December 31, 1996 of 54%, compared to the
ratio in 1995 of 41%. The ratio of average loans to average earning assets

was 47% in 1996 compared to 42% a year ago. These factors resulted in the
increase in interest income on average loans of $4,781,000, more than offsetting
the slight decrease in the yield. Total interest income, on a fully taxable
equivalent basis, increased $2,506,000 due to the positive impact of the
increased loan portfolio.
 
The average cost of interest-bearing liabilities increased 19 basis points to
4.21% in 1996 from 4.02% in 1995. The average rate paid on interest-bearing
demand deposits increased slightly by 7 basis points to 2.07% while the rate
paid on savings deposits decreased 15 basis points. These deposit categories are
considered core deposit categories and are less susceptible to market and rate
changes. The interest rate paid on money market deposits increased 50 basis
points to 3.44% in 1996. Pinnacle has taken action at appropriate intervals to
adjust the rates paid on all deposits 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, thus the increase in that rate
category. The average rate paid on other time deposits has increased 25 basis
points to 5.53%. Rates have remained relatively flat on time deposits for 1996;
however, the effect of management's increase in rates paid on longer-term time
deposits in previous years are continuing to add to the increases in rates paid.
The acquisition of SF has added to the increase in rates as certain of time
deposits acquired were at higher rates than those offered by Pinnacle at the
time of acquisition. Absent the affects of the acquisition of SF, the average
balance in certain deposit accounts have decreased, particularly in savings and
money market deposits, as the increase on rates paid on time deposits has caused
customers to switch those deposits into other time deposits, as evidenced by the
increase in the other time deposit categories. Interest expense paid on all
deposits increased $2,908,000.
 
The average balance in short-term borrowings increased for two reasons. The
increase in loan demand contributed to the $11,503,000 increase in average
balances, as well as the acquisition of SF, whose short-term borrowings include
fixed-term advances from the Federal Home Loan Bank. The average rate paid on
short-term borrowings decreased 60 basis points; however, the increase in
average balances resulted in increased interest expense of $689,000. The
interest rate paid on notes payable decreased 84 basis points. The decrease was
due to lower rates in indices (Prime or LIBOR) which are the interest rate basis
to which the notes payable are tied. Average notes payable balances slightly
decreased.
 
Interest expense for 1996 has increased $3,378,000 compared to 1995. An increase
in the average interest-bearing liabilities of $51,290,000 and the shift of
higher paying deposits categories has resulted in the increase.

31, 1996, 1995 and 1994 is included in Table 1. An Analysis of the Volume/Rate
Variance for the last three years is found in Table 2.

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 potential losses in the loan portfolio, and prevailing economic
conditions.
 
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 a bi-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 and banking regulatory authorities.
 
There has been no provision for loan losses in both 1996 and 1995. Pinnacle had
net charge-offs of $641,000 or 0.17% of average loans compared to $151,000 or
0.05% of average loans in 1995. The ratio of the allowance for loan losses to
total loans was 1.59% at December 31, 1996 compared to 1.95% of a year ago.
While Pinnacle's ratio of

allowance for loan losses to total loans has decreased from a year ago, and the
ratio of net charge-offs to average loans has increased, management made no
provision for loan losses for the past two years and believes the allowance for
loan losses is adequate due to the following factors. First, a significant
portion of its loan portfolio is in residential real estate, particularly the
loans acquired in the FinSec acquisition, and the majority of the loans in this
category are within the loan policy guidelines of loan to value ratio of 80%.
Second, the total ratio of non-performing loans to total loans declined during
1996 to 1.79% at December 31, 1996 from 2.59% at year-end 1995. Third, the loan
review process by management is operating effectively. This loan review process
was instituted at SF and significant watch list credits were monitored by
Pinnacle management prior to the acquisition on September 30, 1996, as part of
its due diligence.
 
At December 31, 1996, total non-performing loans, defined as non-accrual loans;
loans past due greater than 90 days and still accruing; and restructured loans,
were $9,404,000 compared with $8,015,000 of a year ago. While this is a
significant increase, 51% of the non-performing loans at December 31, 1996
resulted from the acquisition of SF. Prior to the acquisition, SF provided
$1,275,000 to their allowance for loan losses to cover potential loan losses on
classified loans. All restructured loans, including a $494,000 loan acquired
from SF, are performing as agreed. Loans considered impaired under SFAS No. 114
and disclosed in the Notes to the Financial Statements are included in the
non-performing category. These included non-accrual loans, restructured loans,
and loans classified as at least doubtful under Pinnacle's credit risk
classification system. Without the acquisition, non-performing loans would have
decreased $3,453,000 from a year ago.
 
In addition, Pinnacle held $939,000 classified as other real estate owned
("OREO") at December 31, 1996. 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 property is recorded as an offset
to expense. During 1996, all property carried at December 31, 1995 was sold with
no significant impact on the results of operations. The remaining OREO consists
of $667,000 acquired from SF and $272,000 at PB.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS
--------------------------------------------------------------------------------
 
Total non-performing assets were $10,343,000, or 1.97% of total loans plus other
real estate owned at December 31, 1996. Total non-performing assets were 0.99%
of total assets at year end. Table 4 provides data regarding non-performing
assets.
 
NET SECURITIES GAINS
 
In 1996, net securities gains were not a significant factor in the earnings. On
a pre-tax basis, net securities gains were $159,000 compared to $4,731,000 in
1995. The net gains realized in 1996 consisted of gross gains of $349,000 and
gross losses of $190,000.
 
The net gains in 1996 are primarily related to the sales in Pinnacle's U. S.
Government securities portfolio. The decrease in the gains taken is primarily a
product of the slope of the yield curve, which remained relatively flat in 1996.
The gains in 1995 also related to Pinnacle's U. S. Government securities
portfolio as well as the sale of an equity security and sale of securities
acquired through the purchase of AFC in 1995. At December 31, 1996, the U. S.
Government securities had a remaining maturity of fifteen 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 has
been crucial to Pinnacle because of its relatively low loan to asset ratio,
while increased to 50% at year-end 1996 due to the acquisition, on average was
43% throughout 1996. Management has always viewed the gains recorded on the U.
S. Government security term portfolio 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 30 basis points and, by
including the net gains since the inception of the program, the total yield is
130 basis points higher than the same Index. For 1996, due to the relative
flatness of the yield curve, the portfolio has only outperformed the Index by 16
basis points, and including the net gain by 20 basis points.
 
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 $5,279,000 for 1996 compared to
$4,918,000 in 1995. The increase was due primarily to the acquisition. Trust
services decreased slightly due primarily to the decrease in estate
administration fees. Assets under management at year end amounted to
$268,000,000, or 11% above the total one year earlier. The increase in the
amount of assets under management was due primarily as a result of the increase
in market value of assets under management. Fee income related to that increased
value will be realized in 1997.
 
NON-INTEREST EXPENSE
 
Non-interest expense totalled $25,700,000 an increase of 8% of a year ago.
Employee compensation and benefits increased 5% primarily due to general
employee raises. The acquisition of SF added approximately $376,000 to the
increase in employee compensation in 1996. Occupancy expense totalled
$2,674,000, or 15% lower than a year ago. Included in 1995 was a $434,000 write-
off relating to the demolition of an old branch

office building in 1995 and a $150,000 accrual for a lease buyout on a storage
facility which occurred in January, 1996. Absent these two factors, occupancy
expense would have increased 5%, primarily due to the acquisition. Other expense
increased 22% primarily due to the acquisition which contributed 23% of the
increase, the result of a reversal of a loss contingency accrual in 1995 for
litigation settled in Pinnacle's favor, and a $744,000 charge to earnings for
the SAIF fund recapitalization recorded in the third quarter of 1996. Absent
these changes, other expense would have decreased 4%.
 
INCOME TAXES
 
Pinnacle's Federal and State income tax return is prepared on a consolidated
basis including the accounts of its subsidiaries. Due to the lower level of
pre-tax income, there was a reduction in the Federal tax provision to $2,050,000
compared to $3,139,000 of a year ago. There continues to be no provision for
state income taxes in 1996 as in 1995 due to the significant holdings of U. S.
Government securities which are exempt from state tax. See Note 7 to the
Consolidated Financial Statements for additional detail on the provision for
taxes.
 
                                   NET INCOME
 
                             1995 COMPARED TO 1994
 
NET INCOME
 
Consolidated net income was $12,493,000, or $1.89 per share, on a fully diluted
basis in 1995, an increase from the $2,255,000, or $0.34 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

Management's Discussion and Analysis of Financial Condition
and Results of Operations
--------------------------------------------------------------------------------
 
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.
 
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
 
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. All of Pinnacle's impaired loans are included in the nonperforming
category.
 
In addition, Pinnacle held $284,000 classified as other real estate owned at
December 31, 1995. Total non-performing assets were $8,299,000, or 2.68% of
total loans plus other real estate owned at December 31, 1995. Total
non-performing 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 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
 
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.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS
--------------------------------------------------------------------------------
 
INCOME TAXES
 
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. A detailed analysis of income taxes and the
components of the deferred tax assets is contained in Note 7 to the Consolidated
Financial Statements. At December 31, 1995, Pinnacle had a consolidated Federal
net 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.
 
                                 BALANCE SHEET
 
Total assets were $1,048,376,000 at December 31, 1996, or 28% higher than total
assets of $818,697,000 at year-end 1995. The increase in total assets related
primarily to the acquisition of FinSec on September 30, 1996.
 
SECURITIES
 
Until the acquisition, Pinnacle's securities portfolio was its most significant
Balance Sheet asset and still totals 41% of total assets. All securities are
available for sale and carried at fair value with corresponding (after tax)
valuation adjustments included in stockholders' equity. Total securities were
$434,558,000 on December 31, 1996 and consisted of U. S. Government securities
of $373,072,000; mortgage-backed securities and collateralized mortgage
obligations totalled $5,943,000; State and municipal bonds totalled $23,450,000
and corporate and other securities totalled $32,093,000. Total securities
increased 2% in 1996. The increase was primarily due to the increased in
purchases of parent company only equity securities as well as the increased
market value of those same equity securities. A detailed analysis of securities,
including unrealized gains and losses as well as maturity schedules is contained
in Note 3 to the Consolidated Financial Statements.
 
Currently, Pinnacle is not using any derivative products for hedging or other
purposes.
 
LOANS
 
Total loans were $525,069,000 at December 31, 1996, an increase of 70% from a
year ago. All categories of loans increased due to the acquisition of FinSec,
with the largest increase from the acquisition in real estate loans. Absent the
effects of the acquisition, loans increased $43,413,000, or 14%, with the
largest increase in commercial and residential real estate related loans.
Pinnacle's loan to asset ratio increased to 50% from 38% of a year ago due to
the acquisition. This ratio, while much higher than previous years, still
remains lower than the industry average of approximately 60%. Management's goal
is to continue to increase this ratio through quality loan growth across a
consistent spectrum of commercial, consumer and real estate borrowers. Strategic
plans include maintaining the level of loans at SF at its current balance of
approximately $170,000,000 by allowing paydowns on participated loans as
scheduled, potential package loan sales and offsetting this by growth in SF's
natural geographic area.
 
At December 31, 1996, Pinnacle's mix of loans consisted of 69% in real estate
loans, 21% in commercial loans and the remainder in consumer loans. The shift in
mix of loans to real estate loans relate primarily to the make-up of the SF
portfolio which, as a thrift, emphasizes lending in this area. See Note 4 in the
Notes to Consolidated Financial Statements for a detailed analysis of loans by
composition and geographic mix.

--------------------------------------------------------------------------------
 
DEPOSITS
 
Total deposits were $877,552,000 at December 31, 1996, or 23% higher than
year-end 1995. All of the increase related to the acquisition. Table 5 provides
an analysis of deposits by category for the past three years.
 
Absent the effect of the acquisition, interest-bearing demand deposits have
decreased $5,000,000 and savings deposits have dropped approximately
$13,000,000. Other time deposits have increased approximately $8,000,000.
Management believes the drop in savings and the corresponding increase in time
deposits was due to Pinnacle customers being more willing to commit their funds
to defined periods of time. Management continues to take an active role to
monitor interest rates on deposits and provide products to reduce the
disintermediation of funds.
 
Pinnacle's deposit base continues to be made up of a high amount of low cost
core deposits in comparison with peer group institutions. The impact on earnings
of this deposit base has been somewhat offset by increased rates on these
deposits in the earlier part of the year and the increase in rates paid on time
deposits caused a shift from savings to time deposits.
 
GOODWILL
 
Goodwill and other intangibles amounted to $25,366,000, or 25% of stockholders'
equity, at December 31, 1996. Goodwill and other intangibles relate to premiums
paid in Pinnacle's acquisitions. The increase from year-end 1995 was the result
of the acquisition of FinSec, where approximately $8,100,000 in goodwill was
recorded.
 
DEFERRED INCOME TAXES
 
The primary components of Pinnacle's net deferred tax asset at December 31, 1996
are differences between the book and tax bases of securities and other assets,
allowance for loan losses, purchased accounting adjustments, deferred
compensation and deferred loan fees. A detailed analysis of the components of
the deferred tax assets is contained in Note 7 to the Consolidated financial
Statements. At December 31, 1996, Pinnacle had a consolidated Federal net
operating loss carryforward of $3,641,000 the benefit of which is included in
the deferred tax asset and, if not used, expires from the years 1999 to 2001.
All of the Federal net operating loss carryforward relates to the parent company
and is subject to significant limitations on its usage. It is Pinnacle's intent
to utilize certain of the net operating loss carryforward in 1997 through
potential sales of certain of its equity portfolio in order not to lose the cash
benefit of the carryforward. At December 31, 1996, Pinnacle had, for state tax
purposes, a net operating loss carryforward of $42,510,000 which expires, if
unused, in the years 2010 through 2012.
 
SHORT-TERM BORROWINGS
 
Federal funds purchased, securities sold under agreements to repurchase
("repos") and FHLB advances constitute all of Pinnacle's short-term borrowings.
These short-term borrowings are not subject to FDIC deposit insurance premiums
or reserve requirements.
 
Short-term borrowings and FHLB advances increased to $28,525,000 at December 31,
1996 from no balance of a year ago. The increase was due to added loan demand
and the acquisition,

NOTES PAYABLE
 
Pinnacle had $32,800,000 outstanding in notes payable at December 31, 1996,
compared to $20,600,000 at December 31, 1995. During 1996, Pinnacle increased
borrowings by $12,200,000 and increased the total outstanding line to
$35,000,000. The borrowings included a refinancing of the line of $15,000,000 to
acquire AFC in 1995; $15,000,000 to finance a portion of the FinSec acquisition
and other equity security purchases; and the remaining $2,800,000 used for other
corporate needs. Pinnacle had a revolving line of credit of $5,000,000 at
December 31, 1996, of which $2,800,000 was drawn.

Total stockholders' equity of Pinnacle was $100,824,000 at December 31, 1996 up
28% from $78,961,000 at December 31, 1995. The ratio of equity to assets was
9.62% and 9.64% 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. 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, 1996,
and December 31, 1995, Pinnacle's total risk-based capital ratio was 15.01% and
18.09%, respectively, assuming the deduction of all goodwill and other
intangibles in compliance with the guidelines. The reduction in the ratio was
the result of the FinSec acquisition. Each of Pinnacle's subsidiary banks must
meet similar minimum capital requirements as prescribed by Federal and state
banking regulatory authorities. At December 31, 1996, Pinnacle and each of its
subsidiary banks was in compliance with the current capital guidelines. For a
detailed analysis of regulatory capital ratios, see Note 16 to the Consolidated
Financial Statements. This footnote includes capital ratios for Pinnacle and
certain of its significant subsidiaries.
 
Book value per share was $13.23 at December 31, 1996 compared to $12.03 at
December 31, 1995. During 1996, Pinnacle repurchased 236,879 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 $0.83 per
share were paid in 1996. Shares totalling 1,285,413 (adjusted for stock split)
were issued for the acquisition of FinSec.
 
                    LIQUIDITY AND INTEREST RATE SENSITIVITY
 
As is characteristic of the banking industry, Pinnacle's indicators of liquidity
are principally its deposit base, loan and securities 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, 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
1996, cash flows were generated from a $20,860,000 net decrease in securities, a
$31,990,000 decrease in interest-bearing deposits, a $12,200,000 net increase in
notes payable, $7,492,000 from earnings, and a $2,825,000 increase in short-term
borrowings. Cash flow uses and needs included a $21,817,000 decrease in
deposits, a $39,836,000 increase in loans, net cash of $19,050,000 to purchase
FinSec, and $10,436,000 to pay dividends and repurchase common stock. Pinnacle's
net cash position decreased $18,278,000 with the majority of the decrease 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 are funded with both debt and issuance of stock. Reductions of debt
would be made from Pinnacle's earnings. At December 31, 1996, Pinnacle had a
line of credit of $5,000,000 with an unaffiliated bank.
 
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, 1997, bank
subsidiaries could have declared approximately $2,489,000 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.
 
Management had no significant commitments for capital expenditures at December
31, 1996. It is the intent of management to merge both SF and Pinnacle Bank, FSB
into PB in the first half of 1997. No significant change is anticipated in the
financial condition of Pinnacle due to the merger.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

is one method of monitoring the interest rate risk of the Corporation. 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. The Corporation
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 7 includes U. S. Government securities as
repricing within the earliest period presented since these securities are
recorded as available for sale and have been historically sold prior to maturity
as part of Pinnacle's portfolio funds management system. Table 7 also 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 2.93x for 1-90 days;
2.04x for 91-180 days; and 1.69x for 181-365 days.
