PART I - FINANCIAL INFORMATION

ITEM 1. FINANCIAL STATEMENTS

APPLICATION OF CRITICAL ACCOUNTING POLICIES

      ALLOWANCE FOR LOAN LOSSES - The allowance for loan losses is calculated
with the objective of maintaining a reserve sufficient to absorb estimated
probable loan losses. Loan losses are charged against the allowance when
management believes loan balances are uncollectible. Subsequent recoveries, if
any, are credited to the allowance. Management's determination of the adequacy
of the allowance is based on periodic evaluations of the loan portfolio and
other relevant factors. This evaluation is inherently subjective as it requires
an estimate of the loss for each risk rating and for each impaired loan, an
estimate of the amounts and timing of expected future cash flows and an estimate
of the value of collateral.

      A loan is considered impaired when, based on current information and
events, it is probable that the Bank will be unable to collect the scheduled
payments of principal and interest when due, according to the contractual terms
of the loan agreement. Factors considered by management in determining
impairment include payment status, collateral value and the probability of
collecting principal and interest payments when due. Impairment is measured on a
loan-by-loan basis for commercial and construction loans by either the present
value of expected future cash flows discounted at the loan's effective interest
rate, the loan's obtainable market price, or the fair value of the collateral if
the loan is collateral dependent. Large groups of homogeneous loans are
collectively evaluated for impairment. Accordingly, the Bank does not separately
identify individual consumer and residential loans for impairment disclosures.

      ACCOUNTING FOR GOODWILL - Effective January 1, 2002, the Company adopted
Statement of Financial Standard No. 142, "Goodwill and Other Intangible Assets"
(SFAS 142), which changes the Corporation's accounting for goodwill and other
intangible assets. Generally, intangible assets that meet certain criteria are
recognized and subsequently amortized over their estimated useful lives.
Goodwill and intangible assets with indefinite lives are not amortized. However,
such assets are tested for impairment at adoption of SFAS 142 and at least
annually thereafter. No impairment loss was recorded upon the adoption of SFAS
142 in 2002, nor has any impairment loss been recorded since the adoption of
this standard.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 - BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Rule 10-01 of
Regulation S-X. We have condensed or omitted certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles. You should read these condensed
financial statements in conjunction with our audited financial statements for
the year ended December 31, 2005 and notes thereto included in PSB Group, Inc.'s
Form 10-K filed with the Securities and Exchange Commission on March 30, 2006.
In the opinion of management, all adjustments necessary to present fairly the
financial position, results of operations, and cash flows of PSB Group, Inc. as
of June 30, 2006 and for the periods then ended have been made. Those
adjustments consist only of normal and recurring adjustments. The results of
operations for the six-month period ended June 30, 2006 are not necessarily
indicative of the results to be expected for the full year.

PSB Group, Inc. was formed as a holding company for Peoples State Bank on
February 28, 2003 pursuant to a plan of reorganization adopted by Peoples State
Bank and its shareholders. Pursuant to the reorganization, each share of the
Bank's stock was exchanged for three shares of stock in the holding company. The
reorganization had no material financial impact and is reflected for all prior
periods presented. Per share amounts have been retroactively restated to reflect
the three-for-one exchange of stock.

The Company places loans in non-accrual status when, in the opinion of
management, uncertainty exists as to the ultimate collection of principal and
interest. Management knows of no loans (other than those that are immaterial in
amount) which have not been disclosed below which cause it to have doubts as to
the ability of the borrowers to comply with the contractual loan terms, or which
may have a material effect on the Company's balance sheet or results from
operations. Non-performing assets consists of non-accrual loans, loans past due
90 or more days, restructured loans and real estate that has been acquired in
full or partial satisfaction of loan obligations or upon foreclosure. As of June
30, 2006, other real estate owned consisted of two properties. Management does
not anticipate any material loss as the result of the disposal of these
properties. Non-performing loans have increased $1.2 million, or 29% since
December 31, 2005. The following table summarizes non-performing assets (dollars
in thousands):

periodic analysis of the portfolio, economic conditions and trends, historical
credit loss experience, borrowers' ability to repay and collateral values.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

OVERVIEW

PSB Group, Inc. (the "Company") was formed on February 28, 2003 as a bank
holding company for the purpose of owning Peoples State Bank (the "Bank")
pursuant to a plan of reorganization adopted by the Bank and its shareholders.
Pursuant to the reorganization, each share of Peoples State Bank stock held by
existing shareholders of the Bank was exchanged for three shares of common stock
of PSB Group, Inc. The reorganization had no consolidated financial statement
impact. Share amounts for all prior periods presented have been restated to
reflect the reorganization.

The Bank was incorporated and chartered under the laws of the state of Michigan
in 1909. We operated as a unit bank until July 20, 1992, when we opened our
first branch office in Sterling Heights, Michigan. In May 1998, the Bank
acquired Madison National Bank, Madison Heights, Michigan ("Madison"). On May 1,
2000, the Bank acquired 100% of the common stock of Universal Mortgage
Corporation, a southeast Michigan based mortgage lender. Today we operate 11
banking offices, 6 mortgage offices and two shared loan production offices, with
an additional banking office under construction in Troy, Michigan.

We provide customary retail and commercial banking services to our customers,
including checking and savings accounts, time deposits, safe deposit facilities,
commercial loans, real estate mortgage loans, installment loans, IRAs and night
depository facilities. Our deposits are insured by the FDIC to applicable legal
limits and we are supervised and regulated by the FDIC and Michigan Office of
Financial and Insurance Services.

We provide a full range of retail and commercial banking services designed to
meet the borrowing and depository needs of small and medium-sized businesses and
consumers in local areas. Substantially all of our loans are to customers
located within our service area. We have no foreign loans or highly leveraged
transaction loans, as defined by the Federal Reserve Board ("FRB"). We conduct
our lending activities pursuant to the loan policies adopted by our Board of
Directors. These loan policies grant individual loan officers authority to make
secured and unsecured loans in specific dollar amounts; senior officers or
various loan committees must approve larger loans. Our management information
systems and loan review policies are designed to monitor lending sufficiently to
ensure adherence to our loan policies.

We also offer a full range of deposit and personal banking services insured by
the Federal Deposit Insurance Corporation ("FDIC"), including (i) commercial
checking and small business checking products, (ii) retirement accounts such as
Individual Retirement Accounts ("IRA"), (iii) retail deposit services such as
certificates of deposits, money market accounts, savings accounts, checking
account products and Automated Teller Machines ("ATMs"), Point of Sale and other
electronic services, and (iv) other personal miscellaneous services such as safe
deposit boxes, foreign draft, foreign currency exchanges, night depository
services, travelers checks, merchant credit cards, direct deposit of payroll,
U.S. savings bonds, official bank checks and money orders. We also offer credit
cards and internet banking. We provide commercial and public fund accounts with
money market sweep accounts through Federated Investments, a third party vendor.
We also provide investment services through Vision Investment Services, Inc.
Full-time representatives work at various branch offices

                                       13
<PAGE>

and offer a full range of investment products. Substantially all of our deposits
are from local market areas surrounding each of our offices.

The consolidated financial statements include the accounts of PSB Group, Inc.
and its wholly owned subsidiaries, Peoples State Bank and PSB Capital, Inc. PSB
Insurance Agency, Inc. and Universal Mortgage Company are wholly owned
subsidiaries of Peoples State Bank. PSB Capital, Inc. was formed in October,
2004. Through June 30, 2006, there has been no business transacted by PSB
Capital, Inc. All significant inter-company transactions are eliminated in
consolidation.

Net income is derived primarily from net interest income, which is the
difference between interest earned on the Bank's loan and investment portfolios
and its cost of funds, primarily interest paid on deposits and borrowings. The
volume of, and yields earned, on loans and investments and the volume of, and
rates paid, on deposits determine net interest income.

The Company adopted SFAS 123(R), Accounting for Share Based Payments in 2006. To
date, the effects of this change have been insignificant.

FINANCIAL CONDITION

Company assets consist of loans, investment securities, bank premises and
equipment, cash and other operating assets. Total assets increased approximately
$6 million, or 1.2% to $501 million at June 30, 2006 from $495 million at
December 31, 2005. The balance of our investment securities decreased by
approximately $4.4 million to $89.2 million at June 30, 2006 as compared to
$93.6 million at December 31, 2005. Our loan portfolio increased approximately
$15.7 million to $380.8 million at June 30, 2006. This was the result of a $10.3
million increase in loans secured by real estate and a $6.1 million increase in
other commercial loans, offset partially by a $649 thousand decrease in consumer
loans. Loans held for sale decreased by $4.6 million to $1.6 million at June 30,
2006. All other assets decreased approximately $900 thousand at June 30, 2006.
This was primarily due to the sale of a previously closed branch facility.

The allowance for loan losses increased $137 thousand during the first six
months of 2006. As a percentage of total loans, the allowance remained at 1.00%.
Management believes this reserve is sufficient to meet anticipated future loan
losses. The discussions set forth in "Note 3 - Loans" and "Note 4 - Allowance
for Possible Loan Losses" to the financial statements contained in this report
are hereby incorporated by this reference.

Total liabilities increased $5.8 million to $457.6 million at June 30, 2006 from
$451.8 million at December 31, 2005. This was mainly due to a $22.3 million, or
5.3% increase in total deposits to $447 million at June 30, 2006 from $425
million at December 31, 2005. We realized a $32.1 million increase in
certificates of deposit and a $3.6 million increase in non-interest bearing
demand balances. The increase in certificates of deposit includes $9.2 million
in brokered deposits that we acquired. Proceeds from the brokered deposits were
used, among other things, to pay off our $5 million long-term FHLB advance. The
increases were partially offset by a $7.2 million drop in interest bearing
demand balances and a $6.2 million drop in savings balances. The increase in
deposits was offset by a $16.6 million decrease in our borrowings, in funding
our $6 million increase in total assets.

FINANCIAL RESULTS

Three Months Ended June 30, 2006

Net income for the three months ended June 30, 2006 was $938 thousand compared
to $1.3 million for the same period in 2005. Total interest income increased
$1.2 million in the second quarter 2006 compared to the second quarter 2005.
Interest and fees on loans increased $1.2 million in the second quarter 2006
over the second quarter 2005. Interest on securities and federal funds sold
remained relatively flat, increasing $5 thousand for the same period. The
increase in interest and fees on loans in the second quarter 2006 compared to
the second quarter 2005 was due both to higher interest rates in 2006 and also
higher average balances. Average loan balances increased $31.8 million between
the two periods and we earned approximately 75 basis points more in 2006 than
2005.

Interest expense increased $1.1 million in the second quarter 2006 as compared
to the same period in 2005. The increased interest expense is due mainly to
higher balances and higher rates paid on our Prime Savings Plus product and
Certificates of Deposit. Average Prime Savings Plus balances are about $1.4
million higher in the second quarter 2006 than they were in the second quarter
2005, and, we paid about 91 basis points higher on this product in the second
quarter 2006 than the second quarter 2005. Average certificate of deposit
balances are approximately $45.1 million higher in the second quarter 2006 than
the second quarter 2005, and we paid 84 basis points higher in the second
quarter 2006 than 2005.

During the second quarter 2006 we recorded a $291 thousand provision for loan
losses compared to the $145 thousand provision in the second quarter 2005. This
increase was mainly due to a large provision taken in anticipation of a loss
related to one large commercial loan.

Total other income was about $261 thousand lower in the second quarter 2006 than
the second quarter 2005. Reduced commercial loan fees, mainly broker fees,
accounted for $247 thousand of this decrease. Lower gains on the sale of
mortgages and mortgage servicing rights also contributed to the drop in Other
Income.

Total other operating expenses increased $334 thousand in the second quarter
2006 over the same period in 2005. Salaries and benefits accounted for $144
thousand of this increase. Higher bonus and profit sharing accruals accounted
for $90 thousand of this, the result of a reduction in this expense that was
recorded in the second quarter 2005. Occupancy expenses were $193 thousand
higher in the second quarter 2006 than the second quarter 2005. This increase is
due in a large part to the opening of a new branch in August 2005, the
acquisition of two new mortgage production offices in June 2005 and to rent
being paid on our Troy, Michigan branch that is currently under construction.
Legal and professional fees are down $32 thousand in the second quarter 2006
from the second quarter 2005. Other operating expenses increased $29 thousand in
the second quarter 2006 over the second quarter 2005.

Six Months Ended June 30, 2006

Net income for the six months ended June 30, 2006 was $1.7 million compared to
$2.2 million for the same period in 2005. Total interest income increased $2.6
million in the first six months of 2006 compared to the first six months of
2005. Interest and fees on loans increased $2.4 million. 2006 year to date
average loan balances increased $21.2 million over the 2005 averages. This
increase, and the 94 basis point increase in yield accounted for the increase in
interest and fees on loans.

                                       15
<PAGE>

Interest income on investment securities increased $120 thousand in the first
half of 2006 over the first half of 2005. Our average investment in securities
and federal funds sold is actually about $8.8 million lower so far in 2006 than
it was in the first half of 2005, but we increased our yield by shifting
maturing U. S. Agency investments into higher yielding municipal securities.

Total interest expense increased $2.2 million in the first six months of 2006
compared to the same period in 2005. Approximately $1.4 million of this increase
is due to our certificates of deposit. Our average balance in certificates of
deposit in the first half of 2006 is $37.3 million higher than it was in the
first half of 2005. In addition, we paid on average, 95 basis points higher on
these deposits so far in 2006 than we did in the first half of 2005. Another
$701 thousand of the increase is due to our Prime Savings Plus product. During
the first six months of 2006, we held an average of $93.7 million in Prime
Savings Plus balances compared to $86.1 million in the first six months of 2005.
Also, we paid 124 basis points more on these balances in 2006 than 2005.

During the first six months of 2006, we recorded a $479 thousand provision for
loan losses compared to a $549 thousand provision in the first six months of
2005.

Total other income was about $388 thousand lower in the first half of 2006 than
the first half of 2005. Deposit service charges remained relatively consistent
between the two periods, dropping $26 thousand in 2006. Other non-interest
income decreased $362 thousand, comparing the first half of 2006 to the first
half of 2005. This included a $267 thousand decrease in commercial loan fees,
$180,000 of which was a drop in broker fees, and an $88 thousand drop in the
gains on the sale of mortgages, which is mainly due to an overall drop in
mortgage loan volume. We also realized a $77 thousand drop in the gains on the
sale of securities in 2006. The decreases were partially offset by a $43
thousand increase in investment referral income.

Total operating expenses increased $913 thousand in the first six months of 2006
compared to the first six months of 2005. Total salary and benefits expense
increased $363 thousand. This includes a $126 thousand increase in accrued
bonuses and a $229 thousand increase in salaries and other benefits due mainly
to the increased staffing to accommodate the new branch and the mortgage
production offices that were acquired last year. Occupancy costs increased $393
thousand over the 2005 level. Again, this is mainly due to the new branch and
mortgage production offices acquired last year. Year-to-date legal and
professional fees remained relatively stable, increasing $3 thousand over 2005.
Other operating expenses increased $154 thousand in the first half of 2006 over
the first half of 2005. Telephone expense is up $45 thousand and stationery and
supplies expense is up $19 thousand, both a direct result of the additional
offices. Advertising expense is $188 thousand over the 2005 level due to the
fact that many of our 2006 advertising programs were scheduled for the first
half of the year. Partially offsetting these increases is the fact that a $54
thousand processing loss that we suffered in 2005 was not repeated in 2006.

LIQUIDITY

The Company manages its liquidity position with the objective of maintaining
sufficient funds to respond to the needs of depositors and borrowers and to take
advantage of earnings enhancement opportunities. In addition to the normal
inflow of funds from core-deposit growth, together with repayments and
maturities of loans and investments, the Company utilizes other short-term
funding

                                       16

sources such as Federal Home Loan Bank advances and overnight federal funds
purchases from correspondent banks.

During the six months ended June 30, 2006, $4 million in cash was provided by
operations. This, plus $22.3 million in cash provided through increased deposits
and $8 million from the pay-down of loans held for sale and investment
securities was used to increase our loan portfolio by $16 million and pay-down
our short-term and long-term borrowings by $17.2 million. In addition, we paid
$1 million in cash dividends during the period. During the six months ended June
30, 2006, we experienced a net increase of approximately $56 thousand in cash
and cash equivalents.

OFF BALANCE SHEET ARRANGEMENTS AND CONTRACTUAL OBLIGATIONS

The only significant off balance sheet obligations incurred routinely by the
Company are its commitments to extend credit and its stand-by letters of credit.
At June 30, 2006, the Company had commitments to extend credit of $69.4 million
and stand-by letters of credit of $3.8 million compared with $66.6 million and
$3.1 million, respectively, at December 31, 2005.

CAPITAL RESOURCES

Banks are expected to meet a minimum risk-based capital to risk-weighted assets
ratio of 8%, of which at least one-half (4%) must be in the form of Tier 1
(core) capital. The remaining one-half may be in the form of Tier 1 or Tier 2
(supplemental) capital. The amount of loan loss allowance that may be included
in capital is limited to 1.25% of risk-weighted assets. The Bank is currently,
and expects to continue to be, in compliance with these guidelines. The
following table shows the capital totals and ratios for the Bank as of June 30,
2006:

<TABLE>
<S>                                                  <C>
Tier 1 capital                                       $ 40,010
Total capital                                        $ 43,817
Tier 1 capital to risk-weighted assets                  10.48%
Total capital to risk-weighted assets                   11.48%

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      To a great extent, the Company's operating strategies focus on
asset/liability management. The purpose of its Asset Liability Management Policy
is to provide stable net interest income growth while both maintaining adequate
liquidity and protecting the Bank's earnings from undue interest rate risk. The
Bank follows its Asset/Liability Management Policy for controlling exposure to
interest rate risk. The Policy is established by management and approved by the
Board of Directors.

The Company's balance sheet consists of investments in interest earning assets
(investment securities and loans) that are funded by interest bearing
liabilities (deposits and borrowings). These instruments have varying levels of
sensitivity to changes in market interest rates which results in interest rate
risk. Our policies place strong emphasis on stabilizing net interest margin,
with the goal of providing a consistent level of satisfactory earnings.

                                       17
<PAGE>

An interest sensitivity model is the primary tool used in assessing interest
rate risk, by estimating the effect that specific upward and downward changes in
interest rates would have on pre-tax net interest income. Key assumptions used
in this model include prepayment speeds on mortgage related assets; changes in
market conditions, loan volumes and pricing; and management's determination of
core deposit sensitivity. These assumptions are inherently uncertain and, as a
result, the model can not precisely predict the impact of higher or lower
interest rates on net interest income. Actual results will differ from simulated
results due to timing, magnitude and frequency of interest rate changes and
changes in other market conditions.

Based on the June 30, 2006 simulation, the Company is in an almost neutral
position. Based on the position of the balance sheet and management's
assumptions concerning core deposit sensitivity and other assumptions, net
interest income is forecasted to increase slightly whether rates rise or fall.
Please refer to the corresponding discussion in the Company's Annual Report on
Form 10-K for the year ended December 31, 2005 for more detailed information.

ITEM 4: CONTROLS AND PROCEDURES

      (a) Disclosure controls and procedures. We evaluated the effectiveness of
the design and operation of our disclosure controls and procedures as of June
30, 2006. Our disclosure controls and procedures are the controls and other
procedures that we designed to ensure that we record, process, summarize and
report in a timely manner, the information we must disclose in reports that we
file with, or submit to the SEC. Robert L. Cole, our President and Chief
Executive Officer, and David A. Wilson, our Senior Vice President and Chief
Financial Officer, reviewed and participated in this evaluation. Based on this
evaluation, Messrs. Cole and Wilson concluded that, as of the date of their
evaluation, our disclosure controls were effective.

      (b) Internal controls. There have not been any significant changes in our
internal accounting controls or in other factors that could significantly affect
those controls during the quarter ended June 30, 2006.

PART II. OTHER INFORMATION

      ITEM 1. LEGAL PROCEEDINGS
