# Report of Independent
Registered Public Accounting Firm

The Trustees Mid America
Bank, fsb      Employees
Profit Sharing Plan:

We have audited the accompanying
statements of net assets available for plan benefits of the Mid America Bank, fsb
Employees Profit Sharing Plan (the Plan) as of December 31, 2005 and 2004, and the
related statements of changes in net assets available for plan benefits for each of the
years in the three-year period ended December 31, 2005. These financial statements are the
responsibility of the Plans administrator. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance
with the standards of the Public Company Accounting Oversight Board (United States). 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 the Plans administrator, 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 financial
statements referred to above present fairly, in all material respects, the net assets
available for plan benefits of the Mid America Bank, fsb Employees Profit Sharing
Plan as of December 31, 2005 and 2004, and the changes in net assets available for plan
benefits for each of the years in the three-year period ended December 31, 2005, in
conformity with U.S. generally accepted accounting principles.

Our audits were performed for the
purpose of forming an opinion on the basic financial statements taken as a whole. The
supplemental schedules of assets (held at end of year) as of December 31, 2005 and
reportable transactions for the year ended December 31, 2005, are presented for the
purpose of additional analysis and are not a required part of the basic financial
statements, but are supplementary information required by the Department of Labors
Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. These supplemental schedules are the responsibility of the
Plans administrator, and have been subjected to the auditing procedures applied in the
audits of the basic financial statements and, in our opinion, are fairly stated in all
material respects in relation to the basic financial statements taken as a whole.

| |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Transfers

into the Plan. Transfers from the Companys ESOP to the Plan totaled $55,129 in 2005
and $335,044 in 2004. There were no transfers in 2003.
| |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Contributions

| |  | Each year, the Plan participants may contribute up to 10% of their annual compensation as a
voluntary after-tax contribution. In addition, all employees are allowed to defer up to
75% of their pre-tax compensation as 401(k) contributions up to an annual limit of $14,000
in 2005 ($13,000 in 2004 and $12,000 in 2003). Beginning in 2002, special provisions
applied to employees over the age of 50, which increased the annual limit to $18,000 in
2005 ($16,000 in 2004 and $14,000 in 2003). The Company will make matching contributions
equal to 35% of a participants pre-tax deferral amounts, up to maximum match of
$1,200, for those 401(k) plan participants eligible to receive employer matching
contributions. The Company, at its discretion, may make additional contributions.

Participant
Accounts

| |  | Each participants contribution account is credited with the participants
contribution and an allocation of earnings. Each participants Company contribution
account is also credited with an allocation of the Companys contribution and
forfeitures of terminated participants nonvested balances, subject to federal rules
governing employer contributions to qualified plans. Allocation of the Companys
contribution and forfeitures of terminated participants accounts are based on the
ratio that each participants eligible compensation for the Plan year bears to the
total eligible compensation of all participants for the Plan year. The benefit to which a
participant is entitled is the benefit that can be provided from the participants
accounts. During 2005, 2004 and 2003, non-vested amounts from participants matching
or discretionary Company contributions that were forfeited totaled $110,667, $96,931 and
$71,177, respectively, which were allocated to the remaining participants accounts.

Vesting

| |  | Participants are immediately vested in their pre-tax employee contributions, their after-tax employee
contributions, rollover contributions and merged plan accounts plus actual earnings
thereon. Vesting in the employer matching and employer discretionary contribution accounts
is based on years of service as follows: Less than 2 years  0%; 2 years  20%;
3 years  40%; 4 years  60%; 5 years  80%; 6 years or more  100%.

(2)    
Summary of Significant Accounting Policies

Basis
of Presentation

The
accompanying financial statements have been prepared using the accrual basis of
accounting.

Use
of Estimates

| |  | The preparation of financial statements in conformity with U.S. generally accepted accounting
principles requires the Plans administrator to make estimates and assumptions that
affect the reported amounts of assets and liabilities and changes therein, and disclosure
of contingent assets and liabilities. Actual results could differ from those estimates.
| |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Investments

| |  | Investments in mutual funds, collective trust funds and common stock are stated at fair value as
determined by reference to quoted market prices. The cash liquidity fund and participant
loans receivable are stated at face value plus accrued interest, which approximates fair value. Purchases and sales of investments are recorded on a trade-date basis. Realized
gains and losses on sales are computed using the specific identification method for the
individual asset. Dividend income is recorded on the ex-dividend date. Interest income is
accrued when earned.
| |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | The change in the difference between fair value and the cost of investments for each year is
reflected in the statement of changes in net assets available for plan benefits as
unrealized appreciation or depreciation in fair value of investments.
| |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(3)    
Income Taxes

| |  | The Internal Revenue Service has determined and informed the Company by a letter dated July
18, 2002 that the Plan and related trust are designed in accordance with applicable
sections of the Internal Revenue Code (IRC). Although the Plan has been amended since
receiving the determination letter, the Plan administrator believes that the Plan is
designed and is currently being operated in compliance with the applicable requirements of
the IRC.
| |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(4)    
Administrative Expenses

The
Company generally pays the administrative expenses of the Plan.

(5)    
Plan Termination

| |  | Although it has not expressed any intent to do so, the Company has the right under the Plan
agreement to discontinue its contributions at any time and to terminate the Plan subject
to the provisions of ERISA. In the event of Plan termination, participants will become
100% vested in their accounts.

(8)    
Risks and Uncertainties

| |  | Plan investments are exposed to various risks such as interest rate, market and credit risks.
Due to the level of risk associated with certain investments, it is at least reasonably
possible that changes in the values of investments will occur in the near term and that
such changes could materially affect participants account balances and the amounts
reported in the statements of net assets available for plan benefits.
