Subsidiaries  Notes to Consolidated Financial Statements  (Unaudited)

# Note 1  Basis of
Presentation and Consolidation

TierOne
Corporation (Company) is a Wisconsin corporation headquartered in Lincoln,
Nebraska. TierOne Corporation is the holding company for TierOne Bank (Bank).
The Bank has two wholly owned subsidiaries, TMS Corporation of the Americas
(TMS) and United Farm & Ranch Management, Inc. (UFARM). TMS is
the holding company of TierOne Investments and Insurance, Inc. (d/b/a TierOne Financial),
a wholly owned subsidiary that administers the sale of securities and insurance products,
and TierOne Reinsurance Company, a wholly owned subsidiary that reinsures credit life and
disability insurance policies. UFARM provides agricultural customers with professional
farm and ranch management and real estate brokerage services. The accompanying unaudited
consolidated financial statements include the accounts of the Bank and its wholly owned
subsidiaries.

The
assets of the Company, on an unconsolidated basis, primarily consist of 100% of the
Banks common stock. The Company has no significant independent source of income and
therefore depends on cash distributions from the Bank to meet its funding requirements.

The
accompanying interim consolidated financial statements as of March 31, 2007 and for the
three months ended March 31, 2007 and 2006 are unaudited. All significant intercompany
accounts and transactions have been eliminated in consolidation. In the opinion of
management, the accompanying unaudited consolidated financial statements contain all
adjustments (consisting of normal recurring accruals) considered necessary for a fair
presentation of the financial position and operating results for interim periods. The
unaudited consolidated financial statements have been prepared in accordance with U.S.
generally accepted accounting principles (GAAP) for interim financial
information, in accordance with instructions to Form 10-Q and Article 10 of Regulation S-X
promulgated by the Securities and Exchange Commission (SEC), and do not
include all of the information and notes required for complete, audited financial
statements. The unaudited consolidated financial statements should be read in conjunction
with the audited consolidated financial statements and notes thereto included in our
Annual Report on Form 10-K for the year ended December 31, 2006. The results of operations
for the three months ended March 31, 2007 are not necessarily indicative of the results
which may be expected for the entire calendar year 2007.

As
used in this report, unless the context otherwise requires, the terms we,
us, or our refer to the Company and the Bank.

# Note 2  Critical
Accounting Policies

Various
elements of our accounting policies, by nature, are inherently subject to estimation
techniques, valuation assumptions and other subjective assessments. Our policies with
respect to the methodologies used to recognize income, determine the allowance for loan
losses, evaluating investment and mortgage-backed securities for impairment, evaluating
goodwill and other intangible assets, valuation of mortgage servicing rights, valuation
and measurement of derivatives and commitments, valuation of real estate owned and income
taxes are our most critical accounting policies. These policies are important to the
presentation of our financial condition and results of operations, involve a higher degree
of complexity and require management to make difficult and subjective judgments which
often require assumptions or estimates about highly uncertain matters. The use of
different judgments, assumptions and estimates could result in material differences in our
reported financial condition and results of operations. The following discussion regarding
our critical accounting policies should be read in conjunction with our 2006 Annual Report
on Form 10-K.

Allowance
for Loan Losses. We have identified the allowance for loan losses as a
critical accounting policy where amounts are subject to material variation. This policy is
significantly affected by our judgment and uncertainties and there is a likelihood that
materially different amounts could be reported under different, but reasonably plausible,
conditions or assumptions. The allowance for loan losses is considered a critical
accounting estimate because there is a large degree of judgment in:

| |  | Assigning
individual loans to specific risk levels (pass, special mention, substandard, doubtful
and loss);
| | - | -----------------------------------------------------------------------------------------------------------

| |  | Valuing
the underlying collateral securing the loans;
| | - | -----------------------------------------------------

| |  | Determining
the appropriate reserve factor to be applied to specific risk levels for special mention
loans and those adversely classified (substandard, doubtful and loss); and
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | Determining
reserve factors to be applied to pass loans based upon loan type.
| | - | -----------------------------------------------------------------------------

We
establish provisions for loan losses, which are charges to our operating results, in order
to maintain a level of total allowance for loan losses that, in managements belief,
covers all known and inherent losses that are both probable and reasonably estimable at
each reporting date. Management reviews the loan portfolio no less frequently than
quarterly in order to identify those inherent losses and to assess the overall collection
probability of the loan portfolio. Managements review includes a quantitative
analysis by loan category, using historical loss experience, classifying loans pursuant to
a grading system and consideration of a series of qualitative loss factors. The evaluation
process includes, among other things:

| |  | Assigning
individual loans to specific risk levels (pass, special mention, substandard, doubtful
and loss);
| | - | -----------------------------------------------------------------------------------------------------------

| |  | Trends
and levels of delinquent, nonperforming or "impaired" loans;
| | - | -------------------------------------------------------------------

| |  | Trends
and levels of charge-offs and recoveries;
| | - | ------------------------------------------------

TierOne Corporation and
Subsidiaries  Notes to Consolidated Financial Statements  (Unaudited)

| |  | Underwriting
terms or guarantees for loans;
| | - | -------------------------------------------

| |  | Impact
of changes in underwriting standards, risk tolerances or other changes in lending
practices;
| | - | ---------------------------------------------------------------------------------------------------

| |  | Changes
in the value of collateral securing loans;
| | - | --------------------------------------------------

| |  | Total
loans outstanding and the volume of loan originations;
| | - | ------------------------------------------------------------

| |  | Type,
size, terms and geographic concentration of loans held;
| | - | -------------------------------------------------------------

| |  | Changes
in qualifications or experience of the lending staff;
| | - | -------------------------------------------------------------

| |  | Changes
in local or national economic or industry conditions;
| | - | -------------------------------------------------------------

| |  | Number
of loans requiring heightened management oversight;
| | - | ----------------------------------------------------------

| |  | Changes
in credit concentration; and
| | - | ------------------------------------

| |  | Changes
in regulatory requirements.
| | - | -----------------------------------

This
evaluation is inherently subjective as it requires estimates that are susceptible to
significant revision as more information becomes available or as future events occur.

The
allowance for loan losses has two elements. The first element is an allocated allowance
established for specific loans identified by the credit review function that are evaluated
individually for impairment and are considered to be impaired. A loan is considered
impaired when, based on current information and events, it is probable that we will be
unable to collect the scheduled payments of principal and interest when due according to
the contractual terms of the loan agreement. Impairment is measured by:

| |  | The
fair value of the collateral if the loan is collateral dependent;
| | - | ---------------------------------------------------------------------

| |  | The
present value of expected future cash flows; or
| | - | ---------------------------------------------------

| |  | The
loans observable market price.
| | - | -----------------------------------

The second element is an estimated
allowance established for losses which are probable and reasonable to estimate on each
category of outstanding loans. While management uses available information to recognize
probable losses on loans inherent in the portfolio, future additions to the allowance may
be necessary based on changes in economic conditions and other factors. In addition,
various regulatory agencies, as an integral part of their examination process,
periodically review our allowance for loan losses. Such agencies may require us to
recognize additions to the allowance based on their judgment of information available to
them at the time of their examination.

Mortgage
Servicing Rights.  On January 1, 2007 we adopted Statement of Financial Accounting Standard (SFAS) No. 156, Accounting
for Servicing of Financial Assets  an Amendment of FASB Statement No. 140(SFAS No. 156). In accordance with SFAS No. 156, we have elected to
continue to utilize the amortization method for all of our mortgage servicing right
assets, thus, carrying our mortgage servicing rights at the lower of cost or
market (fair value). Under the amortization method, we amortize mortgage servicing
rights in proportion to and over the period of net servicing income. Income generated as a
result of new servicing assets is reported as net gain on sale of loans in the
Consolidated Statements of Income. Loan servicing fees, net of amortization of mortgage
servicing rights, is recorded in fees and service charges in the Consolidated Statements of
Income.

TierOne Corporation and
Subsidiaries  Notes to Consolidated Financial Statements  (Unaudited)

We
capitalize the estimated value of mortgage servicing rights upon the sale of loans. The
estimated value takes into consideration contractually known amounts, such as loan
balance, term and interest rate. These estimates are impacted by loan prepayment speeds,
servicing costs and discount rates used to compute a present value of the cash flow
stream. We evaluate the fair value of mortgage servicing rights on a quarterly basis using
current prepayment speed, cash flow and discount rate estimates. Changes in these
estimates impact fair value and could require us to record a valuation allowance or
recovery. The fair value of mortgage servicing rights is highly sensitive to changes in
assumptions. Changes in prepayment speed assumptions have the most significant impact on
the fair value of mortgage servicing rights. Generally, as interest rates decline,
prepayments accelerate with increased refinance activity, which results in a decrease in
the fair value of mortgage servicing rights. As interest rates rise, prepayments generally
slow, which results in an increase in the fair value of mortgage servicing rights. All
assumptions are reviewed for reasonableness on a quarterly basis and adjusted as necessary
to reflect current and anticipated market conditions. Thus, any measurement of fair value
is limited by the conditions existing and the assumptions utilized as of a particular
point in time, and those assumptions may not be appropriate if applied at a different
point in time. We currently do not utilize direct financial hedges to mitigate the effect
of changes in the fair value of our mortgage servicing rights.

Income
Taxes. We estimate income taxes payable based on the amount we expect to
owe various tax authorities. Accrued income taxes represent the net estimated amount due
to, or to be received from, taxing authorities. In estimating accrued income taxes, we
assess the relative merits and risks of the appropriate tax treatment of transactions,
taking into account the applicable statutory, judicial and regulatory guidance in the
context of our tax position. Although we utilize current information to record income
taxes, underlying assumptions may change over time as a result of unanticipated events or
circumstances.

We
utilize estimates of future earnings to support our position that the benefit of our
deferred tax assets will be realized. If future pre-tax income should prove nonexistent or
less than the amount of temporary differences giving rise to the net deferred tax assets
within the tax years to which they may be applied, the assets will not be realized and our
net income will be adversely affected.

# Note 3  Earnings
Per Share

Basic
earnings per share (EPS) is computed by dividing net income by the weighted
average number of common shares outstanding for the period. Diluted earnings per share
reflects the potential dilution that could occur if securities or other contracts to issue
common stock were exercised. Diluted earnings per share is computed after giving
consideration to the weighted average dilutive effect of our 2003 Stock Option Plan shares
and 2003 Management Recognition and Retention Plan shares. The following table is a
reconciliation of basic and diluted EPS:

# Note 4 
Stock-Based Benefit Plans

General.          We
account for our stock-based benefit plans using SFAS No. 123(R), Share-Based
          Payment (SFAS No. 123(R)). SFAS No. 123(R) requires that compensation expense
          related to stock-based payment transactions be recognized in the financial
          statements and that expense be measured based on the fair value of the equity
or           liability instrument issued. SFAS No. 123(R) also requires that forfeitures
be           estimated over the vesting period of the instrument.

Stock-Based
Employee Compensation Expense. Amounts recognized in the financial
statements with respect to our Employee Stock Ownership Plan (ESOP) and
stock-based employee compensation plans are presented in the following table:

|                                                  | Three Months Ended March 31,

|                                                 
|Amount of related income tax benefit recognized   |                             
|                                                 

Employee
Stock Ownership Plan.Concurrent with the conversion from mutual to stock
ownership, we established an ESOP for the benefit of our employees. The ESOP is a
qualified pension plan under Internal Revenue Service guidelines that covers all full-time
employees who have completed 1,000 hours of service. Upon formation, the ESOP
purchased 1,806,006 shares of common stock issued in the initial public offering with the
proceeds of an $18,060,060 loan from the Company.

We
account for our ESOP in accordance with Statement of Position 93-6, Employers
Accounting for Employee Stock Ownership Plans. Accordingly, expense is recognized
based on the market value (average stock price) of shares scheduled to be released from
the ESOP trust. The excess fair value of ESOP shares over cost is recorded as compensation
expense but is not deductible for tax purposes. As shares are committed to be released
from collateral, we report compensation expense equal to the average market price of the
shares and the shares become outstanding for EPS computations. Our contributions and
dividends on allocated and unallocated ESOP shares are used to pay down the loan.
Accordingly, we have recorded the obligation with an offsetting amount of unearned
compensation in stockholders equity in the accompanying Consolidated Statements of
Financial Condition.

Management
Recognition and Retention Plan. We established the 2003 Management
Recognition and Retention Plan (MRRP) which is a stock-based incentive plan.
The shares awarded by the MRRP vest to participants at the rate of 20% per year.
Compensation expense for this plan is being recorded over a 60-month period, using the
straight-line amortization method adjusted for forfeitures, and is based on the market
value of our stock as of the date the awards were made. Stockholders approved 903,003
shares to be granted under the MRRP and 100,653 shares are still available for future
grants as of March 31, 2007. The following table summarizes shares of our common stock
that were subject to award and have been granted pursuant to the MRRP as of March 31,
2007:

Compensation
expense related to the MRRP totaled $726,000 for the three months ended March 31, 2007 and
2006. The weighted average grant date fair value of shares awarded by the MRRP was $18.27
and $18.21 at March 31, 2007 and 2006, respectively. As of March 31, 2007, we had $3.4
million of total unrecognized employee compensation expense related to unvested MRRP
shares which are expected to be recognized over a weighted average period of 1.3 years.
There were no MRRP shares granted, vested or forfeited during the three months ended March
31, 2007. We realized excess tax benefits related to MRRP shares of $8,000 during the
three months ended March 31, 2007.

Stock Option Plan. We established the 2003 Stock Option Plan
(SOP) under which 2,257,508 shares of our common stock were reserved for the
grant of stock options to directors, officers and employees. Stock options awarded under
the SOP vest to participants at the rate of 20% per year. Compensation expense for this
plan is being recorded over a 60-month period, using the straight-line amortization method
adjusted for forfeitures, and is based on the fair value of our stock options as of the
date the awards were made. The exercise price of the options is equal to the market price
of the common stock on the grant date. Stockholders approved 2,257,508 stock options to be
granted under the SOP and 359,758 of these stock options remain available for future
grants as of March 31, 2007.

The
fair value of each option was estimated on the date of the grant using the Black-Scholes
model. The dividend yield was calculated based on the annual dividends paid and the
12-month average closing stock price at the time of the grant. Expected volatility was
based on historical volatility of our stock price at the date of grant. We have utilized
historical experience to determine the expected life of the stock options and to estimate
future forfeitures. All inputs into the Black-Scholes model are estimates at the time of
the grant. Actual results in the future could materially differ from these estimates;
however, such results would not impact future reported net income.

# Note 5  Goodwill
and Other Intangible Assets

Goodwill.          Goodwill
represents the excess price paid over the fair value of the tangible           and
intangible assets and liabilities acquired in connection with the           acquisition
of United Nebraska Financial Co. (UNFC) in 2004. There was no goodwill recorded in connection with           our Marine
Bank branch purchase in 2006. We evaluate goodwill for impairment           annually in
accordance with SFAS No. 142, Goodwill and Other Intangible           Assets.
There have been no changes in the carrying amount of goodwill during           the three
months ended March 31, 2007 due to impairment as we are not aware of           any facts
or circumstances that would indicate our carrying value exceeded fair           value.
The changes in the carrying amount of goodwill for the three months ended           March
31, 2007 and 2006 are as follows:

|                                                         | Three Months Ended

|                                                        

Other
Intangible Assets. Our only identifiable other intangible asset is the
value of core deposits acquired as part of the UNFC and Marine Bank transactions. The core
deposit intangible assets have been estimated to have nine- to ten-year lives. Core
deposit intangible assets are amortized using an accelerated method of amortization which
is recorded in other operating expense.

We
believe all unrealized losses as of March 31, 2007 to be market related, with no permanent
sector or issuer credit concerns or impairments. We had 102 securities with unrealized
losses totaling $832,000 for 12 consecutive months or longer as of March 31, 2007. The
unrealized losses are believed to be temporarily, not permanently, impaired in value.
Impairment is deemed temporary if the positive evidence indicating that an
investments carrying amount is recoverable within a reasonable time period outweighs
negative evidence to the contrary. At March 31, 2007, we have the ability and intent to
hold these securities until maturity.

related to loan concentrations and monitoring such concentrations to limit potential loss
exposure. At March 31, 2007 and December 31, 2006, approximately 20.3% and 20.8%,
respectively, of total loans were secured by properties or made to individuals located

At
March 31, 2007, our nonperforming residential construction loans totaled $29.9 million of
which $24.7 million were located in Florida. Approximately $19.5 million of our
nonperforming residential construction loans were located in the Cape Coral
area of Lee County in Florida. As disclosed in our December 31, 2006 earnings release and
Annual Report on Form 10-K, we reported that we had a group of residential construction
loans located in the Cape Coral area of southwest Florida. These loans, made to individual
homebuyers wishing to build a second or retirement home in the Cape Coral area, are for
properties located in a fully platted, zoned and infrastructure-complete housing
development with direct waterfront access for many lots.

To
limit geographic loan concentration, we discontinued purchasing residential construction
loans in the Cape Coral area from a local Florida-based mortgage brokerage firm by
December 31, 2005. At March 31, 2006, we had 874 residential construction loan commitments
totaling $233.2 million in the Cape Coral area with disbursed funds amounting to $110.0
million. Each borrower in the Cape Coral area possessed a strong credit score which met
Fannie Mae or other secondary market underwriting guidelines (average FICO score for Cape
Coral area borrowers was 741 at March 31, 2007) and had also obtained a contractual
commitment for permanent financing with third-party lenders upon completion of the
residence. At March 31, 2006, only one loan of $360,000 was 90 or more days delinquent.

A
substantially higher than expected surge in residential construction building permit
applications occurred in the Cape Coral area in early to mid-2006 which resulted in
unusual delays in the commencement of construction. In many cases, these delays extended
beyond the original term of the residential construction loans. The backlog of residential
construction permits has returned to normal levels and as a result, several residential
construction builders are actively constructing homes for our borrowers.

Notwithstanding
localized construction delays and a correction of housing values in selected Florida
markets, we have reduced our Cape Coral residential construction loan commitments by 37.9% from
March 31, 2006 to $144.9 million at December 31, 2006 and total disbursed amounts
outstanding declined by 23.5% during the same period to $84.2 million.

We
have taken a number of aggressive, pro-active steps designed to address our Florida
residential construction loan delinquencies. These measures include offering loan and lot
modification loans to qualified borrowers; identifying large, highly-respected local
builders to construct homes at 2006 price levels; and finding other third-party lenders who
will offer permanent financing and closing cost incentives to borrowers for completed
homes. We have also reclaimed servicing functions on a number of loans from the Florida
mortgage broker, required the broker to engage new legal counsel to handle foreclosure
matters and entered into various loss-sharing agreements with the Florida mortgage broker.
Through March 31, 2007, we have not charged-off any Cape Coral area residential
construction loan balances. We plan to aggressively pursue all legal remedies available to
us against any delinquent Florida borrower.

Residential
construction loan commitments in the Cape Coral area declined 17.3% to $119.9 million at
March 31, 2007 compared to $144.9 million at December 31, 2006. Disbursed funds associated
with these loans declined 13.3% to $72.9 million at March 31, 2007, compared to
$84.2 million at December 31, 2006, and represented less than 2.4% of our net loans.

We
believe that, based on information currently available to us, our allowance
for loan losses is maintained at a level which covers all known and inherent losses that
are both probable and reasonable to estimate at the present time. Actual losses are
dependent upon future events and, as such, further changes to the level of allowance for
loan losses may become necessary based on changes in economic conditions and other
factors.

# Note 8  Mortgage
Servicing Rights

On
January 1, 2007, we adopted SFAS No. 156, Accounting for Servicing of Financial Assets
 an Amendment of FASB Statement No. 140(SFAS No. 156). In
accordance with SFAS No. 156, we have elected to continue to utilize the amortization
method for all of our mortgage servicing right assets, thus, carrying our mortgage
servicing rights at the lower of cost or market (fair value). Under the
amortization method, we amortize mortgage servicing rights in proportion to and over the
period of net servicing income. Income generated as a result of new servicing assets is
reported as net gain on sale of loans in the Consolidated Statements of Income. Loan
servicing fees, net of amortization of mortgage servicing rights, is recorded in fees and
service charges in the Consolidated Statements of Income.

We
primarily service one-to-four family residential mortgage loans that comprise a single
class of servicing assets. We obtain mortgage servicing right assets when we deliver
loans, both originated and purchased, as an agent into the secondary market on
a servicing-retained basis. Initial fair value of the servicing right is calculated by a
discounted cash flow model based on market value assumptions at the time of origination.

The
balance of mortgage servicing rights, net of valuation allowances, at both March 31, 2007 and
December 31, 2006 was $12.5 million. The fair values of these rights were
approximately $15.8 million and $15.3 million at March 31, 2007 and December 31, 2006,
respectively. The following are the key assumptions used in measuring the fair values of
capitalized mortgage servicing rights and the sensitivity of the fair values to changes in
those assumptions:

|(Dollars in thousands)             | March 31, 2007 | December 31, 2006
|---------------------------------- | -------------- | -----------------
|Serviced loan portfolio balance    | $1,310,808     | $1,295,418       
|Fair value                         | $15,786        | $15,276          
|Prepayment speed                   | 6.30% - 31.47% | 8.64% - 46.44%   
|Weighted average prepayment speed  | 11.81%         | 14.40%           
|Fair value with 10% adverse change | $15,151        | $14,654          
|Fair value with 20% adverse change | $14,522        | $14,034          
|Discount rate                      | 9.50% - 13.00% | 10.00% - 14.00%  
|Weighted average discount rate     | 10.99%         | 11.34%           
|Fair value with 10% adverse change | $15,202        | $14,806          
|Fair value with 20% adverse change | $14,432        | $14,325          
|                                  

The
sensitivity of the fair values is hypothetical and should be used with caution. As the
figures indicate, changes in fair value based on a variation in assumptions generally
cannot be extrapolated because the relationship of the change in assumptions to the change
in fair value may not be linear. Also, in the table, the effect of a variation in a
particular assumption on the fair value of the mortgage servicing rights is calculated
without changing any other assumption. In reality, changes in one assumption may result in
changes in another that might magnify or counteract the sensitivities.

Mortgage
Servicing Right Activity. The following table summarizes mortgage servicing
right activity including amortization expense:

|Mortgage servicing rights capitalized |                             
|Amortization expense                  |                             
|Valuation adjustment                  |

|                                     

Mortgage
Servicing Right Valuation Allowance. We evaluate the fair value of mortgage
servicing rights on a quarterly basis using current prepayment speeds, cash flow and
discount rate estimates. Changes in these estimates impact fair value and could require us
to record a valuation allowance or recovery. Our evaluation of mortgage servicing rights
at March 31, 2007 indicated that a valuation allowance of $23,000 was necessary. At March
31, 2006, our analysis of mortgage servicing rights indicated a valuation allowance was
not necessary. The amortization expense and valuation adjustment are recorded as a
reduction of fees and service charges in the accompanying Consolidated Statements of
Income.

The
convertible fixed-rate notes are convertible to adjustable-rate notes at the option of the
FHLBank Topeka (FHLBank). The line of credit with the FHLBank expires in
November 2007. We expect the line of credit agreement to be renewed in the ordinary course
of business due to our current blanket collateral agreement with the FHLBank.

residential construction, commercial construction and agricultural real estate loans.
Under our blanket collateral agreement with the FHLBank, our borrowing capacity at March
31, 2007 was $948.1 million. Other qualifying collateral can be pledged in the event
additional borrowing capacity is required.

Our
retail repurchase agreements are primarily collateralized by U.S. Government and agency

# Note 11 
Unrecognized Tax Benefits

In
June 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation No. 48, Accounting for Uncertainty in Income Taxes  an
Interpretation of FASB Statement No. 109 (FIN 48). FIN 48 requires that we
determine whether a tax position is more likely than not to be sustained upon examination,
including resolution of any related appeals or litigation processes, based on the
technical merits of the position. Once it is determined that a position meets the
recognition threshold, the position is measured to determine the amount of benefit to be
recognized in the financial statements.

We
adopted FIN 48 on January 1, 2007 and, as a result, recognized no material adjustment in
our liability for unrecognized tax benefits. Unrecognized tax benefits, excluding interest
and penalties, were $2.8 million at March 31, 2007. Unrecognized tax benefits of $118,000
and interest and penalties of $270,000 would favorably affect our effective tax rate if
recognized in future periods. Unrecognized tax benefits of $601,000 are related to our
UNFC acquisition and would reduce goodwill if recognized in future periods. The following
table summarizes our unrecognized tax benefits upon adoption and for the three months
ended March 31, 2007:

|(Dollars in thousands)                                                         | Unrecognized Tax Benefits
|------------------------------------------------------------------------------ | -------------------------
|Unrecognized tax benefits at January 1, 2007                                   |                          
|Changes in unrecognized tax benefits from current or prior year tax positions  |                          
|Changes in unrecognized tax benefits from settlements with taxing authorities  |                          
|Changes in unrecognized tax benefits from the lapse of statutes of limitations |                          
|                                                                              
|Unrecognized tax benefits at March 31, 2007                                    |                          
|                                                                              

We
recognize interest and penalties related to uncertain tax positions in income tax expense
in the Consolidated Statements of Income. We did not record any expense related to tax
interest and penalties during the three months ended March 31, 2007. At March 31, 2007, we
had approximately $270,000 of accrued interest payable related to uncertain tax positions
recorded in our Consolidated Statements of Financial Position.

We
anticipate that a reduction in unrecognized tax benefits of up to $2.2 million is reasonably
possible during the next 12 months. This reduction will be principally due to a change in
accounting method related to the timing of when certain deferred loan fees are recognized
for tax purposes if approved by the Internal Revenue Service.

The
tax years of 2003 through 2006 remain open for examination by federal and state taxing authorities.

# Note 12  Current
Accounting Pronouncements

For
a discussion regarding accounting pronouncements, interpretations, exposure drafts and
other formal accounting guidance and the impact of these on our financial condition and
results of operations, reference is made to our Annual Report on Form 10-K for the year
ended December 31, 2006. The following discussion identifies certain recently issued
accounting guidance.

# Statements of Financial
Accounting Standards

In
September 2006, the FASB issued SFAS No. 157, Fair Value Measurements(SFAS
No. 157). SFAS No. 157 defines fair value, establishes a framework for measuring
fair value under generally accepted accounting principles and expands disclosure about
fair value measurements. SFAS No. 157 emphasizes that fair value is a market-based
measurement, not an entity-specific measurement. Therefore, a fair value measurement
should be determined based on the assumptions that market participants would use in
pricing the asset or liability. This statement clarifies that market participant
assumptions include assumptions about risk. A fair value measurement should include an
adjustment for risk if market participants would include one in pricing the related asset
or liability, even if the adjustment is difficult to determine. This statement also
clarifies that market participant assumptions should also include assumptions about the
effect of a restriction on the sale or use of an asset. This statement clarifies that fair
value measurement for a liability should reflect nonperformance risk (the risk that the
obligation will not be fulfilled). This statement expands disclosures about the use of
fair value to measure assets and liabilities in interim and annual periods subsequent to
initial recognition. The disclosures focus on the inputs used to measure fair value and
for recurring fair value measurements using significant unobservable inputs and the effect
of the measurements on earnings (or changes in net assets) for the period. SFAS No. 157 is
effective for financial statements issued for fiscal years beginning after November 15,
2007. We are evaluating the impact that SFAS No. 157 may have on our consolidated
financial statements.

In
February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets
and Financial Liabilities, Including an amendment of FASB Statement No. 115
(SFAS No. 159). SFAS No. 159 provides an alternative measurement treatment for
certain financial assets and liabilities, under an instrument-by-instrument election, that
permits fair value to be used for both initial and subsequent measurement, with changes in
fair value recognized in earnings. SFAS No. 159 is effective for fiscal years beginning after
November 15, 2007. We are evaluating the impact that SFAS No. 159 may have on our
consolidated financial statements.

# Item 2 - Managements
Discussion and Analysis of Financial Condition and Results of      Operations.

# General

TierOne
Bank (Bank), a subsidiary of TierOne Corporation (Company), is a
$3.4 billion federally chartered stock savings bank headquartered in Lincoln, Nebraska.
Established in 1907, the Bank offers customers a wide variety of full-service consumer,
commercial and agricultural banking products and services through a network of 69 banking
offices located in Nebraska, Iowa and Kansas and nine loan production offices located in
Arizona, Colorado, Florida, Minnesota, Nevada and North Carolina. Product offerings
include residential, commercial and agricultural real estate loans; consumer,
construction, business and agricultural operating loans; warehouse mortgage lines of
credit; consumer and business checking and savings plans; investment and insurance
services; and telephone and internet banking.

Our
results of operations are dependent primarily on net interest income, which is the
difference between the interest earned on our assets, primarily our loan and securities
portfolios, and our cost of funds, which consists of the interest paid on our deposits and
borrowings. Our net income is also affected by our provision for loan losses, noninterest
income, noninterest expense and income tax expense. Noninterest income generally includes
fees and service charges, debit card fees, net income from real estate operations, net
gain on sales of investment securities, loans held for sale and real estate owned and
other operating income. Noninterest expense consists of salaries and employee benefits,
occupancy, data processing, advertising and other operating expense. Our earnings are
significantly affected by general economic and competitive conditions, particularly
changes in market interest rates and U.S. Treasury yield curves, governmental policies and
actions of regulatory authorities.

As
used in this report, unless the context otherwise requires, the terms we,
us, or our refer to the Company and the Bank.

# Comparison of Financial
Condition at March 31, 2007 and December 31, 2006

# Assets

General.          Our
total assets were $3.4 billion at March 31, 2007, an increase of $10.1           million,
or 0.3%, compared to December 31, 2006.

Investment
Securities. Our available for sale investment securities totaled $121.2
million at March 31, 2007, an increase of $16.2 million, or 15.5%, compared to $105.0
million at December 31, 2006. During the three months ended March 31, 2007 we had security
purchases of $41.8 million which were partially offset by $25.9 million in proceeds from
maturing and sold investment securities. The securities purchased during 2007 were
primarily U.S. Treasury securities that were purchased to collateralize deposits.

Mortgage-Backed
Securities. Our mortgage-backed securities, all of which are recorded as
available for sale, totaled $10.7 million at March 31, 2007, a decrease of $1.6 million,
or 12.6%, compared to $12.3 million at December 31, 2006. The decrease in our
mortgage-backed securities was the result of $1.6 million of principal payments received
during the three months ended March 31, 2007.

Loans
Receivable. Net loans totaled $3.0 billion at March 31, 2007 and remained
relatively unchanged compared to December 31, 2006. During the three months ended March
31, 2007, we originated $389.0 million of loans (exclusive of warehouse mortgage lines of
credit) and purchased $115.8 million of loans. These increases were partially offset by
$497.0 million of principal repayments and $58.6 million of loan sales. The following
table details the composition of our loan portfolio at the dates indicated:

The
increase in our commercial construction loan portfolio was primarily attributable to two
loans originated totaling $37.2 million during the three months ended March 31, 2007. The
decline in our residential construction loan portfolio was primarily attributable to a
reduction in the volume of loans we purchased from mortgage brokers in order to manage loan
concentrations in certain areas of the United States. The changes in the remainder of our
loan portfolio were attributable to loan repayments and prepayments and loan refinancing
activity.

Allowance
for Loan Losses. Our allowance for loan losses increased $777,000, or 2.4%,
to $33.9 million at March 31, 2007 compared to $33.1 million at December 31, 2006. During
the three months ended March 31, 2007 we recorded provisions for loan losses totaling $1.5
million and net-charge-offs of $691,000. Our allowance for loan losses as a percentage of
nonperforming loans was 84.16% at March 31, 2007 compared to 110.25% at December 31, 2006.
Our ratio of the allowance for loan losses to net loans was 1.11% and 1.09% at March 31,
2007 and December 31, 2006, respectively.

Nonperforming
loans increased $10.2 million, or 34.1%, to $40.3 million at March 31, 2007 compared to
$30.1 million at December 31, 2006. The increase in nonperforming loans at March 31, 2007
was primarily attributable to residential construction loans. We anticipate that the level
of loan delinquencies may continue to increase for the foreseeable future.

As
disclosed in our December 31, 2006 earnings release and Annual Report on Form 10-K, we
reported that we had a group of residential construction loans located in the Cape Coral
area of southwest Florida. These loans, made to individual homebuyers wishing to build a
second or retirement home in the Cape Coral area, are for properties located in a fully
platted, zoned and infrastructure-complete housing development with direct waterfront
access for many lots.

To
limit geographic loan concentration, we discontinued purchasing residential construction
loans in the Cape Coral area from a local Florida-based mortgage brokerage firm by
December 31, 2005. At March 31, 2006, we had 874 residential construction loan commitments
totaling $233.2 million in the Cape Coral area with disbursed funds amounting to $110.0
million. Each borrower in the Cape Coral area possessed a strong credit score which met
Fannie Mae or other secondary market underwriting guidelines (average FICO score for the
Cape Coral area borrowers was 741 at March 31, 2007) and had also obtained a contractual
commitment for permanent financing with third-party lenders upon completion of the
residence. At March 31, 2006, only one loan of $360,000 was 90 or more days delinquent.

A
substantially higher than expected surge in residential construction building permit
applications occurred in the Cape Coral area in early to mid-2006 which resulted in
unusual delays in the commencement of construction. In many cases, these delays extended
beyond the original term of the residential construction loans. The backlog of residential
construction permits has returned to normal levels and as a result, several residential
construction builders are actively constructing homes for our borrowers.

Notwithstanding
localized construction delays and a correction of housing values in selected Florida
markets, we have reduced our Cape Coral residential construction loan commitments by 37.9% from
March 31, 2006 to $144.9 million at December 31, 2006 and total disbursed amounts
outstanding declined by 23.5% during the same period to $84.2 million.

We
have taken a number of aggressive, pro-active steps designed to address our Florida
residential construction loan delinquencies. These measures include offering loan and lot
modification loans to qualified borrowers; identifying large, highly-respected local
builders to construct homes at 2006 price levels; and finding other third-party lenders who
will offer permanent financing and closing cost incentives to borrowers for completed
homes. We have also reclaimed servicing functions on a number of loans from the Florida
mortgage broker, required the broker to engage new legal counsel to handle foreclosure
matters and entered into various loss-sharing agreements with the Florida mortgage broker.
Through March 31, 2007, we have not charged-off any Cape Coral area residential
construction loan balances. We plan to aggressively pursue all legal remedies available to
us against any delinquent Florida borrower.

Residential
construction loan commitments in the Cape Coral area declined 17.3% to $119.9 million at
March 31, 2007 compared to $144.9 million at December 31, 2006. Disbursed funds associated
with these loans declined 13.3% to $72.9 million at March 31, 2007, compared to
$84.2 million at December 31, 2006, and represented less than 2.4% of our net loans.

We
believe that, based on information currently available to us, our allowance
for loan losses is maintained at a level which covers all known and inherent losses that
are both probable and reasonable to estimate at the present time. Actual losses are
dependent upon future events and, as such, further changes to the level of allowance for
loan losses may become necessary based on changes in economic conditions and other
factors.

FHLBank

million at March 31, 2007, an increase of $954,000, or 1.5%, compared to $62.0 million at
December 31, 2006. The increase was attributable to FHLBank stock dividends received during

31, 2007, an increase of $40.9 million, or 4.4%, compared to $931.8 million at December
31, 2006. The number of transaction accounts increased by 1,729 accounts, or 1.3%, to
130,329 accounts compared to 128,600 accounts at December 31, 2006. The weighted average
interest rate of our transaction accounts was 1.76% at March 31, 2007 compared to 1.68% at
December 31, 2006. The weighted average interest rate of our time deposits was 4.94% at

totaled $864.3 million at March 31, 2007, a decrease of $98.1 million, or 10.2%, compared
to $962.4 million at December 31, 2006. The decrease in FHLBank advances and other
borrowings at March 31, 2007 was primarily attributable to the utilization of increased
deposits to reduce our FHLBank advances. The weighted average interest rate on FHLBank
advances executed during the three months ended March 31, 2007 was 3.94%. The weighted
average interest rate on FHLBank advances which matured or were called by the FHLBank

Stockholders
Equity. At March 31, 2007, stockholders equity totaled $364.4
million, an increase of $11.1 million, or 3.2%, compared to $353.3 million at December 31,
2006. The increase in stockholders equity primarily reflected net income of $9.4
million during the three months ended March 31, 2007, $1.1 million related to common stock
earned by participants in the Employee Stock Ownership Plan (ESOP), $726,000
related to amortization of awards under the 2003 Management Recognition and Retention Plan
(MRRP) and $420,000 related to amortization of stock options under the 2003
Stock Option Plan (SOP). These increases were partially offset by $1.2 million
in cash dividends paid to our stockholders. We paid cash dividends of $0.07 per common
share on March 30, 2007 to stockholders of record on March 15, 2007.

On
July 27, 2004, we announced that our Board of Directors had authorized the repurchase of
up to 1,828,581 shares of our outstanding common stock. There is no stated expiration date
for this authorization. We did not repurchase any shares of our outstanding common stock
during the three months ended March 31, 2007. After accounting for earlier repurchases, at
March 31, 2007, the total remaining common stock repurchase authority was 1,527,059
shares.

Comparison of Operating Results
for the Three Months Ended March 31, 2007 and 2006

Net
Income. Net income for the three months ended March 31, 2007 was $9.4
million, or $0.55 per diluted share ($0.56 per basic share), compared to net income of
$9.2 million, or $0.54 per diluted share ($0.56 per basic share), for the three months
ended March 31, 2006.

Net
Interest Income. Net interest income is the most significant component of
our earnings and consists of interest income on interest-earning assets offset by interest
expense on interest-bearing liabilities. Changes in net interest income result from
changes in volume, net interest spread and net interest margin. Volume relates to the
level of interest-earning assets and interest-bearing liabilities. Net interest spread
refers to the difference between the yield on interest-earning assets and the rate paid on
interest-bearing liabilities. Net interest margin refers to net interest income divided by
total interest-earning assets and is influenced by the level and mix of interest-earning
assets and interest-bearing liabilities. Net interest income before provision for loan
losses totaled $31.2 million for the three months ended March 31, 2007, an increase of
$2.1 million, or 7.1%, compared to $29.1 million for the three months ended March 31,
2006. The increase in net interest income was primarily attributable to an increase in the
average balance of interest-earning assets.

Our
average interest rate spread for the three months ended March 31, 2007 and 2006 was 3.50%
and 3.57%, respectively. The decrease in our average interest rate spread was attributable
to the increase in the average rate paid on interest-bearing liabilities being greater
than the increase in the yield earned on our interest-earning assets, primarily our net
loan portfolio. The average yield on interest-earning assets was 7.38% for the three
months ended March 31, 2007, a 71 basis point increase compared to 6.67% for the three
months ended March 31, 2006. The increase in the average yield earned on interest-earning
assets was primarily related to an increase in the average yield earned on loans
receivable. Our average yield earned on loans receivable for the three months ended March
31, 2007 and 2006 was 7.52% and 6.82%, respectively. This increase was primarily the
result of our lending strategy to focus on loans with relatively higher yields, adjustable
interest rates and/or shorter terms to maturity. Our average rate paid on interest bearing
liabilities was 3.88% for the three months ended March 31, 2007, an increase of 78 basis
points compared to 3.10% for the three months ended March 31, 2006. The increase in the
average rate paid on interest-bearing liabilities was primarily the result of customers
migrating to higher-yielding deposit products such as time deposits and money market
accounts coupled with increased borrowing cost associated with FHLBank advances.

---

Our
net interest margin (net interest income (annualized) divided by average interest-earning
assets) increased to 3.93% for the three months ended March 31, 2007 compared to 3.87% for
the three months ended March 31, 2006. The increase in our net interest margin for the
three months ended March 31, 2007 was primarily the result of increases in the average
balance of and average yield earned on loans receivable. The average balance of our total
interest-earning assets was $3.2 billion for the three months ended March 31, 2007, an
increase of $167.5 million, or 5.6%, compared to $3.0 billion for the three months ended
March 31, 2006. We anticipate that average interest rate spread and net interest margin
compression may occur throughout 2007 due to increased deposit interest costs and
refinancing of our FHLBank advances and other borrowings.

Rate/Volume Analysis. The following table shows the extent to which changes
in interest rates and changes in the volume of interest-related assets and liabilities
affected our interest income and expense during the periods indicated. For each category
of interest-earning assets and interest-bearing liabilities, information is provided on
changes attributable to: (1) changes in rate (change in rate multiplied by prior year
volume), and (2) changes in volume (change in volume multiplied by prior year rate). The
combined effect of changes in both rate and volume has been allocated proportionately to
the change due to rate and the change due to volume.

Interest
Income.Our total interest income for the three months ended March 31, 2007 was
$58.7 million, an increase of $8.5 million, or 16.9%, compared to $50.2 million for the
three months ended March 31, 2006. Interest income on loans receivable totaled $56.1
million for the three months ended March 31, 2007, an increase of $8.0 million, or 16.6%,
compared to $48.1 million for the three months ended March 31, 2006. The average balance
of loans receivable increased $157.1 million, or 5.6%, to $3.0 billion for the three
months ended March 31, 2007 compared to $2.8 billion for the three months ended March 31,
2006. The average yield earned on loans receivable increased to 7.52% for the three months
ended March 31, 2007 compared to 6.82% for the three months ended March 31, 2006.

The
increase in total interest income for the three months ended March 31, 2007 was primarily
attributable to an increase in interest income on loans receivable. The increase in
interest income on loans receivable was primarily attributable to an increase in the
average balance of loans receivable and to a lesser extent an increase in the average
yield earned on loans receivable. The increase in the average balance and average yield
earned on loans receivable was primarily the result of our lending strategy to focus on
and sustain our holdings of loans with relatively higher yields, adjustable interest rates
and/or shorter terms to maturity.

Interest
Expense.Our total interest expense for the three months ended March 31, 2007 was
$27.5 million, an increase of $6.4 million, or 30.5%, compared to $21.1 million for the
three months ended March 31, 2006. Interest expense on deposits totaled $17.9 million for
the three months ended March 31, 2007, an increase of $4.8 million, or 36.2%, compared to
$13.1 million for the three months ended March 31, 2006. Interest expense on FHLBank
advances and other borrowings increased $1.7 million, or 21.0%, to $9.6 million for the
three months ended March 31, 2007 compared to $7.9 million for the three months ended
March 31, 2006. The average rate paid on interest-bearing deposits was 3.69% and 2.78% for
the three months ended March 31, 2007 and 2006, respectively. The average rate paid on
FHLBank advances and other borrowings increased to 4.29% for the three months ended March
31, 2007 compared to 3.83% for the three months ended March 31, 2006. Additionally, the
average balance of our interest-bearing liabilities totaled $2.8 billion for the three
months ended March 31, 2007, an increase of $114.1 million, or 4.2%, compared to $2.7
billion for the three months ended March 31, 2006. The average balance of our
interest-bearing deposits increased $47.6 million, or 2.5%, to $1.9 billion for the three
months ended March 31, 2007 compared to the three months ended March 31, 2006. The average
balance of our FHLBank advances and other borrowings totaled $892.1 million for the three
months ended March 31, 2007, an increase of $66.5 million, or 8.1%, compared to $825.6
million for the three months ended March 31, 2006.

The
increase in interest expense was attributable to an increase in the average rate paid on
interest-bearing liabilities. This increase was primarily the result of the increase in
the average rate paid on time deposits and money market accounts which is a result of
customers migrating to higher-yielding deposit products.

Provision
for Loan Losses. We establish provisions for loan losses in order to
maintain the allowance for loan losses at a level we believe, to the best of our
knowledge, covers all known and inherent losses in the portfolio that are both probable
and reasonable to estimate at each reporting date. Management performs reviews no less
frequently than quarterly in order to identify these inherent losses and to assess the
overall collection probability for the loan portfolio. Our reviews consist of a
quantitative analysis by loan category, using historical loss experience, and
consideration of a series of qualitative loss factors (See Note 2 to the Consolidated
Financial Statements, Critical Accounting Policies  Allowance for Loan
Losses).

We
recorded a provision for loan losses of $1.5 million for the three months ended March 31,
2007 compared to $1.3 million for the three months ended March 31, 2006, an increase of
$137,000, or 10.3%. At March 31, 2007 our nonperforming loans totaled $40.3 million, or
1.32% of net loans, compared to $30.1 million, or 0.99% of net loans, at December 31,
2006. The increase in nonperforming loans at March 31, 2007 related primarily to an $11.8
million increase in nonperforming residential construction loans. Our focus on loans with
relatively higher yields, adjustable interest rates and/or shorter terms to maturity also
subjects us to a potentially higher degree of credit risk. Our loan delinquency rate (30
or more days delinquent) at March 31, 2007 as a percentage of net loans (before allowance
for loan losses) was 2.59% compared to 1.89% at December 31, 2006. We anticipate that the
level of loan delinquencies may continue to increase for the foreseeable future.

During
the three months ended March 31, 2007 and 2006, we charged-off, net of recoveries,
$691,000 and $422,000, respectively. Charge-offs, net of recoveries, during the three
months ended March 31, 2007 consisted primarily of $399,000 of consumer loans, $172,000 of
residential construction loans, $90,000 of land and land development loans and $90,000 of
business loans. Our charge-offs, net of recoveries, as a percentage of average loans
outstanding were 0.09% and 0.06% at March 31, 2007 and 2006, respectively. Our strategy of
focusing on loans with relatively higher yields, adjustable interest rates and/or shorter
terms to maturity subjects us to an increased level of credit risk which has resulted in
an increased amount of loan delinquencies and charge-offs.

Noninterest
Income.Noninterest income for the three months ended March 31, 2007 was $7.0
million, an increase of $598,000, or 9.3%, compared to $6.4 million for the three months
ended March 31, 2006.

Growth
in noninterest income during the three months ended March 31, 2007 compared to the three
months ended March 31, 2006 was primarily attributable to the increase in deposit account
and debit card fees. The increase in deposit account and debit card fees was largely due
to an increase in the number of transaction accounts and volume of activity.

The
increase in noninterest expense during the three months ended March 31, 2007 compared to
the three months ended March 31, 2006 was primarily attributable to increases in employee
compensation, employee benefits and payroll taxes. The increase in employee compensation,
employee benefits and payroll taxes resulted from personnel growth and annual salary
increases. At March 31, 2007 and 2006, we had 856 and 792 full-time equivalent employees,
respectively. We had 850 full-time equivalent employees at December 31, 2006.

Income
Tax Expense.Our income tax expense increased by $191,000, or 3.4%, to $5.9
million for the three months ended March 31, 2007 compared to $5.7 million for the three
months ended March 31, 2006. The increase in income tax expense for the three months ended
March 31, 2007 compared to the same period in 2006 was primarily due to an increase in net
income. The effective income tax rate for the three months ended March 31, 2007 was 38.4%
compared to 38.1% for the three months ended March 31, 2006.

# Liquidity

Our
primary sources of funds are deposits; amortization of loans; loan prepayments and
maturity of loans; maturity or sale of investment and mortgage-backed securities; and
other funds provided from operations. While scheduled payments from the amortization of
loans and mortgage-backed securities and maturing investment securities are relatively
predictable sources of funds, deposit flows and loan prepayments can be greatly influenced
by general interest rates, economic conditions and competition. We utilize FHLBank
advances and other borrowings and brokered time deposits as additional funding sources.

We
actively manage our liquidity in an effort to maintain an adequate liquidity margin over
the level necessary to support expected and potential loan fundings and deposit
withdrawals. Our liquidity level may vary throughout the year, depending on economic
conditions, deposit fluctuations and loan funding needs.

During
the three months ended March 31, 2007, net cash provided by operating activities was $15.1
million, which consisted primarily of net income. Net cash used in investing activities
during the three months ended March 31, 2007 was $15.1 million and primarily related to
the purchase of available for sale investment securities partially offset by cash inflows
from matured investment securities. Net cash used in financing activities was $2.7 million
for the three months ended March 31, 2007 and consisted primarily of cash outflows related
to the repayment of FHLBank advances (including line of credit) and cash dividends paid on
our common stock partially offset by cash inflows from deposits.

Deposits,
particularly core deposits, provide a more preferable source of funding than FHLBank
advances and other borrowings. However, to the extent that competitive or market factors
do not allow us to meet our funding needs with deposits alone, FHLBank advances and other
borrowings provide a readily available alternative source of liquidity. Deposits increased
$98.4 million, or 4.8%, to $2.2 billion at March 31, 2007 compared to $2.1 billion at
December 31, 2006. The increase in deposits during the three months ended March 31, 2007
was used to reduce our FHLBank advances. At March 31, 2007, we had time deposits maturing
within the next 12 months amounting to $1.1 billion. Based upon historical experience, we
anticipate that a significant portion of the maturing time deposits will be renewed with
us.

In
addition to cash flows generated by loan and securities payments and prepayments, we have
additional borrowing capacity to fund our asset growth. The average balance of our FHLBank
advances and other borrowings was $892.1 million for the three months ended March 31, 2007
compared to $825.6 million for the three months ended March 31, 2006. To date,
substantially all of our borrowings have consisted of FHLBank advances. Pursuant to
blanket collateral agreements with the FHLBank, we have pledged qualifying residential,
multi-family residential and commercial real estate mortgages, residential construction,
commercial construction and agricultural real estate loans as collateral for our FHLBank
advances.

# Aggregate Contractual
Obligations and Off-Balance Sheet Arrangements

We
have sufficient liquidity to fund existing and future loan commitments, to fund maturing
time deposits and demand deposit withdrawals, to invest in other interest-earning assets
and to meet operating expenses. At March 31, 2007, we had the following contractual
obligations (excluding bank deposits and interest) and lending commitments:

We
have not used, and have no intention to use, any significant off-balance sheet financing
arrangements for liquidity purposes or otherwise. Our primary financial instruments with
off-balance sheet risk are limited to loan servicing for others, our obligations to fund
loans to customers pursuant to existing commitments and commitments to purchase and sell
mortgage loans. In addition, we have certain risks due to limited recourse arrangements on
loans serviced for others and recourse obligations related to loan sales. At March 31,
2007, the maximum total dollar amount of such recourse was approximately $17.8 million.
Based on historical experience, at March 31, 2007, we had established a liability of
$738,000 with respect to this recourse obligation. In addition, we have not had, and have
no intention to have, any significant transactions, arrangements or other relationships
with any unconsolidated, special purpose entities.

# Regulatory Capital

We
are subject to various regulatory capital requirements administered by federal banking
agencies. Failure to meet minimum capital requirements can initiate certain mandatory and
additional discretionary actions by regulators that, if undertaken, could have a direct
material adverse effect on our financial condition and results of operations. Under
capital adequacy guidelines and the regulatory framework for prompt corrective action, we
must meet specific capital guidelines that involve quantitative measures of our assets,
liabilities and certain off-balance sheet items as calculated under regulatory accounting
practices. The capital amounts and classifications are also subject to qualitative
judgments by the regulators about components, risk weightings and other factors.

Quantitative
measures that have been established by regulation to ensure capital adequacy require that
we maintain minimum capital amounts and ratios (set forth in the following table). Our
primary regulatory agency, the Office of Thrift Supervision (OTS), requires
that we maintain minimum ratios of tangible capital (as defined in the regulations) of
1.5%, core capital (as defined) of 4.0% and total risk-based capital (as defined) of 8.0%.
As of March 31, 2007, we exceed all capital requirements to which we are subject.

As
of March 31, 2007 and December 31, 2006, the most recent notifications from the OTS
categorized the Bank as well capitalized under the regulatory framework. There are no
conditions or events since these notifications that we
believe have changed the Banks category. The actual capital amounts and ratios as of
March 31, 2007 and December 31, 2006 are presented in the following table:
