Part II:   OTHER INFORMATION



Item 1A.   Risk Factors



An investment in PNBCs common stock is subject to risks inherent to the Corporations business. An investor should carefully consider the risks described below and information contained in this Form 10-Q together before deciding to purchase PNBC common stock. The risks and uncertainties described below are not the only ones facing the Corporation. Additional risks and uncertainties that management is not aware of or focused on or deems immaterial may arise or become material in the future and affect PNBCs business. If any of these risks actually occur, PNBCs financial condition and results of operations could be materially and adversely affected. If this were to happen, the value of PNBC common stock could decrease significantly.



PNBCs concentration of agricultural loans is subject to risks that could adversely affect earnings.



PNBCs agricultural and agricultural real estate loan portfolio total $134.4 million at June 30, 2006, comprising 23.2% of total loans. The primary risks associated with agricultural loans are weather and borrowers management. In the event of catastrophic weather conditions, such as severe drought or flooding, these loans would represent a higher risk due to poor crop sales and reduced cash flow that could impact the borrowers ability to repay the loan on a timely basis.



Changes in interest rates could adversely impact the financial condition and results of operations.



PNBCs ability to make a profit, like that of most financial institutions, substantially depends upon its net interest income. However, certain assets and liabilities may react differently to changes in market interest rates. In a period of changing rates, interest expense may increase at different rates than the interest earned. Accordingly, changes in interest rates could decrease net interest income.

---

The allowance for loan losses may not be sufficient to cover actual loan losses decreasing earnings.



In determining the appropriate level of allowance for loan losses, management considers, among other things, the overall composition of the loan portfolio, types of loans, past loss experience, loan delinquencies, potential substandard and doubtful loans, underlying collateral, and other factors that, in managements best judgment, deserve evaluation. Although management monitors the allowance monthly and considers it adequate to absorb probable losses at June 30, 2006, if any of the assumptions are incorrect, the allowance may not be sufficient to cover future loan losses. Future adjustments may be necessary to allow for different economic conditions or adverse developments in the loan portfolio. Consequently, a problem with one or more loans could require the Corporation to significantly increase the level of its provision for loan losses resulting in a reduction of earnings.



The Internal Controls of PNBC may not be effective.



Management reviews and tests on a quarterly basis its system of internal controls, disclosure controls and procedures, and corporate governance polices and procedures. Any system of internal controls, however well designed, is based on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are actually being met. Any failure or circumvention of these controls could have a material adverse affect on the Corporations financial condition and results of operations.



There is competition within the PNBC market areas which may limit growth and profitability.



Because the banking business is highly competitive, PNBC faces significant competition both in originating loans and attracting deposits. Competition can not only be effected by the pricing of loans and deposits, but also by the variety of products offered. The ability of the Corporation to continue to grow in the markets served while effectively managing interest rate risk is contingent upon being able to operate in this competitive environment, which ultimately affects the Corporations profitability.



The success of PNBC is dependent on hiring and retaining key personnel.



PNBCs performance is largely dependent on the talents and efforts of highly skilled individuals. The Corporation relies on key personnel to manage and operate its business and the loss of any of these individuals may adversely affect the Corporations ability to maintain and/or manage the business effectively. This could have a material adverse affect on the Corporations financial condition and results of operations.



PNBC operates in a highly regulated environment.



PNBC is subject to extensive regulation, supervision and examination. Any changes in the regulations or applicable laws and the failure of the Corporation to comply with any of the regulations and laws could have a material adverse effect on the Corporations financial condition and results of operations.

PRINCETON NATIONAL BANCORP, INC. AND SUBSIDIARY
Notes to Consolidated Financial Statements
(Unaudited)

The accompanying unaudited
condensed consolidated financial statements reflect all adjustments, which, in the opinion of management, are necessary for a fair
presentation of the results of the interim periods ended June 30, 2006 and 2005, and all such adjustments are of a normal
recurring nature. The 2005 year-end consolidated balance sheet data was derived from audited financial statements, but do not
include all disclosures required by generally accepted accounting principles.

The unaudited consolidated
financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information
required by accounting principles generally accepted in the United States of America for complete financial statements and related
footnote disclosures. In the opinion of management, all adjustments (consisting only of normal recurring accruals) considered for
a fair presentation of the results for the interim period have been included. For further information, refer to the consolidated
financial statements and notes included in the Registrants 2005 Annual Report on Form 10-K. Results of operations for
interim periods are not necessarily indicative of the results that may be expected for the year. Certain amounts in the 2005
consolidated financial statements have been reclassified to conform to the 2006 presentation.

# (2)   GOODWILL AND INTANGIBLE ASSETS

The balance of goodwill, net
of accumulated amortization, totaled $22,678,000 at June 30, 2006 and $22,665,000 at December 31, 2005. The balance of intangible
assets, net of accumulated amortization, totaled $6,382,000 and $6,843,000 at June 30, 2006 and December 31, 2005, respectively.

The following table
summarizes the Corporations intangible assets, which are subject to amortization, as of June 30, 2006 and December 31, 2005.

|                        |      |  |     

Amortization expense of the
intangible assets in the table above totaled $461,000 for the six months ended June 30, 2006 and $104,000 for the six months ended
June 30, 2005, respectively, with the increase related to the amortization of the core deposit intangible of $357,000, resulting
from the acquisition of Somonauk FSB Bancorp, Inc. in August, 2005. The amortization expense of these intangible assets will be
approximately $460,000 for the remainder of 2006.

The Corporation has
originated mortgage servicing rights which are included in other assets on the consolidated balance sheets. Mortgage servicing
rights are amortized in proportion to, and over the period of, estimated net servicing income on a basis similar to the interest
method using an accelerated amortization method and are subject to periodic impairment testing. As of June 30, 2006, no impairment
had been recorded during the year. Changes in the carrying value of capitalized mortgage servicing rights are summarized as
follows:

The Corporation services
loans for others with unpaid principal balances at June 30, 2006 and December 31, 2005 of approximately $230,156,000, and
$202,042,000, respectively.

The following table shows the
future estimated amortization expense for mortgage servicing rights based on existing balances as of June 30, 2006. The
Corporations actual amortization expense in any given period may be significantly different from the estimated amounts
displayed depending on the amount of additional servicing rights, changes in mortgage interest rates, actual prepayment speeds,
and market conditions.

# (3)   STOCK BASED COMPENSATION

Effective January 1, 2006,
the Company adopted Financial Accounting Standards Board Statement No. 123R (FASB 123R) requiring the recording of
future compensation expense based on grant date fair value with regard to stock options as opposed to recording compensation
expense equal to the intrinsic value of stock options on grant date which generally resulted in no compensation expense being
recorded. On December 20, 2005, the Company announced that the Personnel Policy and Salary Committee of the Board of Directors
approved the accelerated vesting of all outstanding unvested stock options to purchase shares of common stock of PNBC granted
through the Companys non-qualified stock option plan. The unvested options related to awards granted in 2003 and 2004 to
directors and officers of the Company. All of the unvested options were in the money, in a range from $4.42 to $22.06 per share,
at the date vesting was accelerated. There was no compensation cost recognized in the financial statements from the vesting
decision. By accelerating the vesting of these options, the Company estimates approximately $925,000 of future compensation
expense will be eliminated, which the Company believes is in the best interests of the shareholders. Options to purchase 142,133
shares of PNBC common stock, which otherwise would have vested from time to time over the next two years, became immediately
exercisable as a result of this decision. The remaining terms for each of the options granted remain the same. This acceleration
became effective as of December 31, 2005. Additionally, the Company announced the stock option award for 2005 of 80,700 shares was
granted with full vesting. This decision was made to eliminate additional future compensation expense of approximately $163,000
for each of the next three years, beginning in 2006.

The number of shares of
common stock authorized under the stock option plans is 502,500. The option exercise price must be at least 100% of the fair
market value of the common stock on the date of grant, and the option term cannot exceed ten years. A summary of the stock option
activity and related information follows:

# (4)   IMPACT OF NEW ACCOUNTING STANDARDS

In June 2005, the Financial
Accounting Standards Board (FASB) issued SFAS No. 154 (FAS 154), Accounting Changes and Error Corrections 
a replacement of APB Opinion No. 20 and FASB Statement No. 3 (FAS 154). FAS 154 changes the requirements for the accounting
for and reporting of a change in accounting principle and also applies to all voluntary changes in accounting principle. FAS 154
is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The adoption
of this statement did not have a material effect on the Corporations consolidated financial statements.

14

---

In February 2006, the FASB
issued SFAS No. 155 (FAS 155), Accounting for Certain Hybrid Financial Instruments: an amendment of FASB Statements
No. 133 and 140. FAS 155 permits fair value re-measurement for any hybrid financial instrument that contains an
embedded derivative that otherwise would require bifurcation, clarifies which interest-only strips and principal-only strips are
not subject to the requirements of Statement 133, establishes a requirement to evaluate interests in securitized financial assets
to identify interests that are freestanding derivatives or that are hybrid financial instruments that contain an embedded
derivative requiring bifurcation, clarifies that concentrations of credit risk in the form of subordination are not embedded
derivatives, and amends Statement 140 to eliminate the prohibition on a qualifying special purpose entity from holding a
derivative financial instrument that pertains to a beneficial interest other than another derivative financial instrument. FAS 155
is effective for all financial instruments acquired or issued after the beginning of an entitys first fiscal year that
begins after September 15, 2006. The Corporation does not expect the adoption of FAS 155 will have a material
impact on its results of operations, financial position or liquidity.

In March 2006, the FASB
issued SFAS No. 156 (FAS 156), Accounting for Servicing of Financial Assets  an amendment of FAS 140, Accounting
for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities, with respect to the accounting for separately
recognized servicing assets and liabilities. FAS 156 requires an entity to recognize a servicing asset or servicing liability each
time it undertakes an obligation to service a financial asset by entering into a servicing contract in any of the following
situations: a transfer of the servicers financial assets that meets the requirements for sale accounting, a transfer of the
servicers financial assets to a qualifying special-purpose entity in a guaranteed mortgage securitization in which the
transferor retains all of the resulting securities and classifies them as either available-for-sale securities or trading
securities in accordance with FAS 115, Accounting for Certain Investments in Debt and Equity Securities, or an
acquisition or assumption of an obligation to service a financial asset that does not relate to financial assets of the servicer
or its consolidated affiliates. FAS 156 maintains the requirement set forth under FAS 140 that all separately recognized servicing
assets and servicing liabilities are to be initially measured at fair value, if practicable. In regard to subsequent measurement
methods for each class of separately recognized servicing assets and servicing liabilities, FAS 156 amends FAS 140 to allow for
either an amortization method or a fair value measurement method. FAS 156 is effective as of the beginning of the fiscal year that
begins after September 15, 2006. The Corporation does not expect the adoption of FAS 156 will have a material impact on its results of
operations, financial position, or liquidity.

In July 2006, the FASB
issued FASB Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes  an Interpretation of FASB
Statement 109, which provides guidance on the measurement, recognition, and disclosure of tax positions taken or expected to
be taken in a tax return. The Interpretation also provides guidance on derecognition, classification, interest and penalties, and
disclosure. FIN 48 prescribes that a tax position should only be recognized if it is more-likely-than-not that the position will
be sustained upon examination by the appropriate taxing authority. A tax position that meets this threshold is measured as the
largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. The cumulative effect
of applying the provisions of FIN 48 is to be reported as an adjustment to the beginning balance of retained earnings in the
period of adoption. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company is currently
assessing the impact, if any, that the adoption of this Interpretation will have on its financial statements.

Schedule 6



PRINCETON NATIONAL BANCORP, INC. AND SUBSIDIARY

MANAGEMENTS DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

For the three and six months ended June 30, 2006 and 2005



The following discussion provides information about Princeton National Bancorp, Inc.s (PNBC or the Corporation) financial condition and results of operations for the three and six month periods ended June 30, 2006 and 2005. This discussion should be read in conjunction with the attached consolidated financial statements and notes thereto. Certain statements in this report constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including, but not limited to those statements that include the words believes, expects, anticipates, estimates, or similar expressions. PNBC cautions that such forward-looking statements involve risks and uncertainties that may cause actual results to differ materially from
those expressed or implied. Such risks and uncertainties include potential change in interest rates, competitive factors in the financial services industry, general economic conditions, the effect of new legislation, and other risks detailed in documents filed by the Corporation with the Securities and Exchange Commission from time to time.



RESULTS OF OPERATIONS



Net income for the second quarter of 2006 was $1,581,000, or basic earnings per share of $0.47 (diluted earnings per share of $0.46), as compared to net income of $1,693,000 in the second quarter of 2005, or basic earnings per share of $0.56 (diluted earnings per share of $0.55). This represents a decrease of $112,000 (6.6%) or $.09 per basic and diluted share. The lower net income figure is primarily attributed to a decrease in the net yield on interest-earning assets from 3.88% for the second quarter of 2005 to 3.43% for the second quarter of 2006. Also contributing to the lower net income were additional expenses incurred with the opening of our newest office in Aurora, Illinois on May 1, 2006. Net income for the first six months of 2006 was $3,231,000, or basic earnings per share of $0.96 (diluted earnings per share of $0.95), compared to net income of $3,401,000, or basic earnings
per share of $1.12 (diluted earnings per share of $1.11) for the first six months of 2005. This represents a decrease of $170,000 (5.0%) or $0.16 per basic and diluted share. The lower net income figure is again primarily attributed to a decrease in the net yield on interest-earning assets from 3.90% for the first six months of 2005 to 3.47% for the first six months of 2006.   The annualized return on average assets and return on average equity were 0.68% and 9.94%, respectively, for the second quarter of 2006, compared with 1.01% and 13.02% for the second quarter of 2005. For the six-month periods, the annualized return on average assets and return on average equity were 0.70% and 10.24%, respectively for 2006, compared with 1.04% and 13.13%, respectively for 2005.



Net interest income before provision for loan losses was $6,454,000 for the second quarter of 2006, compared to $5,495,000 for the second quarter of 2005 (an increase of $959,000 or 17.5%). This increase is a result of an increase in average interest-earning assets of $214.7 million over the past twelve months, after the acquisition of Somonauk FSB Bancorp, Inc. (FSB) on August 1, 2005. For the three months ended June 30, 2006, average interest-earning assets were $826.6 million compared to $611.9 million for the three months ended June 30, 2005. However, the resulting net yield on interest-earning assets (on a fully taxable equivalent basis) decreased to 3.43% in the second quarter of 2006 from 3.88% in the second quarter of 2005, further contributing to the lower net income reported above. Net
interest income before any provision for loan losses was $12,983,000 for the first six months of 2006, compared to $10,870,000 for the first six months of 2005 (an increase of $2.1 million or 19.4%). The resulting net yield on interest-earning assets (on a fully taxable equivalent basis) decreased to 3.47% in the first half of 2006 from 3.90% in the first half of 2005. As interest rates have risen quickly over the past year, the yield on interest-earning assets (increased 66 basis points) has not been able to keep pace with the rising cost of interest-bearing liabilities (increased 109 basis points). A further increase to the cost of interest-bearing liabilities has occurred because average time deposits now account for 48.5% of average interest-bearing liabilities for the six months ended June 30, 2006 compared to 46.6% for the same period in 2005. The average cost of the CD portfolio has risen 138 basis points in the past twelve months.

The Corporations provision for loan loss expense recorded each quarter is determined by managements evaluation of the risk characteristics of the loan portfolio. For the second quarter of 2006, PNBC had net charge-offs of $103,000, compared to net charge-offs of $11,000 for the second quarter of 2005. For the six-month comparable periods, PNBC had net charge-offs of $212,000 in 2006 and net charge-offs of $22,000 in 2005. PNBC recorded a loan loss provision of $85,000 in the second quarter of 2006 and $95,000 in the first half of 2006 compared to a provision of $0 in the first six months of 2005. The ratio of non-performing loans to total loans at June 30, 2006 remains very low at 0.76% compared to 0.47% at June 30, 2005.



Non-interest income totaled $2,640,000 for the second quarter of 2006, compared to $2,037,000 in the second quarter of 2005, an increase of $603,000 (or 29.6%). Service charges on deposits and other service charges had the largest increases of $332,000 and $111,000, respectively, due to a larger customer base following the acquisition of Somonauk FSB Bancorp in the third quarter of 2005. Annualized non-interest income as a percentage of average total assets decreased to 1.14% for the second quarter of 2006 from 1.22% for the same period in 2005. Year-to-date in 2006, non-interest income totaled $5,148,000 compared to $3,912,000 for the first half of 2005, an increase of $1,236,000 (or 31.6%). Again, the primary reason for the positive change is the increase in service charges on deposits and other service charges (increasing $621,000 and $240,000, respectively). The Corporation recorded
gains from the sales of securities available-for-sale of $60,000 in the first six months of 2006 compared to $28,000 for the first six months of 2005. The Corporation also recorded a pre-tax gain of $90,000 in conjunction with the sale of $16,500,000 of first mortgage loans during the first quarter of 2006. These funds will be used to meet the Corporations short-term liquidity needs and fund future loans at higher interest rates, thus improving the net interest margin. The servicing of these loans was retained which will help further increase non-interest income. Additionally, during the second quarter of 2006, the subsidiary bank completed the sale of the farm management department generating a pre-tax gain of $77,000. Annualized non-interest income as a percentage of total average assets decreased from 1.19% for the first six months of 2005, to 1.11% for the same period in 2006.



Total non-interest expense for the second quarter of 2006 was $7,146,000, an increase of $1,847,000 (or 34.9%) from $5,299,000 in the second quarter of 2005. All categories of non-interest expense were higher due to the increased number of employees and facilities resulting from the FSB acquisition and the opening of new locations in Plano during the 4th quarter of 2005 and Aurora during the 2nd quarter of 2006. Annualized non-interest expense as a percentage of total average assets decreased to 3.08% for the second quarter of 2006, compared to 3.21% for the same period in 2005. Year-to-date non-interest expense for the first half of 2006 was $14,237,000, an increase of $3,941,000 (or 38.3%) from the $10,296,000 for the first half of 2005 for the same reasons mentioned above in comparing the second quarter activity. Annualized non-interest expense as a percentage of
total average assets also decreased to 3.08% for the first six months of 2006, compared to 3.14% for the same period in 2005.

INCOME TAXES



Income tax expense totaled $282,000 for the second quarter of 2006, as compared to $540,000 for the second quarter of 2005. The effective tax rate was 15.1% for the three month period ended June 30, 2006 and 24.2% for the three month period ended June 30, 2005. Income tax expense totaled $568,000 for the first six months of 2006, as compared to $1,085,000 for the first six months of 2005. The effective tax rate was 15.0% for the six month period ended June 30, 2006 and 24.2% for the six month period ended June 30, 2005.    The lower effective tax rate in 2006 (both quarter and year-to-date) is due to a significant increase in the amount of tax-exempt investment securities in the Corporations investment portfolio, as well as lower pre-tax income.



ANALYSIS OF FINANCIAL CONDITION



Total assets at June 30, 2006 decreased to $942,527,000 from $945,263,000 at December 31, 2005 (a decrease of $2.7 million or 0.3%). Investment balances totaled $247,533,000 at June 30, 2006, compared to $251,486,000 at December 31, 2005 (a decrease of $4.0 million or 1.6%). The decrease in the investment portfolio was a result of managements decision to partially fund new loans with maturing investments rather than be overly competitive with the rising price of deposits. Total deposits increased slightly to $802,327,000 at June 30, 2006 from $798,558,000 at December 31, 2005 (an increase of $3.8 million or 0.5%). Comparing categories of deposits at June 30, 2006 to December 31, 2005, time deposits increased by $11.0 million (or 3.0%) and savings deposits increased $8.7 million (or 8.0%). Conversely, interest-bearing demand deposits decreased $11.0 million (or 4.9%) and demand
deposits decreased $4.9 million (or 4.8%). Borrowings, consisting of customer repurchase agreements, notes payable, treasury, tax, and loan (TT&L) deposits, federal funds purchased, and Federal Home Loan Bank advances, decreased from $72,575,000 at December 31, 2005 to $67,284,000 at June 30, 2006 (a decrease of $5.3 million or 7.3%).



Loan balances, net of unearned interest, decreased to $578,336,000 at June 30, 2006, compared to $581,724,000 at December 31, 2005 (a decrease of $3.4 million or 0.6%). This decease was the result of the aforementioned loan sale of $16.5 million of residential real estate mortgages during the first quarter of 2006. Non-performing loans increased to $4,389,000 or 0.76% of net loans at June 30, 2006, as compared to $3,824,000 or 0.66% of net loans at December 31, 2005. Although non-performing loans have increased, all are individually evaluated and management continues to maintain adequate reserves in the allowance for loan losses.



ASSET QUALITY



For the six months ended June 30, 2006, the subsidiary bank charged off $398,000 of loans and had recoveries of $186,000, compared to charge-offs of $124,000 and recoveries of $102,000 during the six months ended June 30, 2005. The allowance for loan losses is based on factors that include the overall composition of the loan portfolio, types of loans, underlying collateral, past loss experience, loan delinquencies, substandard and doubtful credits, and such other factors that, in managements reasonable judgment, warrant consideration. The adequacy of the allowance is monitored monthly. At June 30, 2006, the allowance was $3,080,000 which is 70.2% of non-performing loans and 0.53% of total loans, compared with $3,109,000 which was 81.3% of non-performing loans and 0.53% of total loans at December 31, 2005.

At June 30, 2006, non-accrual loans were $4,377,000 compared to $3,822,000 at December 31, 2005. Impaired loans totaled $2,609,000 at June 30, 2006 compared to $2,204,000 at December 31, 2005. The total amount of loans ninety days or more past due and still accruing interest at June 30, 2006 was $12,000 compared to $0 at December 31, 2005. There was a specific loan loss reserve of $390,000 established for impaired loans as of June 30, 2006 compared to a specific loan loss reserve of $111,000 at December 31, 2005. PNBCs management analyzes the allowance for loan losses monthly and, again, believes the current level of allowance is adequate to meet probable losses as of June 30, 2006.



CAPITAL RESOURCES



Federal regulations require all financial institutions to evaluate capital adequacy by the risk-based capital method, which makes capital requirements more sensitive to the differences in the level of risk assets. At June 30, 2006, total risk-based capital of PNBC was 9.93%, compared to 9.76% at December 31, 2005. The Tier 1 capital ratio decreased from 7.83% at December 31, 2005, to 6.82% at June 30, 2006. Total stockholders equity to total assets at June 30, 2006 increased to 6.76% from 6.68% at December 31, 2005.



LIQUIDITY



Liquidity is measured by a financial institutions ability to raise funds through deposits, borrowed funds, capital, or the sale of assets. Additional sources of liquidity include cash flow from the repayment of loans and the maturity of investment securities. Major uses of cash include the origination of loans and purchase of investment securities. Cash flows provided by operating and investing activities, offset by those used by financing activities, resulted in a net increase in cash and cash equivalents of $1,886,000 from December 31, 2005 to June 30, 2006. This increase was primarily due to a net increase in deposits, net decrease in investments and the proceeds from the sale of loans. For more detailed information, see PNBCs Consolidated Statements of Cash Flows.



FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK



The subsidiary bank is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The contract amounts of those instruments reflect the extent of involvement the subsidiary bank has in particular classes of financial instruments.



The subsidiary banks exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The subsidiary bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. At June 30, 2006, commitments to extend credit and standby letters of credit were approximately $134,376,000 and $8,973,000, respectively.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The subsidiary bank evaluates each customers creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary, by the subsidiary bank upon extension of credit is based on managements credit evaluation of the counter party. Collateral held varies, but may include real estate, accounts receivable, inventory, property, plant and equipment, and income-producing properties.



Standby letters of credit are conditional commitments issued by the subsidiary bank to guarantee the performance of a customer to a third party. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers. The subsidiary bank secures the standby letters of credit with the same collateral used to secure the loan.



LEGAL PROCEEDINGS



There are various claims pending against PNBCs subsidiary bank, arising in the normal course of business. Management believes, based upon consultation with legal counsel, that liabilities arising from these proceedings, if any, will not be material to PNBCs financial condition.



QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK



There has been no material change in market risk since December 31, 2005, as reported in PNBCs 2005 Annual Report on Form 10-K.



EFFECTS OF INFLATION



The consolidated financial statements and related consolidated financial data presented herein have been prepared in accordance with accounting principles generally accepted in the United States of America and practices within the banking industry which require the measurement of financial condition and operating results in terms of historical dollars, without considering the changes in the relative purchasing power of money over time due to inflation. Unlike most industrial companies, virtually all the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates have a more significant impact on a financial institutions performance than the effects of general levels of inflation.

|(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.

Based on this evaluation, Messrs. Sorcic and Fanning concluded that, as of the date of their evaluation, our disclosure controls were effective.
