Notes to the Condensed Consolidated Financial Statements

(Unaudited)

March 31, 2006

Note 1: General Summary of Significant Accounting Policies
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. The results of operations reflect interim adjustments, all of which are of a normal recurring nature and which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. The interim results for the three month periods ended March 31, 2006 and 2005 are not necessarily indicative of the results expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes as well as other information included in the Company's Annual Report on Form 10-K for the year ended December 31, 2005.

Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, The Vintage Bank (the "Bank"). All significant intercompany accounts and transactions have been eliminated in consolidation.

Nature of Operations
The Bank operates 10 branch offices in the California counties of Napa and Solano.  The Bank offers a full range of commercial banking services to individuals and the business and agricultural communities in Napa and Solano Counties.  The Bank emphasizes retail commercial banking operations and accepts checking and savings deposits, makes consumer, commercial, construction and real estate loans, and provides other customary banking services.  The Bank does not offer trust services and does not plan to do so in the near future.  There have been no material changes in services offered by the Bank.  The Bank makes annuities and mutual funds available to its customers through Linsco Private Ledger.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an on-going basis, the Company evaluates its estimates, including those related to the adequacy of the allowance for loan losses, investments, income taxes, contingencies and supplemental retirement plan liabilities. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results ma y differ from these estimates under different assumptions or conditions. The allowance for loan losses, income taxes and supplemental retirement plan liabilities are the only accounting estimates that materially affect the Company's consolidated financial statements.

Significant Group Concentration of Credit Risk

The Bank concentrates its lending activities in commercial, installment, construction and real estate loans made primarily to businesses and individuals located in Napa and Solano Counties.  The Company has a diversified loan portfolio within the business segments located in this geographical area.

Cash and Cash Equivalents
For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash on hand, amounts due from banks and federal funds sold.

Investment Securities
The Company classifies its debt and marketable equity securities into one of two categories:  available-for-sale or held-to-maturity.  Held-to-maturity securities are those securities which the Company has the ability and intent to hold until maturity. All other securities are classified as available-for-sale. During the three months ended March 31, 2006, and throughout 2005, the Company did not have any securities classified as held-to-maturity.

Available-for-sale securities are recorded at fair value. Unrealized gains and losses, net of the related tax effect, on available-for-sale securities are reported as a separate component of accumulated other comprehensive income (loss) in shareholders' equity until realized.

9

Premiums and discounts are amortized or accreted over the life of the related investment security as an adjustment to yield using the effective interest method. Dividend and interest income are recognized when earned. Realized gains and losses for securities are included in earnings and are derived using the specific identification method for determining the cost of securities sold. Unrealized losses due to fluctuations in fair value of securities held to maturity or available for sale are recognized through earnings when it is determined that an other than temporary decline in value has occurred.

Loans Held for Sale

Loans originated or purchased and considered held for sale are carried at the lower of cost or estimated market value in the aggregate.  Net unrealized losses are recognized through a valuation allowance by charges to income.

Loans
Loans are reported at the principal amount outstanding, net of unearned income and the allowance for loan losses. Loan origination and commitment fees and certain direct loan origination costs are deferred, and the net amount is amortized as an adjustment of the related loan's yield over the estimated life of the loan. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. Accrual of interest on loans is generally discontinued either when reasonable doubt exists as to the full, timely collection of interest or principal or when a loan becomes contractually past due by 90 days or more with respect to interest or principal. When loans are 90 days past due, but in Management's judgment are well secured and in the process of collection, they may be classified as accrual. When a loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed. Income on such loans is then recognized only to the extent that cash is received and where the f uture collection of principal is probable. Interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of Management, the loans are estimated to be fully collectible as to both principal and interest. All impaired loans are classified as nonaccrual loans.

Reserve for Unfunded Commitments
The reserve for unfunded commitments is established through a provision for losses - unfunded commitments charged to noninterest expense. The reserve for unfunded commitments is an amount that Management believes will be adequate to absorb probable losses inherent in existing commitments, including unused portions of revolving lines of credits and other loans, standby letters of credits, and unused deposit account overdraft privilege. The reserve for unfunded commitments is based on evaluations of the collectibility, and prior loss experience of unfunded commitments. The evaluations take into consideration such factors as changes in the nature and size of the loan portfolio, overall loan portfolio quality, loan concentrations, specific problem loans and related unfunded commitments, and current economic conditions that may affect the borrower's or depositor's ability to pay.

Allowance for Loan Losses

The allowance for loan losses is established through a provision for loan losses charged to expense. Loans and deposit related overdrafts are charged against the allowance for loan losses when Management believes that the collectibility of the principal is unlikely.  The allowance is an amount that Management believes will be adequate to absorb probable losses inherent in existing loans and leases, based on evaluations of the collectibility, impairment and prior loss experience of loans and leases. The evaluations take into consideration such factors as changes in the nature and size of the portfolio, overall portfolio quality, loan concentrations, specific problem loans, and current economic conditions that may affect the borrower's ability to pay. The Company defines a loan as impaired when it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impaired loans are measure d based on the present value of expected future cash flows discounted at the loan's original effective interest rate. As a practical expedient, impairment may be measured based on the loan's observable market price or the fair value of the collateral if the loan is collateral dependent. When the measure of the impaired loan is less than the recorded investment in the loan, the impairment is recorded through a valuation allowance.

Credit risk is inherent in the business of lending. As a result, the Company maintains an allowance for loan losses to absorb losses inherent in the Company's loan portfolio. This is maintained through periodic charges to earnings. These charges are shown in the Consolidated Income Statements as provision for loan losses. The balance of the Company's allowance for loan losses is meant to be an estimate of probable losses inherent in the portfolio. For purposes of this discussion, "loans" shall include all loans and lease contracts that are part of the Company's portfolio.

10

The Company formally assesses the adequacy of the allowance on a quarterly basis. Determination of the adequacy is based on ongoing assessments of the probable risk in the outstanding loan portfolio, and to a lesser extent the Company's loan commitments. These assessments include the periodic re-grading of credits based on changes in their individual credit characteristics including delinquency, seasoning, recent financial performance of the borrower, economic factors, changes in the interest rate environment, growth of the portfolio as a whole or by segment, and other factors as warranted. Loans are initially graded when originated. They are re-graded as they are renewed, when there is a new loan to the same borrower, when identified facts demonstrate heightened risk of nonpayment, or if they become delinquent. Re-grading of larger problem loans occur at least quarterly. Confirmation of the quality of the grading process is obtained by independent credit reviews conducted by consultants specifically hired for this purpose and by various bank regulatory agencies.

The Company's method for assessing the appropriateness of the allowance for loan losses and the reserve for unfunded commitments includes specific allowances for identified problem loans and leases as determined by SFAS 114, formula allowance factors for pools of credits, and allowances for changing environmental factors (e.g., interest rates, growth, economic conditions, etc.).

Based on the current conditions of the loan portfolio, Management believes that the allowance for loan losses, which stands at $5,020,000 at March 31, 2006, is adequate to absorb probable losses inherent in the Company's loan portfolio. No assurance can be given, however, that adverse economic conditions or other circumstances will not result in increased losses in the portfolio.

 The following tables summarize the activity in the allowance for loan losses for the periods indicated:

	For the three months ended
(in thousands)	March 31, 2006	March 31, 2005

Net Charge-offs	(4)	(4)
Balance at end of period	$5,020	$4,317
As a percentage of total loans:
Allowance for loan losses	1.16%	1.07%

Off-Balance Sheet Credit Related Financial Instruments

In the ordinary course of business, the Company has entered into commitments to extend credit, including commercial letters of credit, standby letters of credit, and deposit account overdraft privilege. Such financial instruments are recorded when they are funded.

Premises and Equipment
Land is carried at cost. Buildings and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization expenses are computed using the straight-line method over the estimated useful lives of the related assets or lease terms, whichever is less. Asset lives range from 3-7 years for furniture and equipment and 10-31 years for land improvements and buildings.

Intangible Assets
Intangible assets with estimable useful lives are amortized  over  their  respective  estimated  useful  lives to their estimated  residual values,  and periodically reviewed for impairment.

As of March 31, 2006, the Company had identifiable intangible assets consisting of unrecognized prior service costs of the Company’s supplemental retirement plan (minimum pension liabilities).  These intangible assets are amortized on a straight-line basis over eight years.

11

The following table summarizes the Company’s minimum pension liability intangible as of March 31, 2006 and December 31, 2005.

	December 31,			March 31,
(in thousands)	2005	Additions	Reductions	2006
Minimum pension liability intangible	$734	-	(26)	$708

Income Taxes
The Company's accounting for income taxes is based on an asset and liability approach. The Company recognizes the amount of taxes payable or refundable for the current year, and deferred tax assets and liabilities for the future tax consequences that have been recognized in its financial statements or tax returns. The measurement of tax assets and liabilities is based on the provisions of enacted tax laws.

Stock-Based Compensation

On  January  1, 2006 the  Company  adopted  Statement  of  Financial  Accounting Standards No. 123 (revised  2004),  Share-Based  Payment (SFAS 123R),  using the modified-prospective   transition   method.   Under  this   transition   method, compensation  cost recognized  during the quarter ended March 31, 2006 includes: (a) compensation  cost for all share-based  awards granted prior to, but not yet vested as of, January 1, 2006,  based on the  grant-date  fair value and related service period estimates in accordance with the original  provisions of SFAS 123 and (b)  compensation  cost for all  share-based  awards  granted  subsequent to January 1, 2006,  based on the grant-date fair value and related service periods estimated in accordance  with the prov isions of SFAS 123R.  Under the provisions of the  modified-prospective  transition  method,  results for the three  months ended March 31, 2005 have not been restated. Historically, stock options are the only type of share-based award granted by the Company.

Prior to the adoption of SFAS 123R, the Company used the intrinsic  value method to account for its stock  option plans (in  accordance  with the  provisions  of Accounting  Principles Board Opinion No. 25).  Intrinsic value is the difference between share fair market value and option  exercise  price.  Under this method, compensation  expense was recognized for awards of options to purchase shares of common stock to employees under compensatory plans only if the fair market value of the stock at the option grant date (or other  measurement date, if later) was greater  than the amount the  employee was required to pay to acquire the stock. Statement of Financial  Accounting Standards No. 123, Accounting for Stock-Based Compensation  (SFAS 123),  permitted  companies to continue  using the intrinsic value  method or to adopt a fair value based &n bsp;method to account for stock option plans.  The fair value based method would have resulted in the  recognition,  as expense over the vesting period, of the fair value of all stock-based  awards on the date of grant.

SFAS 123R  clarifies  and expands  the  guidance  in SFAS 123  in several  areas, including  measuring fair value and attributing  compensation  cost to reporting periods. SFAS 123R includes a requirement to: (a) estimate forfeitures of share-based awards at the date of grant,  (b) expense  share-based  awards  granted to retirement   eligible   employees  and  those  employees  with   non-substantive non-compete agreements  immediately,  (c) attribute compensation costs of share-based  award  grants  to  the  stated  future  vesting  period,   (d)  recognize compensation cost of all share-based awards based upon the grant-date fair value (including pre-2006 options).

The Company did not recognize  any gain or loss  resulting  from the  cumulative effect of a change in accounting principle upon adoption of SFAS 123R on January 1, 2006. Based on the stock-based compensation awards outstanding as of December 31,  2005,  for which the  requisite  service  was not fully  rendered  prior to January 1,  2006,  and any  subsequent  option grants as of March 31, 2006,  the Company expects to recognize total pre-tax  compensation  cost of  approximately

$563,000  related to  outstanding  stock option  grants,  of which  $85,000 was recognized  in the first  quarter of 2006,  in  accordance  with the  accounting requirements  of  SFAS 123R.  The  after-tax  effect of adopting SFAS 123R was a reduction of net income of $71,000, and a reduction in diluted  earnings per  share  of  $0.02,  for  the  first  quarter of 2006.  Future  levels  of  compensation  cost  recognized   related  to stock-based   compensation   awards  may  be  impacted  by  new  awards   and/or modifications, repurchases and cancellations of existing awards before and after the adoption SFAS 123R.

12

For the  three  months  ended  March  31,  2005, had  compensation  cost for  the Company’s option plans been determined using the fair-value method of SFAS 123, the  Company’s  net income and earnings per share would have been reduced to the

pro forma amounts indicated below:

(in thousands, except per share amounts)
Net income	As reported	$1,462
	Pro forma	$1,388
Basic earnings per share	As reported	$0.36
	Pro forma	$0.34
Diluted earnings per share	As reported	$0.34
	Pro forma	$0.33
Stock-based employee compensation
cost, net of related tax effects,	As reported	$0
included in net income	Pro forma	$74

The fair value of each option  grant is estimated on the date of grant using the Black-Scholes option-pricing model.

In February 2002, the Company  adopted the North Bay Bancorp 2002 Stock Option Plan (2002 Plan) covering officers,  employees,  directors, and certain independent contractors of the Company.  Under the 2002 Plan,  the option price cannot be less than the fair market  value of the  Common  Stock at the date of grant  except  in the case of substitute options. Options for the 2002 Plan expire no later than the tenth anniversary of the grant date.   Vesting   schedules  under  the  2002  Plan  are  determined individually for each grant.

As of March 31, 2006,  options for the  purchase of 236,540 remained available for grant under the 2002 Plan. Shares

issued  under the  Company’s  option  plans are "new issue"  shares  rather than treasury shares.

Stock  option  activity  for the three  months  ended March 31, 2006 and 2005 is summarized in the following tables:

					Weighted	Weighted

During the three  months ended March 31, 2006,  the  intrinsic  value of options exercised  and the  fair  value of  options  that  vested  were  $343,000  and $85,000,  respectively.  No options were granted  during the three months ended March 31, 2006.

During the three  months ended March 31, 2005,  the  intrinsic  value of options exercised  and the fair value of options that vested were $1,023,000 and $123,000, respectively.  No options were granted  during the three months ended March 31, 2005.

The total  intrinsic value of stock options  exercised  during the quarter ended March 31, 2006 was $343,000 for which no  compensation  costs were  previously recognized nor tax benefits  recognized in equity upon  issuance.  Cash received from the exercise of stock options during the three months ended March 31, 2006 totaled $233,000.

The following table shows the number,  weighted-average  exercise price, and the weighted  average  remaining  contractual life of options  outstanding, and the number and  weighted-average exercise price of options  exercisable as of March 31, 2006 by range of exercise price:

The 175,979 options that are not currently  exercisable as of March 31, 2006 are expected to vest, on a weighted-average basis, over the next 1.63 years, and the Company is expected to recognize $478,000 of compensation costs related to these

options as they vest.

Earnings Per Common Share

Basic Earnings per Share (EPS) is computed by dividing net income by the weighted average common shares outstanding. Diluted EPS is computed by dividing net income by weighted average common shares outstanding including the dilutive effects of potential common shares (e.g. stock options).

The following table reconciles the numerator and denominator of the Basic and Diluted earnings per share computations:

	(In 000's except share data)
	Net Income	Weighted Average Shares	Per-Share Amount
	For the three months ended March 31, 2006
Basic earnings per share	1,715	4,111,968	$0.42
Dilutive effect of stock options		163,625
Diluted earnings per share		4,275,593	$0.40
	For the three months ended March 31, 2005
Basic earnings per share	1,462	4,041,189	$0.36
Dilutive effect of stock options		203,098
Diluted earnings per share		4,244,287	$0.34

Comprehensive Income

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income.

15

The components of accumulated other comprehensive loss, included in shareholders' equity, are as follows:

	March 31,	December 31,
(in thousands)	2006	2005
Net unrealized (loss) gain on available-for-sale securities	$(2,247)	$(1,956)
Tax effect	934	813
Unrealized holding (losses) gains on available-for-sale securities, net of tax	(1,313)	(1,143)
Minimum pension liability	(559)	(573)
Tax effect	232	238
Minimum pension liability, net of tax	(327)	(335)
Accumulated other comprehensive loss	$(1,640)	$(1,478)

Retirement Plans

The Company has supplemental retirement plans covering directors and key executives.  These plans are non-qualified defined benefit plans and the Company’s obligations under the plans are unsecured and unfunded.  The Company has purchased insurance on the lives of the participants and intends to use the cash values of these policies to pay the retirement obligations.

The following table sets forth the net periodic benefit cost recognized for the plans:

	Three Months Ended
	March 31,	March 31,
(in thousands)	2006	2005
Components of net periodic benefits cost:
Service cost - benefits earned during the period	$32	$24
Interest cost on projected benefit obligation	33	23
Amortization of prior service cost	26	19
Amortization of unrecognized loss	13	9
Net periodic benefit cost	$104	$75

During the three months ended March 31, 2006 and 2005, the Company paid out as benefits $9,000 and $8,000, respectively, to participants under the plans.  For the year ending December 31, 2006, the Company expects to pay out as benefits $36,000 to participants under the plans.

Recent Accounting Pronouncements

In December 2004, the Financial  Accounting  Standards  Board (FASB) issued FASB Statement of Financial Accounting Standards No. 123 (revised 2004),  Share-Based Payment (SFAS 123R),  which replaces SFAS No. 123,  Accounting  for  Stock-Based Compensation, (SFAS 123) and supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees.  SFAS 123R requires all share-based  payments to employees, including  grants of employee stock  options,  to be recognized in the financial statements based on their fair values beginning with the first interim reporting period of the Company’s  fiscal year beginning  after June 15, 2005,  with early adoption encouraged.  The pro forma disclosures  previously permitted under SFAS 123 no longer are an alternative  to financial  statement  recognition.  The Company  ado pted  SFAS 123R on  January  1, 2006  using a  modified  version  of prospective  application  ("modified prospective  application").  Under modified prospective  application,  as it is applicable to the Company, SFAS 123R applies to new grants and to grants modified, repurchased, or cancelled after January 1, 2006.  Additionally,  compensation  cost for the portion of grants for which the requisite  service has not been  rendered  (generally  referring  to  non-vested grants) that are  outstanding  as of January 1, 2006 must be  recognized  as the remaining  requisite service is rendered during the period of and/or the periods after the adoption of SFAS 123R. The attribution of compensation  cost for those earlier grants will be based on the same method and on the same  grant-date fair values  previously  determined  for  the  pro  forma  disclosures  required  for companies that did not adopt the fair value  accounting  method for  stock-based employee compensation.

16

The Company did not recognize  any gain or loss  resulting  from the  cumulative effect of a change in accounting principle upon adoption of SFAS 123R on January 1, 2006. Based on the stock-based compensation awards outstanding as of December 31,  2005,  for which the  requisite  service  was not fully  rendered  prior to January 1, 2006,  and any  subsequent  option  grants as of March 31, 2006,  the Company expects to recognize total pre-tax  compensation  cost of  approximately $563,000  related to  outstanding  stock option  grants,  of which  $85,000 was recognized  in the first  quarter of 2006,  in  accordance  with the  accounting requirements  of SFAS 123R.  The  after-tax  effect of adopting  SFAS 123R was a reduction of net income of $71,000, and a reduction in diluted  earnings per  share  of  $0.02,  for  the  first  quarter  of  2006.  Future  levels  of  compensation  cost  recognized   related  to stock-based   compensation   awards  may  be  impacted  by  new  awards   and/or modifications, repurchases and cancellations of existing awards before and after the adoption SFAS 123R.

Reclassifications

Certain amounts previously reported in the 2005 financial statements have been reclassified to conform to the 2006 presentation.  These reclassifications did not affect previously reported net income or  total shareholders’ equity.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

As North Bay Bancorp (the "Company") has not commenced any business operations independent of The Vintage Bank (the "Bank"), the following discussion pertains primarily to the Bank. Average balances, including such balances used in calculating certain financial ratios, are generally comprised of average daily balances for the Company.

Critical Accounting Policies and Estimates

The Company's discussion and analysis of its financial condition and results of operations are based upon the Company's condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to the adequacy of the allowance for loan losses, investments, income taxes, contingencies and supplemental retirement plan liabilities. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the ca rrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. (See Note 1 to Condensed Consolidated Financial Statements – Allowance for Loan Losses).

Results of Operations
The following discussion and analysis is designed to provide a better understanding of the significant changes and trends related to the Company and the Bank's financial condition, operating results, asset and liability management, liquidity and capital resources and should be read in conjunction with the Condensed Consolidated Financial Statements of the Company and the Notes thereto.

Following is a summary of the components of net income for the periods indicated (dollars in thousands):

	Three months ended
	March 31,
	2006	2005
Net Interest Income	$7,374	$6,624
Provision for loan losses	100	185
Noninterest income	1,047	956
Noninterest expense	5,779	5,035
Provision for income taxes	827	898
Net income	1,715	1,462

The Company had quarterly earnings of $1,715,000, or $0.40 per diluted share, for the three months ended March 31, 2006. These results represent a 17.6% increase from the $0.34 earnings per diluted share reported for the three months ended March 31, 2005 on earnings of $1,462,000. The improvement in results from the year-ago quarter was due to a $750,000 (11.3 %) increase in net interest income to $7,374,000, an $85,000 (45.9%) decrease in the provision for loan losses to $100,000, and a $91,000 (9.5%) increase in noninterest income to $1,047,000. These contributing factors were partially offset by a $744,000 (14.8%) increase in noninterest expense to $5,779,000 for the quarter ended March 31, 2006.

Net Interest Income

Following is a summary of the components of net interest income for the periods indicated (dollars in thousands):

	Three months ended
	March 31,
	2006	2005
Interest income	$8,953	$7,676
Interest expense	(1,579)	(1,052)
Net interest income	$7,374	$6,624
Average interest-earning assets	$546,143	$503,767
Net interest margin (FTE)	5.56%	5.38%

Net interest income represents the amount by which interest earned on earning assets (primarily loans and investments) exceeds the amount of interest paid on deposits.   Net interest income is a function of volume, interest rates and level of non-accrual loans.  Non-refundable loan origination fees are deferred and amortized into income over the life of the loan.  

Net interest income before the provision for loan losses was $7,374,000 and $6,624,000 for the three months ended March 31, 2006 and March 31, 2005, respectively. These results equate to an 11.3% increase in net interest income for the first quarter of 2006 compared to the first quarter of 2005.

Interest and Fee Income
Interest and fee income for the first quarter of 2006 increased $1,277,000 (16.6%) from the first quarter of 2005. The increase was the net effect of a $42,376,000 (8.4%) increase in average balances of interest-earning assets to $546,143,000 and a 51 basis point increase in the yield on those average interest-earning assets to 6.74%. The growth in interest-earning assets was comprised of a $32,334,000 (8.3%) increase in average loan balances to $420,328,000 that was partially offset by a decrease of $15,873,000 (90%) in average balances of Federal funds sold to $1,772,000. The increase in the yield on average interest-earning assets was mainly due to the overall increase in market rates during the first quarter of 2006 compared with the first quarter of 2005.

Interest Expense

Interest expense increased $527,000 (50%) to $1,579,000 in the first quarter of 2006 compared to the year-ago quarter. The average balance of interest-bearing liabilities increased $14,923,000 (4.0%) to $386,751,000 in the first quarter compared to the year-ago quarter. The increase in the average balance of interest-bearing liabilities was concentrated in time deposits (up $5,129,000 or 6.7%), interest-bearing demand deposits (up $4,908,000 or 2.2%), and other borrowings (up $4,154,000 or 21.9%).  In addition, the average balance of noninterest-bearing deposits increased $14,681,000 (10.7%) from the year-ago quarter. The average rate paid on interest-bearing liabilities in the quarter ended March 31, 2006 increased 51 basis points to 1.66% compared to the year-ago quarter. The average rate paid for all categories of interest-bearing liabilities increased from the average rate paid in the year-ago quarter as a result of general market interest rate changes.

20

Net Interest Margin (FTE)

The following table summarizes the components of the Company’s net interest margin for the periods indicated:

	Three months ended
	March 31,
	2006	2005
Yield on interest-earning assets	6.74%	6.23%
Rate paid on interest-bearing liabilities	1.66%	1.15%
Net interest spread	5.08%	5.08%
Impact of all other net noninterest-bearing funds	0.48%	0.30%
Net interest margin	5.56%	5.38%

The net interest margin in the first quarter of 2006 increased 18 basis points compared to the first quarter of 2005. This increase in net interest margin was mainly due to the 18 basis point increase in the impact of all other net noninterest-bearing funds.

Summary of Average Balances, Yields/Rates and Interest Differential

The following tables present, for the periods indicated, information regarding the Company's consolidated average assets, liabilities and shareholders' equity, the amounts of interest income from average interest-earning assets and resulting yields, and the amount of interest expense paid on interest-bearing liabilities. Average loan balances include nonperforming loans. Interest income includes proceeds from loans on nonaccrual loans only to the extent cash payments have been received and applied to interest income. Yields on securities have been adjusted upward to reflect the effect of income thereon exempt from federal income taxation at the current statutory tax rate (dollars in thousands).

Noninterest Income
The following table summarizes the components of noninterest income for the periods indicated.

	Three months ended
	March 31,
(in thousands)	2006	2005
Service charges and other fees	$500	$523
Increase in cash value of life insurance	$105	$91
Other income	442	342
Total noninterest income	$1,047	$956

Noninterest income for the three months ended March 31, 2006 increased $91,000, or 9.5%, compared to the the same period in the prior year.  Increases in ATM fees, commissions on investment products sold and earnings on non-marketable equity securities contributed to the increase in other income.

Noninterest Expense

The following table summarizes the components of noninterest expense for the periods indicated.

Details of noninterest expense are as follows:

	Three months ended
	March 31, 2006
(in thousands)	2006	2005
Salaries and related benefits	$3,206	$2,724
Occupancy	475	394
Equipment	479	547
Professional services	520	486
Business promotion	250	134
Stationery & supplies	149	124
Insurance	63	71
Other	637	555
Total	$5,779	$5,035

Noninterest expense for the first quarter of 2006 increased $744,000 (14.8%) to $5,779,000 from $5,035,000 in the first quarter of 2005.  The $482,000 (17.7%) increase in salaries and related benefits expense during 2006 compared with 2005 was due to new additions and changes to the senior management team, staffing increases in the risk management, compliance and internal audit functions and $85,000 of stock option expense recorded in the first quarter of 2006 in accordance with SFAS 123R.  The 21% increase in occupancy is due to rent increases on leased premises and higher vacancy rates in a building owned by the Company.

Provision for Income Tax
The effective tax rate for the three months ended March 31, 2006 was 32.5% and reflects a decrease from 38.1% for the three months ended March 31, 2005.  The lower effective tax rate during the first quarter of 2006 was due to a $2 million investment in an affordable housing bond issue near year-end 2005 that generates income tax credits for the Company.

BALANCE SHEET

Total assets as of March 31, 2006 were $611,310,000 compared with $602,697,000 as of year-end 2005, representing a 1.4% increase.  Total deposits declined from $516,393,000 at December 31, 2005 to $509,891,000 at March 31, 2006.  Total loans, net of the allowance for loan losses, grew to $427,169,000 at March 31, 2006 compared to $409,504,000 at December 31, 2005, representing a 4.3% increase.  Investment securities decreased from $124,510,000 at December 31, 2005 to $122,247,000 at March 31, 2006.

Liquidity

The Company's liquidity is determined by the level of assets (such as cash, Federal funds sold, and investments in unpledged marketable securities) that are readily convertible to cash to meet customer withdrawals and credit commitments.  Management reviews the Company’s liquidity position on a regular basis to ensure that it is adequate to meet projected loan funding and potential withdrawal of deposits.  The Company has a comprehensive Asset/Liability Management and Liquidity Policy, which it uses to determine adequate liquidity.  As of March 31, 2006 liquid assets were 20% of total assets, compared with 26% as of March 31, 2005 and is in excess of the minimum limits set in the the Company’s liquidity policy.

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

The Company’s exposure to market risk exists primarily in interest rate risk in the balance sheet.  The objective of market risk management is to mitigate an undue adverse impact on earnings and capital arising from changes in interest rates and other market variables. This risk management objective supports the Company’s broad objective of enhancing shareholder value, which encompasses stable earnings growth over time.

The Board of Directors, through its Asset & Liability Management Committee (ALCO), approves the ALM Policy, which governs the management of market risk and liquidity.  ALCO is responsible for ongoing management of interest rate risk as well as liquidity risk, including formulation of risk management strategies.  The Chief Financial Officer is primarily responsible for the implementation of risk management strategies approved by ALCO and for operating management of market risk through the funding and investment activities of the Company.

The Company manages the market risk associated with our asset and liability management activities as described below.

Interest Rate Risk Management

ALCO monitors interest rate risk quarterly through a variety of modeling techniques that are used to quantify the sensitivity of Net Interest Income (NII) and Economic Value of Equity (EVE) to changes in interest rates.  In managing interest rate risk, ALCO monitors NII sensitivity over a twelve-month time horizon and in response to a variety of interest rate changes.  The Company’s NII policy measure involves a simulation of  NII in which the Company estimates the impact that proportional shifts in the yield curve would have on earnings over a twelve-month horizon, given the projected balance sheet profile.

25

 Simulation of NII is the primary tool used to measure the Company’s interest rate risk.  The NII simulations use a twelve-month projected balance sheet in order to model the impact of interest rate changes. Assumptions are made to model the future behavior of deposit rates and loan spreads based on management’s outlook and historical experience.

At March 31, 2006, the NII simulation showed modest asset-sensitivity to proportional rate shifts. A +200 basis point proportional shift would raise twelve-month NII by 2. 59 percent, while a similar downward shift would reduce it by 2. 58 percent.  Continued enhancements to the Company’s interest rate risk modeling may make prior-year comparisons of NII less meaningful.

NII Simulation

	Estimated Change in
	NII
Change in Interest Rates (Basis Points)	(as a % of "flat" NII)
+ 300	3.89%
+ 200	2.59%
+ 100	1.29%
+ 0 (flat)	0.00%
- 100	(1.29%)
- 200	(2.58%)
- 300	(3.86%)

In addition to NII, the Company measures the sensitivity of EVE to interest rate shocks.  EVE is reviewed and monitored for its compliance with ALCO limits.  Consistent with the projected asset-sensitivity of earnings over time, the Company’s EVE shows asset-sensitivity as well.

Management believes that, together, our NII and EVE simulations provide management with a reasonably comprehensive view of the sensitivity of our operating results and value profile to changes in interest rates, at least over the measurement horizon.  However, as with any financial model, the underlying assumptions are inherently uncertain and subject to refinement as modeling techniques and theory improve and historical data becomes more readily accessible. Consequently, the simulation models cannot predict with certainty how rising or falling interest rates might impact net interest income. Actual and simulated results will differ to the extent there are differences between actual and assumed interest rate changes, balance sheet volumes, and management strategies, among other factors.

In general, the core balance sheet is relatively asset sensitive, meaning that investments and loans generally re-price more quickly than core deposits. In managing the interest sensitivity of the balance sheet, the Company uses the investment securities portfolio as the primary tool to adjust the risk profile.

At March 31, 2006 and December 31, 2005, the securities available for sale portfolio totaled $122.2 and $124.5 million, respectively.  The estimated effective duration of the available for sale portfolio was 3.1 at March 31, 2006, compared to 3.0 at December 31, 2005.

Effective duration is a measure of price sensitivity of a bond portfolio to immediate parallel shifts in interest rates. An effective duration of  3.1 suggests an expected price decline of approximately 3.1 percent for an immediate one percent increase in interest rates.
