NBT BANCORP INC. and Subsidiary NOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS March 31, 2001 BASIS OF PRESENTATION The accompanying unaudited interim consolidated financial statements include the accounts of NBT Bancorp Inc. (the Registrant) and its wholly-owned subsidiaries, NBT Bank, N.A. (NBT) and NBT Financial Services, Inc. All intercompany transactions have been eliminated in consolidation. Amounts in the prior period financial statements are reclassified whenever necessary to conform to current period presentation. The consolidated balance sheet at December 31, 2000 has been derived from audited consolidated financial statements at that date. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to FORM 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three month period ended March 31, 2001 are not necessarily indicative of the results that may be expected for the year ending December 31, 2001. For further information, refer to the consolidated financial statements and footnotes thereto included in the Registrant's annual report on FORM 10-K for the year ended December 31, 2000 and notes thereto referred to above. The March 31, 2000 unaudited interim consolidated financial statements have been restated to give effect to the merger with Pioneer American Holding Company Corp., which closed on July 1, 2000 and was accounted for as a pooling-of-interest. EARNINGS PER SHARE Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders 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 or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. All share and per share data has been adjusted retroactively for stock dividends and splits. The following is a reconciliation of basic and diluted earnings per share for the periods presented in the consolidated statements of income. -------------------------------------------------------------------------------------------------------------- Three months ended March 31, 2001 2000 -------------------------------------------------------------------------------------------------------------- (in thousands, except per share data) Basic EPS: Weighted average common shares outstanding 23,651 23,198 Net income available to common shareholders $ 7,638 $ 5,280 -------------------------------------------------------------------------------------------------------------- Basic EPS $ 0.32 $ 0.23 -------------------------------------------------------------------------------------------------------------- Diluted EPS: Weighted average common shares outstanding 23,651 23,198 Dilutive potential common stock 217 148 -------------------------------------------------------------------------------------------------------------- Weighted average common shares and common share equivalents 23,868 23,346 Net income available to common shareholders $ 7,638 $ 5,280 -------------------------------------------------------------------------------------------------------------- Diluted EPS $ 0.32 $ 0.23 -------------------------------------------------------------------------------------------------------------- -8-

There were 410,385 stock options for the quarter ended March 31, 2001 and 765,158 stock options for the quarter ended March 31, 2000 that were not considered in the calculation of diluted earnings per share since the stock options' exercise price was greater than the average market price during these periods. MERGERS AND ACQUISITIONS On February 17, 2000, the Company consummated a merger, whereby Lake Ariel Bancorp, Inc. (Lake Ariel) and its subsidiaries were merged with and into the Company with each issued and outstanding share of Lake Ariel exchanged for 0.9961 of a share of NBT common stock. The transaction resulted in the issuance of approximately 5.0 million shares of NBT common stock. Lake Ariel's commercial banking subsidiary was LA Bank, N.A. On July 1, 2000, the Company consummated a merger, whereby Pioneer American Holding Company Corp. (Pioneer Holding Company) and its subsidiary were merged with and into the Company with each issued and outstanding share of Pioneer Holding Company exchanged for 1.805 shares of NBT common stock. The transaction resulted in the issuance of approximately 5.2 million shares of NBT common stock. Pioneer Holding Company's commercial banking subsidiary was Pioneer American Bank, N.A. The Lake Ariel and Pioneer Holding Company mergers qualified as tax-free exchanges and were accounted for as poolings-of-interests. accordingly, these consolidated financial statements have been restated to present the combined consolidated financial condition and results of operations of all companies as if the mergers had been in effect for all periods presented. LA Bank, N.A. and Pioneer American Bank, N.A. were commercial banks headquartered in northeast Pennsylvania with approximately $570 million and $420 million, respectively, in assets at December 31, 1999, and twenty-two and eighteen branch offices, respectively, in five counties. Immediately following the mergers described above, NBT was the surviving holding company for NBT Bank, N.A., LA Bank, N.A., Pioneer American Bank, N.A. and NBT Financial Services, Inc. LA Bank, N.A. effected a name change on November 10, 2000 to Pennstar Bank, N.A. and on December 9, 2000, Pioneer American Bank, N.A. merged into Pennstar Bank, N.A. During the first quarter of 2001, the national bank charter of Pennstar Bank, N.A. was merged into that of NBT Bank, N.A. On May 5, 2000, the Company consummated the acquisition of M. Griffith, Inc., a New Hartford, New York based securities firm offering investment, financial advisory and asset-management services, primarily in the Mohawk Valley region. At that time, M. Griffith, Inc., a full-service broker-dealer and a Registered Investment Advisor, became a wholly-owned subsidiary of NBT Financial Services, Inc. The acquisition was accounted for using the purchase method. As such, both the assets acquired and liabilities assumed have been recorded on the consolidated balance sheet of the Company at estimated fair value as of the date of acquisition. M. Griffith, Inc.'s results of operations are included in the Company's consolidated statement of income from the date of acquisition forward. To complete the transaction, the Company issued approximately 421,000 shares of its common stock, valued at $4.8 million. Goodwill, representing the cost over net assets acquired, was $3.4 million and is being amortized over fifteen years on a straight-line basis. On June 2, 2000, one of NBT's subsidiaries, LA Bank, N.A., purchased two branches from Mellon Bank. Deposits from the Mellon Bank branches were approximately $36.7 million, including accrued interest payable. In addition, the Company received approximately $32.2 million in cash as consideration for net liabilities assumed. The acquisition was accounted for using the purchase method. As such, both the assets acquired and liabilities assumed have been recorded on the consolidated balance sheet of the Company at estimated fair value as of the date of the acquisition. Goodwill, representing the excess of cost over net assets acquired, was $4.3 million and is being amortized over 15 years on the straight-line basis. The branches' results of operations are included in the Company's consolidated statement of income from the date of acquisition forward. On November 10, 2000, Pennstar Bank, N.A. purchased six branches from Sovereign Bank. deposits from Sovereign Bank branches were approximately $96.8 million, including accrued interest payable. Pennstar Bank, N.A. also purchased commercial loans associated with the branches with a net book balance of $42.4 -9-

million. In addition, the Company received $40.9 million in cash consideration for net liabilities assumed. The acquisition was accounted for using the purchase method. As such, both the assets acquired and liabilities assumed have been recorded on the consolidated balance sheet of the Company at estimated fair value as of the date of the acquisition. Goodwill, representing the excess of cost over net assets acquired, was $12.7 million and is being amortized over 15 years on a straight-line basis. The branches' results of operations are included in the Company's consolidated statement of income from the date of acquisition forward. On January 2, 2001, the Company announced the signing of a definitive agreement to acquire First National Bancorp, Inc. (FNB) and its wholly owned subsidiary, The First National Bank of Northern New York (FNB Bank). FNB Bank is expected to be merged into NBT Bank, N.A. In the acquisition, shareholders of FNB will receive five shares of NBT common stock for each share of FNB common stock. NBT is expected to issue approximately 1.0 million shares of common stock, with a total value of approximately $15 million, based on the closing price of NBT stock on January 2, 2001. The acquisition is structured to be tax-free to shareholders of FNB and will be accounted for using the purchase method of accounting. The merger received the approval of FNB shareholders at a meeting held on April 6, 2001. Approval of the merger of the First National Bank of Northern New York into NBT Bank was received from the Office of the Comptroller of the Currency earlier the same week. The merger is expected to close in late May with the conversion of the FNB branches to the NBT Bank system slated to take place during the summer months. At December 31, 2000, FNB had consolidated assets of $114.2 million, deposits of $102.8 million and equity of $10.0 million. FNB Bank operates six full-service banking locations in New York State's North Country. NBT also announced a plan to repurchase in the market approximately 1 million shares of its common stock specifically for issuance in the transaction. NEW ACCOUNTING PRONOUNCEMENTS The Company adopted the provisions of SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," effective January 1, 2001. This statement establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. It requires that an entity recognize all derivatives as either assets or liabilities in the balance sheet and measure those instruments at fair value. Changes in the fair value of the derivative financial instruments are reported in either net income or as a component of comprehensive income. Consequently, there may be increased volatility in net income, comprehensive income, and stockholders' equity on an ongoing basis as a result of accounting for derivatives in accordance with SFAS No. 133. Special hedge accounting treatment is permitted only if specific criteria are met, including a requirement that the hedging relationship be highly effective both at inception and on an ongoing basis. Accounting for hedges varies based on the type of hedge - fair value or cash flow. Results of effective hedges are recognized in current earnings for fair value hedges and in other comprehensive income for cash flow hedges. Ineffective portions of hedges are recognized immediately in earnings and are not deferred. The adoption of SFAS No. 133 by The Company on January 1, 2001 did not have a material effect on the Company's consolidated financial position or results of operations. In September 2000, the FASB issued SFAS No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities", a replacement of SFAS No. 125. SFAS 140 addresses implementation issues that were identified in applying SFAS No. 125. This statement revises the standards for accounting for securitizations and other transfers of financial assets and collateral and requires certain disclosures, but it carries over most of SFAS No. 125 provisions without reconsideration. SFAS 140 is effective for transfers and servicing of financial assets and extinguishments of liabilities occurring after March 31, 2001. SFAS No. 140 is effective for recognition and reclassification of collateral and for disclosures relating to securitization transactions and collateral for fiscal years ending after December 15, 2000. This statement is to be applied prospectively with certain exceptions. Other than those exceptions, earlier or retroactively application is not permitted. The adoption of SFAS No. 140 did not have a material effect on the Company's consolidated financial statements. -10-

FORWARD LOOKING STATEMENTS Certain statements in this filing and future filings by the Company with the Securities and Exchange Commission, in the Company's press releases or other public or shareholder communications, or in oral statements made with the approval of an authorized executive officer, contain forward-looking statements, as defined in the Private Securities Litigation Reform Act.

OVERVIEW The Company earned net income of $7.6 million ($0.32 diluted earnings per share) for the three months ended March 31, 2001 compared to net income of $5.3 million ($0.23 diluted earnings per share) for the three months ended March 31, 2000. Recurring net income, which excludes the after-tax effect of costs related to merger and acquisition activity, reorganizations, net securities gains, gain on sale of a branch building, and certain deposit overdraft write-offs considered to be nonrecurring was $7.8 million ($0.33 diluted earnings per share) for the first quarter of 2001 compared to $6.4 million ($0.27 diluted earnings per share) of recurring net income for the first quarter of 2000. The quarter to quarter increase in recurring net income from 2000 to 2001 was primarily the result of an increase in net interest income, an increase in noninterest income, excluding net securities gains and the gain on sale of a branch building along -11-

with a decrease in the provision for loan losses, offset in part by an increase in noninterest expense, excluding costs related to merger and acquisition activity, reorganizations and deposit overdraft write-offs. Table 1 depicts several measurements of performance on an annualized basis. Returns on average assets and equity measure how effectively an entity utilizes its total resources and capital, respectively. Both the return on average assets and the return on average equity ratios increased for the quarter compared to the same period a year previous. Net interest margin, net federal taxable equivalent (FTE) interest income divided by average interest-earning assets, is a measure of an entity's ability to utilize its earning assets in relation to the cost of funding. Interest income for tax-exempt securities and loans is adjusted to a taxable equivalent basis using the statutory Federal income tax rate of 35%. TABLE 1 PERFORMANCE MEASUREMENTS -------------------------------------------------------------------------------------------- FIRST First QUARTER Quarter 2001 2000 -------------------------------------------------------------------------------------------- Return on average assets 1.19% 0.88% Return on average equity 14.55% 11.10% Net interest margin (FTE) 4.21% 4.25% -------------------------------------------------------------------------------------------- NET INTEREST INCOME Net interest income is the difference between interest income on earning assets, primarily loans and securities, and interest expense on interest-bearing liabilities, primarily deposits and borrowings. Net interest income is affected by the interest rate spread, the difference between the yield on earning assets and cost of interest-bearing liabilities, as well as the volumes of such assets and liabilities. Net interest income is one of the major determining factors in a financial institution's performance as it is the principal source of earnings. Table 2 represents an analysis of net interest income on a federal taxable equivalent basis. Federal taxable equivalent (FTE) net interest income increased $1.1 million during the first quarter of 2001 compared to the same period of 2000. This increase can be attributed to an increase in average earning assets, the result of continued loan growth, as well as an increase in the yield earned on average earning assets, offset by increases in average interest bearing liabilities and the rates paid on those interest bearing liabilities. Total FTE interest income increased $3.7 million compared to first quarter 2000, a result of the previously mentioned increase in average earning assets as well as a 20 basis point increase in the yield earned on those earning assets. The increase in the yield on earning assets can be primarily attributed to a 14 basis point increase in the yield on the loan portfolio. During the same time period, total interest expense increased $2.6 million, the result of a $126.5 million increase in average interest bearing liabilities between reporting periods as well as a 27 basis point increase in their cost. Driving the increase in the cost of funds was a 58 basis point increase in the cost of time deposits. The increase in the cost of funds resulted in a 7 basis point decline in the interest rate spread. Another important performance measurement of net interest income is the net interest margin. This is computed by dividing annualized FTE net interest income by average earning assets for the period. Net interest margin decreased to 4.21% for first quarter 2001, down from 4.25% for the comparable period in 2000. The decrease in the net interest margin can be attributed to the previously mentioned decrease in the interest rate spread driven by the increase in the cost of interest bearing liabilities exceeding the increase in yields on earning assets. -12-

The adequacy of the allowance for loan losses is continuously monitored. It is assessed for adequacy using a methodology designed to ensure the level of the allowance reasonably reflects the loan portfolio's risk profile. It is evaluated to ensure that it is sufficient to absorb all reasonably estimable credit losses inherent in the current loan portfolio. For purposes of evaluating the adequacy of the allowance, the Company considers a number of significant factors that affect the collectibility of the portfolio. For individually analyzed loans, these include estimates of loss exposure, which reflect the facts and circumstances that affect the likelihood of repayment of such loans as of the evaluation date. For homogeneous pools of loans, estimates of the Company's exposure to credit loss reflect a thorough current assessment of a number of factors, which could affect collectibility. These factors include: past loss experience; the size, trend, composition, and nature; changes in lending policies and procedures, including underwriting standards and collection, charge-off and recovery practices; trends experienced in nonperforming and delinquent loans; current economic conditions in the Company's market; portfolio concentrations that may affect loss experienced across one or more components of the portfolio; the effect of external factors such as competition, legal and regulatory requirements; and the experience, ability, and depth of lending management and staff. In addition, various regulatory agencies, as an integral component of their examination process, periodically review the Company's allowance for loan losses. Such agencies may require the Company to recognize additions to the allowance based on their judgment about information available to them at the time of their examination, which may not be currently available to management. After a thorough consideration and validation of the factors discussed above, required additions to the allowance for loan losses are made periodically by charges to the provision for loan losses. These charges are necessary to maintain the allowance at a level which management believes is reasonably reflective of overall inherent risk of probable loss in the portfolio. While management uses available information to recognize losses on loans, additions to the allowance may fluctuate from one reporting period to another. These fluctuations are reflective of changes in risk associated with portfolio content -14-

and/or changes in management's assessment of any or all of the determining factors discussed above. The allowance for loan losses to outstanding loans at March 31, 2001 was 1.40% compared to 1.34% at March 31, 2000. Management considers the allowance for loan losses to be adequate based on evaluation and analysis of the loan portfolio. Table 3 reflects changes to the allowance for loan losses for the periods presented. The allowance is increased by provisions for losses charged to operations and is reduced by net charge-offs. Charge-offs are made when the collectability of loan principal within a reasonable time is unlikely. Any recoveries of previously charged-off loans are credited directly to the allowance for loan losses. The provision for loan losses was approximately $1.0 million, $3.3 million, and $1.5 million for the three months ended March 31, 2001, December 31, 2000, and March 31, 2000, respectively. The increase in the provision during the fourth quarter of 2000 was primarily the result of significant loan growth, primarily in the higher risk commercial and consumer type loans, an increase in nonperforming loans, and an increase in net charge-offs. The increase in nonperforming loans was primarily the result of a continuing process of integrating newly acquired banks into the Company given the Company's more conservative approach to identifying and resolving nonperforming loans. The fourth quarter provision for loan losses reflected the loan portfolio's increased inherent risk of loss related to the significantly increased nonperforming loans at December 31, 2000, the increased net charge-offs during the quarter ended December 31, 2000, and an anticipated net charge-off level in 2001 higher than previously experienced. As expected, net charge-offs in the first quarter of 2001 (approximately $1.1 million) were significantly higher than the net charge-offs in the first quarter of 2000 (approximately $0.5 million), however they were reduced from the fourth quarter of 2000 (approximately $2.1 million). As noted above, the increased net charge-offs in the first quarter of 2001 as compared to the first quarter of 2000 were anticipated and primarily addressed in the provision for loan losses for the fourth quarter of 2000. Nonperforming loans at March 31, 2001 totaled approximately $22.5 million, representing a significant increase from nonperforming loans of approximately $12.6 million at March 31, 2000. However, as mentioned above, this increase was the result of the Company's fourth quarter of 2000 integration effort. Nonperforming loans at December 31, 2000 were approximately $21.5 million. Accordingly, the provision for loan losses in the first quarter of 2001 of approximately $1.0 million was lower than the provision of approximately $1.5 million in the first quarter of 2000, despite the increase in net loan charge-offs and nonperforming loans which were primarily addressed through higher provision for loan losses in the fourth quarter of 2000. Additionally, the Company's loan growth slowed during the first quarter of 2001 when compared to both the fourth and first quarters of 2000, which also contributed to the reduction in the provision for loan losses in the first quarter of 2001 as compared to both the fourth and first quarters of 2000. However, the integration process described above is continuing. As this integration process continues, management expects that additional credit risk may be identified, which may result in future charge-offs being higher than anticipated. Also, additional non-accrual loans may be identified as a result of the continuing integration process. An increase in charge-offs and non- accrual loans that is greater than anticipated could result in an increase in the provision for loan losses in future periods. -15-

Noninterest income, exclusive of net securities gains and the gain on the sale of a branch building, totaled $6.2 million for the first quarter of 2001 compared to $4.2 million for the first quarter of 2000. The $2.0 million, or 47.1%, increase in 2001 is primarily the result of an increase in broker/dealer fees of approximately $1.0 million, the direct result of the Company's acquisition of M. Griffith, Inc., a full service broker/dealer and registered investment advisor, on May 5, 2000. In addition, service charges on deposit accounts increased $0.4 million and other income increased $0.6 million during the first quarter of 2001 compared to the same period in 2000. The increase in service charges on deposit accounts can be attributed to an increase in the number of deposit accounts between reporting periods. NONINTEREST EXPENSE AND OPERATING EFFICIENCY Total noninterest expense, excluding nonrecurring merger, acquisition and reorganization expenses and deposit overdraft write-offs, increased $1.6 million between the quarter ended March 31, 2001 and the same period for 2000. Salaries and employee benefits for the first quarter of 2001 increased $0.6 million compared to the same period of 2000, primarily the result of the addition of M. Griffith in May of 2000. Data processing and communications expense for the first quarter of 2001 experienced a $0.7 million increase compared to the same period in 2000, the result of an expanded communication network and increased transaction volume. Amortization of intangible assets expense for the quarter ended March 31, 2001 experienced a $0.3 million increase compared to the same period in 2000, the result of the previously mentioned Mellon Bank and Soveriegn Bank branch acquisitions, as well as the M. Griffith, Inc. acquisition. One important operating efficiency measure that the Company closely monitors is the efficiency ratio. The efficiency ratio is computed as total noninterest expense (excluding nonrecurring charges) divided by net interest income plus noninterest income (excluding net security gains and losses and nonrecurring income). The efficiency ratio of 57.48% in the first quarter of 2001 was comparable to the efficiency ratio of 57.47% in the same period of 2000. -16-

At March 31, 2001, after payments of certain merger, acquisition and reorganization costs, the Company had a remaining accrued liability for merger, acquisition and reorganization costs as follows: Professional fees $ 158 Data processing 562 Severance 3,096 Branch closings 195 Advertising and supplies 155 Miscellaneous 87 ------------------------------------------------------ Total $ 4,253 ------------------------------------------------------ With the exception of certain severance costs, which will be paid out over a period of time consistent with the respective severance agreements, all of the above liabilities are expected to be paid during 2001. All other categories of noninterest expense remained fairly consistent from the first quarter of 2000 to the first quarter of 2001. INCOME TAXES Income tax expense was $3.8 million for the first quarter of 2001 compared to $3.1 million for the first quarter of 2000. The effective tax rate was 33.0% for the first quarter of 2001 and 36.9% for the same period of 2000. The higher tax rate during 2000 can be attributed to non-deductible merger and acquisition costs as well as a corporate realignment in 2000. SECURITIES Average total securities were $79.9 million less for the first quarter of 2001 than for the same period of 2000. The majority of this decrease was in the available for sale portfolio as the proceeds from the sales and paydowns from the mortgage-backed securities were used to fund the loan growth experienced during 2000. During the first quarter of 2001, the securities portfolio represented 27.7% of average earning assets compared to 33.0% for the first quarter of 2000. At March 31, 2001, the securities portfolio was comprised of 86% available for sale and 14% held to maturity securities. LOANS The Company has continued to experience strong growth in the loan portfolio. Average loan volume for the first quarter of 2001 was $1,719.9 million, or 14.5% greater than the first quarter 2000 average. This growth has been present in all loan categories, with increases in the average commercial, consumer and mortgage portfolios of $139.8 million, $33.2 million and $46.1 million, respectively. The Company has continued to experience an increase in the demand for commercial loans, primarily in the business and real estate categories. The Company does not engage in highly leveraged transactions or foreign lending activities. NONPERFORMING ASSETS Nonperforming assets consist of nonaccrual loans, loans 90 days or more past due, restructured loans and other real estate owned (OREO). Loans are generally placed on nonaccrual when principal or interest payments become ninety days past due, unless the loan is well secured and in the process of collection. Loans may also be placed on nonaccrual when circumstances indicate that the borrower may be unable to meet the contractual principal or interest payments. OREO represents property acquired through foreclosure and is valued at the lower of the carrying amount or fair market value, less any estimated disposal costs. Total nonperforming assets were $23.3 million at March 31, 2001 compared to $22.2 million at December 31, 2000 and $13.6 million at March 31, 2000. The increase since March 31, 2000 can be attributed to a $6.5 million increase in loans 90 days or more past due as well as a $4.0 million increase in nonaccrual loans between reporting periods. These increases were primarily the result integrating newly acquired banks into the Company. -17-

The Company purchased approximately $133.7 million in deposits in conjunction with the purchase of branches from Mellon Bank and Sovereign Bank in June and November of 2000, respectively. Average total deposits for the quarter ended March 31, 2001 were $2.0 billion compared to $1.8 billion at March 31, 2000. This growth has been present in all deposit categories, with increases in the average demand, savings and time deposits of $31.1 million, $70.7 million and $109.6 million, respectively. The increase in time deposits was primarily the result of the increase in time deposits greater than $100,000, which includes brokered CD's. Brokered CD's were approximately $110.5 million, $130.5 million and $89.4 million at March 31, 2001, December 31, 2000 and March 31, 2000, respectively. Time deposits greater than $100,000 were approximately $470.3 million, $503.8 million and $433.0 million at March 31, 2001, December 31, 2000 and March 31, 2000, respectively. BORROWED FUNDS The Company's borrowed funds consist of short-term borrowings and long-term debt. Average short-term borrowings for the first quarter of 2001 were $107.7 million compared to $150.6 million for the same period of 2000. Average long-term debt for the first quarter of 2001 was $235.8 million compared to $246.8 million for the same period of 2000. The previously mentioned increase in deposits contributed to the decline in average borrowings as it has enabled the Company to pay down a portion of its existing debt. CAPITAL AND DIVIDENDS Stockholders' equity of $217.4 million represents 8.4% of total assets at March 31, 2001, compared with $194.6 million, or 8.0% a year previous, and $208.0 million, or 7.8% at December 31, 2000. The Company does not have a target dividend payout ratio, rather the Board of Directors considers the Company's earnings position and earnings potential when making dividend decisions. As the capital ratios in Table 6 indicate, the Company remains well capitalized. Capital measurements are significantly in excess of regulatory minimum guidelines and meet the requirements to be considered well capitalized for all periods presented. Tier 1 leverage, Tier 1 capital and Risk-based capital ratios have regulatory minimum guidelines of 3%, 4% and 8% respectively, with requirements to be considered well capitalized of 5%, 6% and 10%, -18-

Other types of market risk, such as foreign currency exchange rate risk and commodity price risk, do not arise in the normal course of the Company's business activities. Interest rate risk is defined as an exposure to a movement in interest rates that could have an adverse effect on the Company's net interest income. Net interest income is susceptible to interest rate risk to the degree that interest-bearing liabilities mature or reprice on a different basis than earning assets. When interest-bearing liabilities mature or reprice more quickly than earning assets in a given period, a significant increase in market rates of interest could adversely affect net interest income. Similarly, when earning assets mature or reprice more quickly than interest-bearing liabilities, falling interest rates could result in a decrease in net interest income. -19-

In an attempt to manage its exposure to changes in interest rates, management monitors the Company's interest rate risk. Management's asset/liability committee (ALCO) meets monthly to review the Company's interest rate risk position and profitability, and to recommend strategies for consideration by the Board of Directors. Management also reviews loan and deposit pricing, and the Company's securities portfolio, formulates investment and funding strategies, and oversees the timing and implementation of transactions to assure attainment of the Board's objectives in the most effective manner. Notwithstanding the Company's interest rate risk management activities, the potential for changing interest rates is an uncertainty that can have an adverse effect on net income. In adjusting the Company's asset/liability position, the Board and management attempt to manage the Company's interest rate risk while enhancing the net interest margin. At times, depending on the level of general interest rates, the relationship between long and short term interest rates, market conditions and competitive factors, the Board and management may determine to increase the Company's interest rate risk position somewhat in order to increase its net interest margin. The Company's results of operations and net portfolio values remain vulnerable to changes in interest rates and to fluctuations in the difference between long and short-term interest rates. The primary tool utilized by ALCO to manage interest rate risk is a balance sheet/income statement simulation model (interest rate sensitivity analysis). Information such as principal balance, interest rate, maturity date, cash flows, next repricing date (if needed), and current rates is uploaded into the model to create an ending balance sheet. In addition, ALCO makes certain assumptions regarding prepayment speeds for loans and mortgage related investment securities along with any optionality within the deposits and borrowings. The model is first run under an assumption of a flat rate scenario (i.e. no change in current interest rates) with a static balance sheet over a 12-month period. A second and third model are run in which a gradual increase and decrease, respectively, of 200 basis points takes place over a 12 month period. A fourth and fifth model are run in which a gradual increase and decrease, respectively, of 100 basis points takes place over a 12 month period. Under these scenarios, assets subject to prepayments are adjusted to account for faster or slower prepayment assumptions. Any investment securities or borrowings that have callable options embedded into them are handled accordingly based on the interest rate scenario. The resultant changes in net interest income are then measured against the flat rate scenario. The following table summarizes the percentage change in net interest income in the rising and declining rate scenarios over a 12 month period from the forecasted net interest income in the flat rate scenario. In the declining rate scenarios, net interest income is projected to be below the flat rate scenario through the simulation period. Net interest income experiences a reduction as a result of adjustable rate loans repricing, and increased cash flow as a result of higher prepayments on loans reinvested at lower market rates, callable securities reinvested at lower market rates and limited continued deposit pricing reductions. In the plus 100 basis points scenario, net interest income is projected to be stable compared to the flat rate scenario. However, in the plus 200 basis point scenario net interest income is projected to remain at lower levels than in a flat rate scenario through the simulation period primarily due to a lag in assets repricing while funding costs increase. The potential impact on earnings is dependent on the ability to lag deposit repricing. Net interest income for the next twelve months in a +/- 200 basis point scenario is within the internal policy risk limits of a not more than a 5% change in net interest income. The following table projects the percent change in net interest income over the next year using the March 31, 2001 balance sheet position. -20-

TABLE 10 INTEREST RATE SENSITIVITY ANALYSIS ----------------------------------------------------------------------- Change in interest rates Percent change in (in basis points) net interest income ----------------------------------------------------------------------- +200 (1.39%) +100 0.12% -100 (0.96%) -200 (1.99%) ----------------------------------------------------------------------- LIQUIDITY RISK Liquidity management involves the ability to meet the cash flow requirements of customers who may be depositors wanting to withdraw funds or borrowers needing assurance that sufficient funds will be available to meet their credit needs. The ALCO is responsible for liquidity management and has developed guidelines which cover all assets and liabilities, as well as off balance sheet items that are potential sources or uses of liquidity. Liquidity policies must also provide the flexibility to implement appropriate strategies and tactical actions. Requirements change as loans grow, deposits and securities mature, and payments on borrowings are made. Liquidity management includes a focus on interest rate sensitivity management with a goal of avoiding widely fluctuating net interest margins through periods of changing economic conditions. The primary liquidity measurement the Company utilizes is called the Basic Surplus which captures the adequacy of its access to reliable sources of cash relative to the stability of its funding mix of average liabilities. This approach recognizes the importance of balancing levels of cash flow liquidity from short and long-term securities with the availability of dependable borrowing sources which can be accessed when necessary. Accordingly, the Company has purchased brokered time deposits, established borrowing facilities with other banks (Federal funds), the Federal Home Loan Banks of New York and Pittsburgh (short and long-term borrowings which are denoted as advances), and repurchase agreements with investment companies. This Basic Surplus approach enables the Company to adequately manage liquidity from both operational and contingency perspectives. By tempering the need for cash flow liquidity with reliable borrowing facilities, the Company is able to operate with a more fully invested and, therefore, higher interest income generating, securities portfolio. The makeup and term structure of the securities portfolio is, in part, impacted by the overall interest rate sensitivity of the balance sheet. Investment decisions and deposit pricing strategies are impacted by the liquidity position. At March 31, 2001, the Company considered its Basic Surplus adequate to meet liquidity needs. At March 31, 2001, a large percentage of the Company's loans and securities are pledged as collateral on borrowings. Therefore, future growth of earning assets will depend upon the Company's ability to obtain additional funding, through growth of core deposits and collateral management, and may require further use of brokered time deposits, or other higher cost borrowing arrangements. -21-
