<PAGE>

U.S.B HOLDING CO., INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.    Principles of Consolidation

      The consolidated financial statements include the accounts of U.S.B.
      Holding Co., Inc. (the "Company"), and its wholly-owned subsidiaries,
      Union State Bank (including its wholly-owned subsidiaries, U.S.B. Realty
      Corp., U.S.B. Financial Services, Inc., and Dutch Hill Realty Corp.) (the
      "Bank"), and the Company's non-bank subsidiaries, Ad Con, Inc. and Union
      State Capital Trust I.

2.    Reclassifications

      Certain reclassifications have been made to prior year accounts to conform
      to the current year's presentation.

3.    Basis of Presentation

      In the opinion of Management, the accompanying unaudited consolidated
      financial statements include all adjustments (comprising only normal
      recurring accruals) necessary to present fairly the financial position of
      the Company as of March 31, 1998, and operations and cash flows for the
      three month periods ended March 31, 1998 and 1997, and changes in
      stockholders' equity for the three month period ended March 31, 1998. A
      summary of the Company's significant accounting policies is set forth in
      Note 2 to the consolidated financial statements included in the Company's
      1997 Annual Report to Shareholders.

      The consolidated financial statements have been prepared in accordance
      with generally accepted accounting principles and predominant practices
      used within the banking industry. In preparing such financial statements,
      management is required to make estimates and assumptions that affect the
      reported amounts of assets and liabilities as of the dates of the
      consolidated statements of condition and the revenues and expenses for the
      periods reported. Actual results could differ significantly from those
      estimates.

      Estimates that are particularly susceptible to significant change relate
      to the determination of the allowance for loan losses and the valuation of
      other real estate acquired in connection with foreclosures or in
      satisfaction of loan receivables. In connection with the determination of
      the allowance for loan losses and other real estate owned, management
      obtains independent appraisals for significant properties.

4.    Forward-Looking Statements

      The Company has made, and may continue to make, various forward-looking
      statements with respect to earnings, credit quality and other financial
      and business matters for periods subsequent to March 31, 1998. The Company
      cautions that these forward-looking statements are subject to numerous
      assumptions, risks and uncertainties, and that statements relating to
      subsequent periods increasingly are subject to greater uncertainty because
      of the increased likelihood of changes in underlying factors and
      assumptions.

U.S.B HOLDING CO., INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)(Cont'd)

      Actual results could differ materially from forward-looking statements.

      In addition to those factors previously disclosed by the Company and those
      factors identified elsewhere herein, the following factors could cause
      actual results to differ materially from such forward-looking statements;
      competitive pressures on loan and deposit product pricing; other actions
      of competitors; changes in economic conditions; the extent and timing of
      actions of the Federal Reserve Board; customer deposit disintermediation;
      changes in customers' acceptance of the Company's products and services;
      and the extent and timing of legislative and regulatory actions and
      reform.

      The Company's forward-looking statements speak only as of the date on
      which such statements are made. By making any forward-looking statements,
      the Company assumes no duty to update them to reflect new, changing or
      unanticipated events or circumstances.

5.    Earnings Per Share

      On March 3, 1997, the Financial Accounting Standards Board ("FASB") issued
      Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings
      per Share." SFAS No. 128 is effective for financial statements issued for
      periods ending after December 15, 1997, including interim periods. The
      Company adopted SFAS No. 128 for the year ended December 31, 1997 and
      Earnings Per Share ("EPS") data is presented based on the requirements of
      this statement.

      SFAS No. 128 establishes standards for computing and presenting "Basic"
      and "Diluted" EPS. SFAS No. 128 states that Basic EPS excludes dilution
      and is computed by dividing net income available to common stockholders
      (net income after preferred stock dividend requirements) by the
      weighted-average number of common shares outstanding for the period.
      Diluted EPS 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 would then
      share in the earnings of the entity. Diluted EPS is computed similarly to
      "Fully Diluted EPS" pursuant to Accounting Principles Board ("APB")
      Opinion No. 15. Diluted EPS is based on net income available to common
      stockholders divided by the weighted average number of common shares
      outstanding and common equivalent shares ("adjusted weighted average
      shares"). Stock options granted but not yet exercised under the Company's
      stock option plans are considered common stock equivalents for Diluted EPS
      calculations.

6.    Reporting Comprehensive Income

      Effective January 1, 1998, the Company adopted SFAS No. 130, "Reporting
      Comprehensive Income," which establishes standards for reporting and
      display of comprehensive income and its components in a full set of
      general purpose financial statements. This statement requires that all
      items that are required to be recognized under accounting standards as
      components of comprehensive income be reported in a financial statement
      that is displayed with the same prominence as are the financial
      statements, except for interim financial reporting periods where
      disclosure is made in the notes to consolidated financial statements.
      Comprehensive income is defined as "the change in equity (net assets) of a
      business enterprise during a period from transactions and other events and
      circumstances from non-owner sources. It includes all changes in equity
      during a period, except those resulting from investments by owners and
      distributions to owners."

      These unrealized holding losses, net of tax benefit, represent a decrease
      in unrealized appreciation of available for sale securities, net of tax,
      during the three months ended March 31, 1998. The cumulative balance of
      this unrealized gain net of tax, at March 31, 1998 is $649,000.

7.    Disclosures About Segments of an Enterprise and Related Information

      In September 1997, the FASB issued SFAS No. 131 "Disclosures About
      Segments of an Enterprise and Related Information." This statement is
      effective for the Company's consolidated financial statements for the year
      ending December 31, 1998.

      SFAS No. 131 establishes standards for the way public business enterprises
      report information about operating segments in annual financial statements
      and requires that those enterprises report selected information about
      operating segments in subsequent interim financial reports issued to
      shareholders. It also establishes standards for related disclosure about
      products and services, geographic areas, and major customers. The
      statement requires that a public business enterprise report financial and
      descriptive information about its reportable operating segments. Operating
      segments are components of an enterprise about which separate financial
      information is available that is evaluated regularly by the chief
      operating decision maker in deciding how to allocate resources and assess
      performance. The statement requires that public business enterprises
      report a measure of segment profit or loss, certain specific revenue and
      expense items and segment assets. It also requires that information be
      reported about revenues derived from the enterprises' products or
      services, or about the countries in which the enterprises earn revenues
      and holds assets, and about major customers, regardless of whether that
      information is used in making operating decisions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)(Cont'd)

      This statement requires disclosures that the Company must make in its
      financial statements or notes thereto to the extent applicable.
      Accordingly, implementation of this statement will not have any effect on
      the Company's financial condition or results of operations. However,
      additional information will be provided to users of these financial
      statements as to the financial condition and operations of the Company.

8.    Loans

      Nonaccrual loans were $5.4 million at March 31, 1998 and $5.8 million at
      December 31, 1997. Restructured loans were $0.5 million and $0.6 million
      at March 31, 1998 and December 31, 1997, respectively.

      Substantially, all of the nonaccruing loans are collateralized by real
      estate, except for certain loans made by the Bank to Bennett Funding Group
      ("Bennett"), which are collateralized by cash and lease receivables. At
      March 31, 1998, the Company has no commitments to lend additional funds to
      any customers with nonaccrual or restructured loan balances.

      At March 31, 1998, there are loans aggregating approximately $100,000,
      which are not on nonaccrual status, that were potential problem loans
      which may result in their being placed on nonaccrual status in the future.

      At March 31, 1998 and December 31, 1997, the recorded investment in loans
      that are considered to be impaired under SFAS No. 114 "Accounting for
      Impairment of a Loan" approximated $4.6 million in each period ($4.2
      million in each period which were in nonaccrual status). Included in these
      loan balances are loans to Bennett. Each impaired loan has a related
      allowance for loan losses determined in accordance with SFAS No. 114. The
      total allowance for loan losses related to impaired loans was $1.8 million
      as of March 31, 1998 and December 31, 1997. The average recorded
      investment in impaired loans for the three months ended March 31, 1998 and
      year ended December 31, 1997 was approximately $4.6 million and $6.2
      million, respectively. For the three months ended March 31, 1998 and year
      ended December 31, 1997, interest income recognized by the Company on
      impaired loans was not material.

      Restructured loans in the amounts of $0.4 million at both March 31, 1998
      and December 31, 1997, that are considered to be impaired due to a
      reduction in the contractual interest rate are on accrual status because
      the collateral securing the loans is sufficient to protect the contractual
      principal and interest of the restructured loans. These loans have been
      performing for a reasonable period of time. Interest accrued on these
      loans not yet collected as of March 31, 1998 is immaterial.

U.S.B HOLDING CO., INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)(Cont'd)

      The Bank has approximately $3.3 million of outstanding loans,
      collateralized by cash and lease receivables, to Bennett, a lease finance
      company, which filed for bankruptcy protection during the first quarter of
      1996. Collection of the Bank's loans continues to be delayed by the
      bankruptcy proceedings. The Bank has not yet determined the extent of
      losses, if any, that will be sustained on these loans. However, based upon
      Bennett's filing, the loans have been placed on nonaccrual status and a
      specific reserve included in the allowance for loan losses of $1.6 million
      has been established in accordance with SFAS No. 114 as of March 31, 1998.

9.    Securities

      Securities that may be sold as part of the Company's asset/liability or
      liquidity management, or in response to or in anticipation of changes in
      interest rates and resulting prepayment risk, or for similar factors, are
      classified as available for sale and carried at fair value. Securities
      that the Company has the ability and positive intent to hold to maturity
      are classified as held to maturity and carried at amortized cost. Realized
      gains and losses on the sales of all securities, determined by using the
      specific identification method, are reported in earnings. Securities
      available for sale are shown in the Consolidated Statements of Condition
      at estimated fair value and the resulting net unrealized gains and losses,
      net of tax, are shown as a separate component of stockholders' equity.

      The decision to sell available for sale securities is based on
      management's assessment of changes in economic or financial market
      conditions, interest rate risk, and the Company's financial position and
      liquidity. Estimated fair values for securities are based on quoted market
      prices, where available. If quoted market prices are not available,
      estimated fair values are based on quoted market prices of comparable
      instruments. The Company does not acquire securities for the purpose of
      engaging in trading activities.

      At March 31, 1998, the effect of SFAS No. 115 resulted in an increase of
      securities available for sale of $1,125,000, representing the net
      unrealized gain, which, after the applicable tax effect, resulted in an
      increase to stockholders' equity of $649,000. At December 31, 1997, the
      effect of SFAS No. 115 resulted in an increase of securities available for
      sale of $2,250,000 which, after the applicable tax effect, resulted in an
      increase to stockholders' equity of $1,299,000.

10.   Borrowings and Stockholders' Equity

      The Company utilizes borrowings primarily to meet the funding requirements
      for its asset growth and to manage its interest rate risk. Borrowings
      include securities sold under agreements to repurchase, federal funds
      purchased, and Federal Home Loan Bank of New York ("FHLB") advances.

      The Bank may borrow up to $50.0 million from two primary investment firms
      under master security sale and repurchase agreements. At December 31,
      1997, the Bank had $34.9 million of such short-term borrowings outstanding
      with terms of between 21 and 31 days, at interest rates of between 5.86
      percent and 6.00 percent. The borrowings were collateralized by securities
      with an aggregate amortized cost and estimated fair value of $35.5 million
      and $35.6 million, respectively. There were no short-term borrowings under
      security sale and repurchase agreements at March 31, 1998.

      Federal funds purchased represent overnight funds. The Bank has federal
      funds purchase lines available with three financial institutions totaling
      $18.0 million. At March 31, 1998 and December 31, 1997, the Bank had no
      federal funds purchased balances outstanding.

      Short-term FHLB advances are borrowings with original maturities of
      between one and 365 days. At December 31, 1997, the Bank had short-term
      FHLB advances of $35.0 million outstanding with terms of 14 to 365 days,
      and at interest rates ranging from 5.63 percent to 6.13 percent. There
      were no short-term FHLB advances outstanding at March 31, 1998.

      Additional information with respect to short-term borrowings for the three
      months ended March 31, 1998 and 1997 is presented in the table below.

      At March 31, 1998 and December 31, 1997, long-term FHLB advances totaled
      $23.9 million and $24.2 million, respectively. At March 31, 1998,
      long-term FHLB advances aggregating $19.0 million are single principal
      payments and are not repayable prior to maturity without penalty.
      Long-term FHLB advances aggregating $4.9 million are amortizing advances
      having scheduled payments, but may not be repaid in full prior to maturity

      The Bank also has long-term borrowings of $59.8 million and $39.7 million
      in securities sold under agreements to repurchase as of March 31, 1998 and
      December 31, 1997, respectively. At March 31, 1998, these borrowings
      include $9.8 million having an original term of three years at an interest
      rate of 6.08 percent, and $50.0 million having an original term of between
      five and ten years at interest rates between 5.28 percent and 5.67 percent
      that are callable after an initial noncall period at the option of the
      counter party to the repurchase agreement. The borrowings are
      collateralized by securities with an aggregate amortized cost of $62.2
      million and estimated fair value of $62.9 million.

      At March 31, 1998 and December 31, 1997, the Bank has outstanding
      13,723,422 shares of capital stock in the FHLB with a carrying value of
      $13.7 million, which is required in order to borrow under the short and
      long-term advance and securities sold under agreements to repurchase
      programs from the FHLB. The FHLB generally limits borrowings up to an
      aggregate of 30 percent of total assets, excluding securities sold under
      agreements to repurchase, upon the prerequisite purchase of additional
      shares of FHLB stock. Any advances made from the FHLB are required to be
      collateralized by the FHLB stock purchased and certain other assets of the
      Bank.

      The dividend rate on the Company's Series "A" preferred stock issued to a
      single investor was determined quarterly and was subject to certain
      minimum and maximum per annum dividend rates as specified in the
      agreement. For the three month period ended March 31, 1997, the weighted
      average dividend rate was 8.4 percent (the minimum rate). Net income per
      common and common equivalent share reflects the preferred stock dividend
      declared and accrued totaling $34,000 for the three month period ended
      March 31, 1997. The Company redeemed the remaining outstanding amount of
      preferred stock of $3,250,000 on February 14, 1997.

      The Company issued a two-for-one stock split in the form of a 100% stock
      dividend on December 24, 1997. The weighted average shares outstanding and
      per share amounts for the three months ended March 31, 1997 have been
      adjusted to reflect the stock dividend distributed in 1997.

      The Company and the Bank's ability to pay cash dividends in the future are
      restricted by various regulatory requirements. The Company's ability to
      pay cash dividends to its shareholders is primarily dependent upon the
      receipt of dividends from the Bank. The Bank's dividends to the Company
      may not exceed the sum of the Bank's net income for that year and its
      undistributed net income for the preceding two years, less any required
      transfers to additional paid-in capital. At March 31, 1998, the Bank could
      pay dividends to the Company of $19.2 million without having to obtain
      prior regulatory approval.

11.   Commitments and Contingencies

      At March 31, 1998, the Company and Bank are committed under an employment
      agreement (as amended by action of the Company's and Bank's Boards of
      Directors on February 18, 1998), with a key officer, director and
      shareholder requiring annual salary and other payments of $530,000,
      increasing annually by $30,000 during the term of the contract, annual
      bonus payments equal to 6 percent of net income of the Company under the
      executive compensation plan, annual stock option grants of 96,800 shares,
      issued at fair value (110 percent of fair value for incentive stock
      options if the key officer's ownership of the Company equals or exceeds 10
      percent at the date of grant) and other benefits for the term of the
      contract expiring July 1, 1999.

      In the normal course of business, various commitments to extend credit are
      made which are not reflected in the accompanying consolidated financial
      statements. At March 31, 1998, formal credit line and loan commitments
      which are primarily loans collateralized by real estate and credit card
      lines approximated $161.7 million and outstanding letters of credit
      totaled $21.8 million. Such amounts represent the maximum risk of loss on
      these commitments.

      In connection with its asset and liability management program, the Bank
      entered into a protected rate agreement ("cap") which has a remaining
      aggregate notional amount of $2.5 million at March 31, 1998. The premium
      paid in the amount of $85,000 is deferred and is being amortized over the
      five year life of the cap which expires in 1999. Under the terms of the
      cap, the Bank will be reimbursed for increases in one-month LIBOR for any
      month during the term of the agreement in which such rate exceeds the
      "strike level" of 8.1875 percent. Interest rate cap agreements allow the
      Bank to limit its exposure to unfavorable interest rate fluctuations over
      and above the "capped" rate. The purchased cap hedges income payments from
      a mortgage-backed security with an interest rate adjusted annually to the
      one year Constant Maturity Treasury rate. The Bank has also entered into
      an interest rate swap contract, which effectively adjusts the short-term
      interest rate on a security sold under agreement to repurchase borrowing
      to a long-term fixed interest rate. Under the terms of the contract, the
      Bank is required to pay a fixed interest rate payment equal to 6.16
      percent of a notional amount of $10.0 million, and receive a payment equal
      to three-month LIBOR. The agreement expires on October 2, 1998. These
      agreements are subject to the counter party's ability to perform in
      accordance with the terms of the agreement. The Bank's risk of loss on the
      interest rate cap is equal to the unamortized premium paid to enter into
      this agreement, while the risk of loss on the interest rate swap is the
      fair value amount to be paid to terminate the contract, which was $31,000
      (liability) at March 31, 1998.

      The Bank enters into forward commitments to sell residential first
      mortgage loans to reduce market risk associated with originating and
      holding loans for sale. A risk associated with these commitments arises
      from the Bank's potential inability to generate loans to fulfill the
      contracts. To control the risk associated with changes in interest rates,
      the Bank may also use options to hedge loans closed and expected to close.
      No such contracts were outstanding at March 31, 1998.

      In the ordinary course of business, the Company is party to various legal
      proceedings, none of which, in the opinion of management, will have a
      material effect on the Company's consolidated financial position or
      results of operations.

12.   Acquisition of Tappan Zee Financial, Inc.

      On March 6, 1998, the Company and Tappan Zee Financial, Inc. ("Tappan
      Zee"), the parent company of Tarrytowns Bank, FSB, jointly announced that
      they have signed a definitive agreement pursuant to which they will enter
      into a business combination. The transaction is intended to be a tax free
      exchange of common shares and will be accounted for as a pooling of
      interests. Tappan Zee will be merged into the Company and Tarrytowns Bank,
      FSB will operate as a wholly-owned subsidiary of the Company.

      Under the terms of the agreement, each Tappan Zee shareholder will receive
      Company common stock that is anticipated to have a value of $22.00 per
      share for each Tappan Zee share. The exchange ratio will be finalized
      after all regulatory approvals are received. The minimum exchange ratio
      will be .88 Company shares for each Tappan Zee share if the Company's
      common stock has a value of $25.00 per share or higher, and, subject to
      the exception below, the maximum exchange ratio will be 1.24 Company
      shares for each Tappan Zee share if the Company's common stock has a value
      of $17.75 or lower. If the Company's common stock has a value of between
      $17.75 and $25.00 per share, the exchange ratio will be established to
      provide a value to Tappan Zee shareholders of $22.00 per share. If the
      Company's common stock falls below $15.00 per share, Tappan Zee will have
      the right to terminate the transaction subject to the Company's right to
      adjust the exchange ratio so as to assure that Tappan Zee shareholders
      receive a value of $18.60 per Tappan Zee share. Based on the Company's
      closing price per common share on March 6, 1998 and March 31, 1998 of
      $22.25 and $20.50 per share, each Tappan Zee share would be exchanged for
      0.99 and 1.07 shares, respectively, of Company common stock. The total
      value of the transaction is approximately $33.8 million, which represents
      1.51 time Tappan Zee's book value as of December 31, 1997.

      As of March 31, 1998, Tappan Zee has approximately $129 million in assets
      and operates a single banking facility in the Village of Tarrytown,
      Westchester County, New York. Had the business combination occurred as of
      March 31, 1998, the Company would have had approximately $1.160 billion in
      assets. After an acquisition charge of approximately $3 million to $3.5
      million (net of tax) in 1998, the transaction is expected to be accretive
      to earnings per share in 1999.

      The acquisition is contingent upon the satisfaction of necessary bank
      regulatory approvals, the approval of the shareholders of Tappan Zee and
      other customary conditions. The parties anticipate that the merger will be
      consummated in the third quarter of 1998.

      In connection with the merger agreement, Tappan Zee has granted the
      Company an option, exercisable under certain circumstances, to purchase
      294,134 shares, or 19.9%, of Tappan Zee's currently outstanding common
      stock.

13.   Subsequent Event

      On April 16, 1998, the Company announced that it intended to dissolve its
      Real Estate Investment Trust subsidiary, U.S.B. Realty Corp. (the "Realty
      Corp"), in a tax free liquidation. A proxy statement was mailed to the
      common and junior preferred shareholders of the Realty Corp. , and a
      special meeting was held on April 29th, at which time the shareholders of
      the Realty Corp. approved the proposal. The Company believes that
      dissolution of the Realty Corp. will make the Realty Corp. assets
      available for collateralization of Bank borrowings and will result in a
      reduction of the cost of administration. Dissolution of the Realty Corp.,
      subject to a number of conditions and factors, will also have a
      significant positive impact on the Company's 1998 tax provision, but may
      increase the effective tax rate slightly in future years.

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FINANCIAL CONDITION

At March 31, 1998, the Company had total assets of $1,031.3 million, an increase
of $7.9 million from December 31, 1997.

Total deposits increased $55.1 million for the three month period ended March
31, 1998 to $852.9 million, which represented a 6.9 percent increase from
December 31, 1997. Time deposits increased $26.2 million accounting for the
greatest component of deposit increases. Retail time deposits under $100,000
increased by $4.5 million due primarily to time deposit promotions, and other
time deposits over $100,000 increased by $1.5 million during the three month
period ended March 31, 1998. Time deposits greater than $100,000 from local
municipalities, which are obtained on a bidding basis with maturities of 30 to
180 days, increased by $20.5 million as part of the Bank's overall leveraging
strategy. IRA and Keogh time deposit accounts decreased by $0.2 million due to
significant competition for this product. Savings deposits increased by $17.1
million, as the Company's "Golden Statement" and "Liquid Gold" accounts, which
provide attractive yields for high balance accounts, continued to attract
additional deposits. NOW accounts and demand deposits increased by $11.4 million
and $1.5 million, respectively. Money market deposits decreased by $1.1 million,
as customers generally switched money market account balances to higher yielding
deposit products.

The securities portfolio, including investment in FHLB stock, of $383.5 million
and $394.6 million at March 31, 1998 and December 31, 1997, respectively,
consists of securities held to maturity at amortized cost of $70.8 million and
$137.2 million, securities available for sale at estimated fair value totaling
$299.0 million and $243.7 million, respectively, and FHLB stock of $13.7 million
in each period.

During the three months ended March 31, 1998, U.S. Treasury and government
agency obligations decreased $84.0 million due primarily to sales and
redemptions of securities totaling $104.5 million and a net decrease in the
market value of available for sale securities of $0.5 million, partially offset
by purchases of $1.0 million in U.S. Treasury Notes, $20.0 million in callable
bonds. Mortgage-backed securities increased by $74.4 million primarily due to
purchases of $112.9 million, which were offset by a net decrease in the market
value of available for sale securities of $0.6 million, sales and redemptions
totaling $31.1 million and principal amortizations of $6.8 million.
Mortgage-backed security purchases are fixed-rate securities having expected
weighted-average lives of less than ten years. The mortgage-backed securities
sold have low yields or expectations to prepay in the near-term and were also
sold to take advantage of favorable market conditions. The Company's investment
in obligations of states and political subdivisions, or municipal securities,
decreased by $1.4 million due to maturities during the first three months of
1998. Municipal securities are considered core investments which are high
yielding on a tax equivalent basis and have diversified maturities. Purchases of
municipal securities are dependent upon their availability in the marketplace
and the comparative tax equivalent yield of such securities to other securities
of comparable credit risk and maturity. The Company currently has no outstanding
holdings in corporate bonds as all such bonds aggregating $0.9 million matured
during the quarter ended March 31, 1997. Medium-term corporate debt securities
which are rated investment grade by nationally recognized credit rating
organizations will continue to be evaluated for investment in the future.

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS(Cont'd)

FINANCIAL CONDITION (Cont'd)

The Company continues to exercise its conservative approach to investing by
making high quality investments and controlling interest rate risk by purchasing
both fixed and floating rate securities and through the averaging of investments
in medium-term maturities.

At March 31, 1998, loans were $588.3 million, a net increase of $24.7 million or
4.4 percent over December 31, 1997. The primary increases of outstanding loan
balances were $12.5 million in time secured loans, $10.7 million in land
acquisition and construction loans, and $3.8 million in residential mortgages
and home equity loans, offset by a net reduction of $2.3 million in all other
loan categories. The Bank had approximately $161.7 million in formal credit
lines and loan commitments outstanding. Management considers its liquid
resources to be adequate to fund loans in the foreseeable future, principally by
utilizing excess funds temporarily placed in federal funds sold, increases in
deposits and borrowings, loan repayments and maturing securities.

The Bank has approximately $3.3 million of loans, collateralized by cash and
lease receivables, to Bennett Funding Group ("Bennett"), a lease finance
company, which filed for bankruptcy protection during the first quarter of 1996.
Collection of these loans continue to be delayed by the bankruptcy proceedings.
The Bank has not yet determined the extent of losses, if any, that will be
sustained on these loans. However, based upon Bennett's filing, the loans have
been placed on nonaccrual status. Including the Bennett loans, the Bank's
nonaccrual loans and other real estate owned were 0.70 percent of total assets
at March 31, 1998.

The Bank's allowance for loan losses increased $0.3 million or 3.6 percent to
$7.8 million at March 31, 1998, from $7.6 million at December 31, 1997. The
allowance for loan losses represents 1.33 percent of gross loans outstanding at
March 31, 1998, compared to 1.34 percent at December 31, 1997. The allowance
reflects a provision of $300,000 and net charge-offs of $25,000 recorded thus
far in 1998. Management takes a prudent and cautious position in evaluating
various business and economic uncertainties in relation to the Bank's loan
portfolio. In management's judgment, the allowance is considered adequate to
absorb potential losses inherent in the loan portfolio.

During the three months ended March 31, 1998, the Bank decreased the amount of
outstanding short- and long-term advances with the Federal Home Loan Bank of New
York by $35.3 million, while borrowings under repurchase agreements decreased by
$14.9 million. Borrowings decreased, as such funding was replaced by retail
deposits and municipal deposits on a bid basis at a lower cost. As noted above,
municipal time deposits increased $20.5 million.

Stockholders' equity increased to $64.6 million at March 31, 1998 from the
December 31, 1997 balance of $62.6 million. The increase primarily results from
net income of $3.0 million for the three month period ended March 31, 1998, and
a decrease in shares held in trust for deferred compensation of $0.3 million,
partially offset by a decrease in the net unrealized gain on securities
available for sale, net of tax of $0.7 million and dividends paid. During the
first three months of 1998, the Company also purchased 909 shares of treasury
stock at market value for $19,000.

FINANCIAL CONDITION (Cont'd)

The Company's leverage ratio at March 31, 1998 was 8.22 percent, compared to
8.26 percent at December 31, 1997. The Company's Tier I and total capital ratios
under the risk-based capital guidelines were 13.03 percent and 14.24 percent at
March 31, 1998 and 12.63 percent and 13.80 percent at December 31, 1997,
respectively. In addition, the Bank exceeds all current regulatory capital
requirements and was in the "well-capitalized" category at March 31, 1998 and
December 31, 1997.

RESULTS OF OPERATIONS

Earnings

Net income for the three month period ended March 31, 1998 increased $619,000 or
26.5 percent to $2,951,000 compared to the same period in 1997. Basic and
diluted earning per share increased to $0.24 and $0.22, respectively, from $0.19
and $0.17 in the same periods in 1997, respectively. The annualized return on
average total assets was 1.16 percent for the three month period ended March 31,
1998, compared to 1.11 percent for the three month period ended March 31, 1997.
The annualized return on average common equity was 18.50 percent for the three
months ended March 31, 1998 compared to 17.13 percent for the comparative period
in 1997. The overall increase in earnings in the 1998 period primarily reflects
higher net interest income resulting from increased volume and effective
leveraging of the balance sheet, higher security gains, service charges and fees
and a lower provision for loan losses, offset by higher non-interest expenses to
support increased business and lower other income. A discussion of the factors
impacting the changes in the various components of net income follows.

Net Interest Income

Net interest income, the difference between interest income and interest
expense, is a significant component of the Company's consolidated earnings. For
the three month period ended March 31, 1998, net interest income increased 12.6
percent to $9.0 million from $8.0 million in the year earlier period. Net
interest income increased in the current year period due to volume increases of
average earning assets, partially offset by a decrease in the net interest
spread. For the three months ended March 31, 1998, the interest spread (yield on
earning assets less cost of interest-bearing funds) was 3.05 percent compared to
3.36 percent in the same period of 1997. Yields on interest earning assets
decreased during the three month period ended March 31, 1998, while the cost of
funds increased compared to the same period in 1997, resulting in the negative
impact on the net interest spread. The decrease in asset yields is partially as
a result of lower yields available on security investments and redemptions of
callable agency securities at higher yields, as well as declining yields on
loans due to increased competition and a general decline in intermediate term
interest rates. The cost of funds increased due to the leverage strategy
discussed below and growth of deposits in higher rate instruments, while deposit
costs generally remained stable due to the flat yield curve and tendency of
customers to favor short-term deposit products. The decrease in the spread is
also affected by the Company's leverage strategy of purchasing government
securities funded by borrowings and/or municipal deposits at tighter spreads.
Although leverage strategies

result in decreasing interest spreads, they have the effect of increasing net
interest income while managing interest rate risk.

Provision for Loan Losses

The provision for loan losses decreased $330,000 to $300,000 for the three month
period ended March 31, 1998, compared to the same period in 1997. Net
charge-offs in the three month period ended March 31, 1998 totaled $25,000
relating primarily to credit card loans, compared to net charge-offs
(principally real estate loans) of $107,000 for the three month period ended
March 31, 1997. Nonaccrual loans were $5.4 million and $7.7 million,
respectively, at March 31, 1998 and 1997, compared to $5.8 million at December
31, 1997. The Bank has approximately $3.3 million of loans, collateralized by
cash and lease receivables, to Bennett, a lease finance company, which filed for
bankruptcy during the first quarter of 1996. The Bank does not yet know the
extent of losses, if any, that will be sustained on these loans. However, based
upon Bennett's filing, the loans were placed on nonaccrual status in March 1996.
It is the Company's policy to discontinue the accrual of interest on loans when,
in the opinion of management, a reasonable doubt exists as to the timely
collectibility of the amounts due. Net income is adversely impacted by the level
of non-performing assets of the Company since, in addition to foregone revenue,
the Company must increase the level of provision for loan losses, and incur
other costs associated with collections of past due balances.

An evaluation of the quality of the loan portfolio is performed by management on
an ongoing basis as an integral part of the loan function, which includes the
identification of past due loans, the recognition of the current economic
environment and the review of the historical loan experience. Management has
taken a prudent and cautious position in evaluating various business and
economic uncertainties in relation to the Company's loan portfolio and believes
that the allowance for loan losses at March 31, 1998 reflects the risk elements
inherent in the total loan portfolio at this time. The changes in the provision
charged to income and the allowance for loan losses reflects such uncertainties
on an increasing loan portfolio. There is no assurance that the Company will not
be required to make future adjustments to the allowance in response to changing
economic conditions or regulatory examinations.

Non-Interest Income

Non-interest income for the three months ended March 31, 1998 increased by
$334,000 to $1,192,000, compared to the same period of 1997. The increase is
primarily related to higher net gains on securities and loan transactions
($314,000) and other income ($47,000), partially offset by lower service charges
and fees ($27,000). Other income consists of ATM fees, credit card fees, loan
servicing income, wire transfer fees, safe deposit, and other fees.

Non-Interest Expenses

Non-interest expenses increased $810,000 to $5,709,000 for the three month
period ended March 31, 1998, from the comparable period in 1997. The primary
reason for this increase results from an increase in the cost of salaries and
other operating costs to support the growth of the Bank. The following discusses
each component of non-interest expense.

Salaries and benefits, the largest component of non-interest expense, increased
by $457,000, or 17.1 percent, during the three month period ended March 31, 1998
compared to the previous year period. The increase occurred due to additional
personnel employed by the Bank to accommodate the increases in deposits and
loans and their related services, and increases in business development efforts,
and annual merit increases. In addition, employee benefits increased because of
higher incentive compensation programs which are based upon the Company's net
income and overall financial performance, higher payroll taxes during 1998 due
to the higher salary base and increases in the cost of other employee benefit
programs such as medical coverage, tuition reimbursement, and training.

The changes in the other components of non-interest expenses for the three month
period ended March 31, 1998 compared to March 31, 1997, were due to the
following:

o     Increase of $171,000 (18.1%) in occupancy and equipment expense. This
      increase is due principally to higher maintenance expenses relating to the
      Bank's branch and computer related equipment due to increased business
      volume, and additional rental and depreciation expense associated with two
      new branch openings.

o     Increase of $87,000 (45.8%) in advertising and business development. The
      increase reflects increased emphasis on marketing, and the introduction of
      the Bank's new ad campaign, "Do business with us, do better with us," as
      well as advertising and business development expense for the new branches.

o     Decrease of $72,000 (20.3%) in professional fees. The decrease relates to
      lower professional fees primarily associated with loan collections,
      foreclosures and other litigation.

o     Increase of $8,000 (4.1%) in communications is due to an increase in
      postage and telephone expenses that arose as a result of higher postal
      volume related to the growth in business.

o     Increase of $43,000 (36.4%) in stationery and printing. The increase
      occurred due to printing costs and supplies necessitated by increased loan
      and deposit volume and opening of Suffern and New Rochelle branches.

o     Increase of $4,000 in FDIC insurance premiums results from higher deposit
      balances.

o     Increase of $112,000 (27.2%) in other expenses, results from higher
      foreclosure related expenses and other costs to support increased volume,
      higher branch charge-offs, and accruals for a contribution to the U.S.B
      Foundation, Inc., as well as higher costs associated with stockholder
      relations and stock exchange fees.

Income Taxes

The effective tax rates for the three month period ended March 31, 1998 and 1997
was 29.9 and 30.3, percent, respectively. The decrease in the overall effective
tax rate in 1998 primarily reflects lower state income taxes.

Year 2000 Issue

The Company continues to monitor the Year 2000 issue as more fully described in
the Company's 1997 Annual Report and Form 10-K. The Company has identified all
systems that are Year 2000 compliant and received confirmation from software
vendors of such compliance. The Company's major core system software vendor has
certified that its software is Year 2000 compliant. For systems not yet
compliant, software vendors are in the process of providing updates to ensure
such systems are compliant. In addition, significant customers are being
contacted to determine their progress toward Year 2000 compliance to evaluate
the potential impact on the Company from their failure to remediate their Year
2000 issues.

The Company's Year 2000 Committee reports progress to the Company's and Bank's
Board of Directors on a quarterly basis. The Company expects to have identified
and tested all significant Year 2000 sensitive systems by December 31, 1998.
However, there can be no guarantee that the systems of other entities on which
the Bank's systems rely will be timely converted, or that a failure to convert
by another entity, or a conversion that is incompatible with the Company's
systems, would not have a material adverse effect on the Company.

The Company's Year 2000 project cost to date and estimates to complete are not
expected to be significant. Such costs are being expensed as incurred. The cost
of the project and the date on which the Company plans to complete the Year 2000
modifications are based on management's best estimates, which were derived
utilizing numerous assumptions of future events including the availability of
certain resources, third party modification plans and other factors. However,
there can be no guarantee that these estimates will be achieved and actual
results could differ materially from those plans.

The Company will continue to evaluate all issues with respect to the Year 2000
problem to minimize the impact on its operations and financial condition.

U.S.B. HOLDING CO., INC.
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Quantitative and qualitative disclosures on market risk at December 31, 1997
were previously reported in the Company's 1997 Annual Report and Form 10-K.
There have been no material changes in the Company's market risk exposures at
March 31, 1998 compared to December 31, 1997. Interest rate risk continues to be
the Company's primary market risk exposure since all Company transactions are
denominated in U.S. dollars with no direct foreign currency exchange or changes
in commodity price exposures. All market risk sensitive instruments continue to
be held to maturity or available for sale with no financial instruments entered
into for trading purposes. The Company does not use derivative financial
instruments such as interest rate swaps and caps extensively. However, as
disclosed in the Company's 1997 Annual Report and Form 10-K, two interest rate
contracts are in place to manage the Company's interest rate exposure. The
Company has not entered into any new derivative financial instruments during the
three months ended March 31, 1998.

The Company continues to use two methods to evaluate its market risk to changes
in interest rates. A "Static Gap" evaluation and a simulation analysis of the
impact of changes in interest rates on the Company's net interest income and
cash flow. There have been no changes in the Company's policy limit of
acceptable variances to net interest income at March 31, 1998 as compared to
December 31, 1997. The changes in the composition of the Company's assets and
liabilities for the three months ended March 31, 1998 as reported in the
Management's Discussion and Analysis of Financial Condition and Results of
Operations have not materially affected the Company's overall interest rate risk
profile at March 31, 1998 as compared to December 31, 1997. The Company's
"static gap" at March 31, 1998 has not changed materially from December 31,
1997. If interest rates were to gradually ramp up or down 200 basis points from
current rates, the percentage change in estimated net interest income for the
subsequent 12 month measurement period continues to be within the Company's
policy limit of not declining by more than 5.0%.
