<P>Retirement and Thrift Plan Committee</P>
<P>S&amp;T Bank</P>
<P ALIGN="JUSTIFY">We have audited the accompanying statements of net assets available for benefits of the Thrift Plan for Employees of S&amp;T Bank as of December&nbsp;31, 2003 and 2002, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits.</P>
<P ALIGN="JUSTIFY">We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. </P>
<P ALIGN="JUSTIFY">In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December&nbsp;31, 2003 and 2002, and the changes in its net assets available for benefits for the years then ended, in conformity with U.S. generally accepted accounting principles.</P>
<P ALIGN="JUSTIFY">Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December&nbsp;31, 2003 is presented for purposes of additional analysis and is not a required part of the financial statements, but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole.</P>

<P>1. Summary of Significant Accounting Policies</P>
</B><P ALIGN="JUSTIFY">A description of significant accounting policies of the Thrift Plan for Employees of S&amp;T Bank (the Plan) is presented below.</P>
<B><P>General</P>
</B><P ALIGN="JUSTIFY">The financial statements have been prepared on the accrual basis of accounting.</P>

</B><P ALIGN="JUSTIFY">The investment assets are held in trust with the Wealth Management Group of S&amp;T Bank (the Trustee). </P>
<B><P>Valuation of Investments</P>
</B><P ALIGN="JUSTIFY">Investments are stated at estimated fair value. Securities traded on a national securities exchange are valued at the last reported sales price on the last business day of the plan year; investments traded in the over-the-counter market and listed securities for which no sale was reported on that date are valued at the average of the last reported bid and asked prices. Short-term investment funds and mutual funds are valued based on quoted market prices as of the end of the plan year. </P>
<B><P>Realized Gains and Losses</P>
</B><P ALIGN="JUSTIFY">Realized gains and losses from investment transactions are computed using the specific identification method.</P>
<B><P>Use of Estimates</P>
</B><P ALIGN="JUSTIFY">The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.</P>
<B><P>2. Description of the Plan</P>
</B><P ALIGN="JUSTIFY">The Plan was adopted effective May&nbsp;1, 1984 and made retroactive to January&nbsp;1, 1984 by S&amp;T Bank (Plan Sponsor and Employer).</P>

</B><P ALIGN="JUSTIFY">The Plan is a vehicle for accepting employee and Employer tax-deferred contributions and employee after-tax contributions. Eligible employees (participants) determine the amount of their deferred cash contributions to the Plan. Employer matching contributions are equal to 50% of the employee contributions, not to exceed 3% of compensation. Employer discretionary contributions are determined by the Board of Directors of the Plan Sponsor.</P>
<P ALIGN="JUSTIFY">The Plan was amended, effective December&nbsp;30, 1988, to include an Employee Stock Ownership Plan (ESOP). The ESOP covers substantially all regular employees under the Plan. ESOP contributions were invested primarily in qualified securities (common stock) of S&amp;T Bancorp, Inc. (Bancorp), the parent company of the Plan Sponsor. At December&nbsp;31, 2003 and 2002, there were no unreleased shares from the Plan. </P>
<P ALIGN="JUSTIFY">Individual accounts are maintained for each participant. Participants may elect to invest their contributions in one or more of various investment options. Employer matching contributions are invested in the same proportions. The Employer discretionary contributions are made at the direction of the Retirement and Thrift Plan Committee of the Plan Sponsor. Participants are permitted to transfer all balances in their accounts among investment options.</P>
<P ALIGN="JUSTIFY">Each participant's account is credited with the participant's contributions, Employer matching contributions and allocations of other Employer contributions and fund earnings, which are allocated based on the participant's compensation and the participant's fund balances, respectively. The benefit to which a participant is entitled is the amount aggregated in the participant's account. </P>
<P ALIGN="JUSTIFY">Participants are immediately vested in all amounts credited to their accounts. On termination of service, participants may elect either to receive a lump-sum distribution from their accounts, or to leave their funds in the Plan, provided their balance is at least $5,000.</P>
<P ALIGN="JUSTIFY">At December&nbsp;31, 2003 and 2002, benefit payments in the amount of $105,915 and $49,837, respectively, were owed to participants who had elected to withdraw from the Plan, but had not yet been paid.</P>
<P ALIGN="JUSTIFY">The Plan Sponsor reserves the right to amend or discontinue the Plan. In the event of a termination of the Plan, plan assets would be used for the benefit of participants and their beneficiaries, as prescribed by law.</P>
