Report of Independent Registered Public Accounting Firm

To the Compensation and Trust Committees
Hudson United Bancorp and Subsidiaries Savings and Investment Plan

We have audited the accompanying statements of net assets available for benefits of the the Hudson United Bancorp and Subsidiaries Savings and Investment Plan (the “Plan”) as of December 31, 2003 and 2002, and the related statements of changes in net assets available for benefits for the year ended December 31, 2003. 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.

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.

In our opinion, the financial statements referred to above present fairly, in all material respects, the Plan’s net assets available for benefits at December 31, 2003 and 2002, and the changes in its net assets available for benefits for the year ended December 31, 2003, in conformity with U.S. generally accepted accounting principles.

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 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 basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole.

1. Description of the Plan

The following description of the Hudson United Bancorp and Subsidiaries Savings and Investment Plan (the “Plan”) provides only general information. Participants should refer to the Plan Agreement and the Summary Plan Description for a more complete narrative of the Plan’s provisions.

General

The Plan is a defined contribution plan covering all employees of Hudson United Bancorp (the “Company”). Full-time employees are eligible to be admitted to the Plan upon completion of 1,000 hours of service in a six-month period (12 months for part-time employees) and the attainment of age 21. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).

Participant Accounts

Each participant’s account is credited with the participant’s contributions and allocations of (a) the Company’s contributions and (b) Plan earnings, and is charged with an allocation of administrative expenses. Allocations are based on participant account balances, as defined in the Plan Agreement. Forfeited balances of terminated participants’ non-vested accounts are used to reduce Company contributions. The benefit to which participant is entitled is the vested account balance.

Contributions

Each year, Plan participants may make pre-tax contribution to the Plan of 2% to 12% of their annual compensation. The Company makes matching pre-tax contributions of 50% of each employee’s contribution to a maximum of 3% of eligible annual compensation.

Upon enrollment, a participant may direct contributions in 10% increments to any of the Plan’s fund options. Participants may change their investment elections a maximum of three times per quarter. All employer matching contributions are allocated based on the participant’s election.

Participants aged 50 or older and who make the maximum allowable contribution to the Plan are entitled to contribute an additional catch-up contribution up to $2,000.

1. Description of the Plan (continued)

Vesting

All participants are immediately and fully vested in all participant contributions and the assets derived from their investment. Employees become fully vested in Company contributions and the assets derived from their investment in the event of any one of the following: attainment of age 65, upon retirement due to disability, death, plan termination, or the completion of five years of service with the Company. Employer contributions vest as follows:

Up to 2 years of service	=	0% vesting
After 2 years of service	=	25% vesting
After 3 years of service	=	50% vesting
After 4 years of service	=	75% vesting
After 5 years of service	=	100% vesting

Forfeitures of non-vested Company contributions for participants are used to reduce Company matching contributions to the Plan.

Participant Loans

Participants may borrow from their fund accounts up to 50% of their vested account balance. Loans are not issued to participants who have a loan outstanding under the Plan. Loan terms range from 1-5 years or up to 10 years for the purchase of a primary residence. The loans are secured by the balance in the participant’s account and bear interest at a rate established as the prevailing prime interest rate at the time of the loan issuance. Principal and interest is paid ratably through bi-weekly payroll deductions.

Payment of Benefits

Pursuant to a Plan provision, upon termination of employment, employees may receive a lump sum payment equal to the value of their account unless other method of payment has been selected as provided for by the Plan. Benefit payments are distributed to participants in the Employer Stock Fund in the form of the Company’s stock or cash, at the participant’s election.

Forfeited Accounts

At December 31, 2003, year to date forfeited non-vested accounts totaled $248,296, of which $215,000 was used to reduce 2003’s employer contributions. The remaining balance will be used to reduce future employer contributions.

2. Summary of Significant Account Policies

Basis of Accounting

The accounting records of the Plan are maintained on the accrual basis.

Investment Valuation and Income Recognition

Investments are stated at their aggregate fair value. Securities which are traded on a national securities exchange are valued at the last reported sales price on the last business day of the Plan year. The market value of the participation units in the Federated funds is based on quoted market value on the last business day of the Plan year.

The change in the difference between the fair value and cost of investments is reflected in the statement of changes in net assets available for benefits as net appreciation (depreciation) of investments, along with gains or losses realized on the sale of investments, which are determined using a specific identification basis.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.

Participant Loans

The participant loans are valued at their outstanding balances, which approximate fair value.

Payment of Benefits

Benefits are recorded when paid.

Operating Expenses

Trust administrative fees of the Plan are paid out of the Plan’s assets. All other plan expenses are paid for by the Company.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

3. Investments

The Plan’s investments are held by Reliance Trust Company.

The following table represents net realized gains and unrealized appreciation in fair value of investments for the year ended:

	December 31, 2003

At December 31, 2003 and 2002, the Plan held 471,661 and 552,736 shares of common stock, respectively, of the Company with a fair value of $17,427,870 and $17,190,081, respectively. Dividend income from this investment was $589,930 and $593,766 for the years ended December 31, 2003 and 2002, respectively. The Company provides Trust Administration services to the Plan. For the year ended December 31, 2003, the related fees paid to the Company amounted to $84,089.

The Plan’s record keeper is Federated Retirement Plan Services.

5. Income Tax Status

The Plan has received a determination letter from the Internal Revenue Service dated October 3, 2002, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the “Code”) and, therefore, the related trust is exempt from taxation. The Plan has been amended since receiving the determination letter. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan Administrator believes the Plan is being operated in compliance with the applicable requirement of the Code and, therefore, believes that the Plan is qualified and the related trust is tax exempt.

6. Plan Termination

Although the Company has not expressed any intent to do so, the Company has the right under the Plan to terminate the Plan subject to the provisions of ERISA.
