RETIREMENT SAVINGS PLAN We have audited the accompanying statements of net assets available for benefits of Healthcare Services Group, Inc. Retirement Savings Plan (the "Plan") as of December 31, 2005 and 2004, 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. 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. The Plan is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, 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 net assets available for benefits of the Plan as of December 31, 2005 and 2004, and the changes in net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at the end of year) as of December 31, 2005 is presented for the purpose of additional analysis and is not a required part of the basic 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 has been subjected to the auditing procedures applied in our audit of the basic 2005 financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2005 AND 2004 NOTE A.-DESCRIPTION OF PLAN The following description of the Healthcare Services Group, Inc. Retirement Savings Plan (the "Plan") provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. 1. General The Plan commenced October 1, 1999 and is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). The Plan is a defined contribution plan covering all non-highly compensated salaried employees who have one year of service (1,000 hours) and have attained the age of twenty-one or older with the exception employees whose employment is governed by a collective bargaining agreement. 2. Contributions Each year, participants may contribute up to 15% of their pretax annual compensation as defined in the Plan. There are no employer-matching contributions as defined in the Plan. A participant may elect to commence salary reductions as of the first day of the month coinciding with the date the employee satisfied the eligibility requirements. Participants may also rollover to the plan amounts representing distributions from other qualified defined benefit or defined contribution plans. Participants direct the investment of their contributions into various options offered by the Plan. Contributions are subject to certain limitations. 3. Participant Accounts Each participant's account is credited with the participant's contribution and allocations of Plan earnings. Allocations are determined by the participant. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. 4. Vesting Participants are vested immediately in their contributions plus actual earnings thereon. -5- HEALTHCARE SERVICES GROUP, INC. RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2005 AND 2004 NOTE A. (CONTINUED) 5. Administrative Expenses All administrative expenses were paid by the plan sponsor, Healthcare Services Group, Inc. 6. Benefit Payments On termination of service due to death or retirement, a participant may elect to receive either a lump-sum amount equal to the value of the participant's vested interest in his or her account or monthly, quarterly, semi-monthly or annual installments. No disability benefits, other than those payable upon termination of employment, are provided in the Plan. For termination of service for other reasons, a participant may receive the value of the vested interest in his or her account as a lump sum distribution. A Participant who has attained the age of 59 1/2 years may elect to receive a distribution of all or a portion of the vested amounts then credited to the Participant's account. The Participant will still continue to be eligible to participate in the Plan. A Participant may elect to receive an advance distribution for hardship under certain conditions as defined in the Plan and as subject to the evaluation of the Plan Administrator based on whether certain conditions have been satisfied. NOTE B.-SUMMARY OF ACCOUNTING POLICIES A summary of the significant accounting policies applied in the preparation of the accompanying financial statements follows: 1. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and changes therein, and disclosures of contingent assets and liabilities. Actual results could differ from those estimates. -6- HEALTHCARE SERVICES GROUP, INC. RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2005 AND 2004 NOTE B. (CONTINUED) 2. Investment Valuation and Income Recognition The Plan's investments are stated at fair value, which approximates market value, as reported to the Plan by PNC Bank. Quoted market prices are used to value investments. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. Purchases and sales of securities are recorded on a trade-date basis. 3. Benefit Payments Participants' withdrawals are recorded when paid. NOTE C.-INVESTMENTS The following presents investments that represent 5 percent or more of the Plan's net assets as of: December 31, --------------------- 2005 2004 ---------- -------- Fidelity Advisor Equity Growth Fund $ * $ 70,646 Fidelity Advisor Equity Income Fund 137,023 103,712 Growth Fund of America 119,469 * Janus Adviser Forty Fund 138,841 98,315 Janus Adviser Lg Cap Growth Fund 83,452 88,090 Healthcare Services Group, Inc. common stock 133,574 129,183 Black Rock Money Market Fund (PNC; Note E) 475,145 437,510 ---------- -------- $1,087,504 $927,456 ========== ======== * Balance did not represent at least 5% of Net Plan Assets During 2005 and 2004, the Plan's investments (including realized and unrealized gains and losses) appreciated in value by $96,536 and $85,561, respectively as follows: -7- HEALTHCARE SERVICES GROUP, INC.

NOTE E.-RELATED PARTY-IN-INTEREST TRANSACTIONS Certain Plan investments are shares of a money market fund managed by PNC Financial Services Group ("PNC"). PNC is the trustee as defined by the Plan and, therefore, these transactions qualify as party-in-interest transactions. In addition, certain plan investments are shares of the Healthcare Services Group, Inc. common stock. Healthcare Services Group, Inc. is the Plan sponsor as defined by the Plan and, therefore, these transactions qualify as party-in-interest transactions. The Plan held 6,449.7252 and 6,198.7968 shares of Healthcare Services Group, Inc. common stock with a quoted market value of $133,574 and $129,183 at December 31, 2005 and 2004, respectively. -8- HEALTHCARE SERVICES GROUP, INC. RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS (CONTINUED) DECEMBER 31, 2005 AND 2004 NOTE F.-TAX STATUS OF PLAN The Internal Revenue Service has determined and informed the Company by a letter dated March 7, 2001, that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code ("IRC"). The Plan has been amended since receiving the determination letter. However, an amendment required by IRS regulations has not been adopted as of December 31, 2005. The Plan has applied to the IRS under the Voluntary Correction Program to remedy this violation. Except for the violation noted above, the Plan administrator believes that the Plan is currently designed and being operated in compliance with the applicable requirements of the Internal Revenue Code. Therefore, no provision for income taxes has been included in the Plan's financial statements. NOTE G.-RISKS AND UNCERTAINTIES The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the statement of net assets available for benefits. -9- HEALTHCARE SERVICES GROUP, INC.
