FORWARD LOOKING STATEMENTS/RISK FACTORS

This report includes forward-looking statements that are subject to risks and
uncertainties that could cause actual results or objectives to differ materially
from those projected. We undertake no obligation to publicly update or revise
any forward-looking statements, whether as a result of new information, future
events or otherwise. Such risks and uncertainties include, but are not limited
to, risks arising from our providing services exclusively to the health care
industry, primarily providers of long-term care; credit and collection risks
associated with this industry; one client accounting for approximately 19% of
2006 six month period revenues ( the client has completed its previously
announced merger on March 14, 2006); our claims' experience related to workers'
compensation and general liability insurance; the effects of changes in, or
interpretations of laws and regulations governing the industry, including state
and local regulations pertaining to the taxability of our services; and risk
factors described in our Form 10-K filed with the Securities and Exchange
Commission for the year ended December 31, 2005 in Part I thereof under
"Government Regulation of Clients", "Competition" and "Service
Agreements/Collections" and "Risk Factors". Many of our clients' revenues are
highly contingent on Medicare and Medicaid reimbursement funding rates, which
have been and continue to be adversely affected by the change in Medicare
payments under the 1997 enactment of Medicare Prospective Payment System. That
change, and the lack of substantive reimbursement funding rate reform
legislation, as well as other trends in the long-term care industry have
resulted in certain of our clients filing for bankruptcy protection. Others may
follow. Any decisions by the government to discontinue or adversely modify
legislation related to reimbursement funding rates will have a material adverse
affect on our clients. These factors, in addition to delays in payments from
clients, have resulted in and could continue to result in significant

additional bad debts in the near future. Additionally, our operating results
would also be adversely affected if unexpected increases in the costs of labor
and labor related costs, materials, supplies and equipment used in performing
our services could not be passed on to clients.

         In addition, we believe that to improve our financial performance we
must continue to obtain service agreements with new clients, provide new
services to existing clients, achieve modest price increases on current service
agreements with existing clients and maintain internal cost reduction strategies
at our various operational levels. Furthermore, we believe that our ability to
sustain the internal development of managerial personnel is an important factor
impacting future operating results and successfully executing projected growth
strategies.

         Healthcare Services Group, Inc. is the largest national provider of
professional housekeeping, laundry and food services to long-term care and
related facilities.
