Net income increased 33% for the three months ended September 30, 2004 to

         Revenues for the nine months ended September 30, 2004 increased by over

close of business October 29, 2004. This represents a 14% increase over the
dividend declared for the 2004 second quarter and is the sixth consecutive
quarterly dividend payment, as well as the fifth consecutive increase since the

FORWARD LOOKING STATEMENTS/RISK FACTORS

Certain matters discussed include 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 20% of 2004 nine month period revenues; our claims' experience
related to workers' compensation and general liability insurance; the effects of
changes in laws and regulations governing the industry and risk factors
described in our Form 10-K filed with the Securities and Exchange Commission for
the year ended December 31, 2003 in Part I thereof under "Government Regulation
of Clients", "Competition" and "Service Agreements/Collections". 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 the 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 our 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 the various operational levels of the Company. Furthermore, we believe that
its 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.
