FORWARD LOOKING STATEMENTS/RISK FACTORS

This earnings release 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 revenues in 2005 (such client's Board of Directors have
reached terms for a sale of its company, which sale could be completed in the
first quarter of 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 most recent Form 10-K filed with the Securities and Exchange
Commission for the year ended December 31, 2004 and in Part I thereof under
"Government Regulation of Clients", "Competition" and "Service
Agreements/Collections". Many of our clients' revenues are highly reliant 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 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 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 further improve our future 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.

professional housekeeping, laundry and food services to long-term care and
