FORWARD LOOKING STATEMENTS/RISK FACTORS
Certain matters discussed may 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 the Company providing its
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 revenues in 2004; 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 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
Prospective Payment System. That change, and 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 Earnings Release Page 3 of 6
February 15, 2005 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.
