CAUTIONARY STATEMENT REGARDING FORWARD LOOKING STATEMENTS
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
revenues in the three month period ended March 31, 2006 (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 the 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", "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 be
adversely affected if unexpected increases in the costs of labor and labor
related costs, materials, supplies and equipment used in performing 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.
