 Safe Harbor Statements under the Private Securities Litigation Reform Act of 1995.
 The foregoing statements regarding prospects for future earnings and revenues, future
sales trends and the introduction of products under development are forward-looking statements that
involve certain risks and uncertainties. A number of important factors could cause actual results
to differ materially from those contemplated by such forward-looking statements. These include the
potential loss of one of our major customers upon whom we depend for a material portion of our
business, increased competition and continuing downward pressure on prices for certain of our
products, the potential introduction of new products with perceived competitive advantages over the
Companys products, changes or proposed changes in health care reimbursement which affect home care
providers, the terms of any distribution agreement which may be negotiated with respect to our
TOTAL O2 system or our sleep products, and CHADs ability to anticipate and respond to
technological and economic changes in the home oxygen market. Moreover, the success of the
Companys products and products under development will depend on their efficacy, reliability and
the health care communitys perception of the products capabilities and benefits, the degree of
acceptance the products achieve among homecare providers and, with respect to products under
development, obtaining timely regulatory approval. Additional factors that could cause actual
results to differ materially from those contemplated in this press release can be found in the
Companys annual and quarterly reports filed with the Securities and Exchange Commission under the
caption Outlook: Issues and Risks.
