                       Institutional Shareholder Services
                    Recommends CHAD Therapeutics Shareholders
                    Vote For Management's Slate of Directors

      CHATSWORTH, California, September 3, 2003 . . . CHAD Therapeutics, Inc.
(ASE:CTU) announced today that Institutional Shareholder Services (ISS), the
nation's leading independent stockholder advisory organization, has recommended
a vote in favor of CHAD's nominees to the Board of Directors at the 2003 Annual
Meeting of Shareholders to be held on September 9, 2003.

      ISS cited many of the arguments the Company raised in its letters to
shareholders in support of its decision to recommend a vote in favor of CHAD's
nominees and not the dissident shareholder who has been waging a proxy contest
in an attempt to elect himself to CHAD's Board of Directors.

      Thomas E. Jones, CHAD's Chief Executive Officer, said, "We are pleased to
have the recommendation of ISS based on its independent review. We also are
thankful for the many expressions of support we have received from individual
shareholders who recognize the success of our turnaround plan. We strongly
believe that the best way to enhance value for CHAD shareholders is to build a
solid company with quality products that meet the needs of our customers and
their home oxygen patients. We have introduced a number of new products over the
past three years that have been the foundation of our turnaround, and we have
entered into new technology agreements this year that expand our efforts in this
area. We urge our shareholders to support CHAD's nominees on the WHITE proxy
card."

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 loss of
one or more major customers, increased competition, the 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 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

Exchange Commission under the caption "Outlook: Issues and Risks."
