1.   Interim Reporting

Chad Therapeutics, Inc. (the Company) is in the business of developing,
producing and marketing respiratory care devices designed to improve the
efficiency of oxygen delivery systems for home health care and hospital
treatment of patients suffering from pulmonary diseases.

In the opinion of management, all adjustments necessary, which are of a normal
and recurring nature, to a fair statement of the results for the interim periods
presented have been made. The interim statements are condensed and do not
include some of the information necessary for a more complete understanding of
the financial data. Accordingly, your attention is directed to the footnote
disclosures found on pages 12, 13 and 14 of the March 31, 1995, Annual Report
and particularly to Note 1 which includes a summary of significant accounting
policies.

2.  Inventories

    Inventories at December 31, 1995, are summarized as follows:

3.  Net Earnings Per Common Share

Net earnings per common share is based on the weighted average number of shares
and common stock equivalents (stock options) outstanding. The weighted average
number of shares for the periods ended December 31, 1995, has been restated for
the 3 for 2 stock split paid on October 16, 1995.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

                                December 31, 1995

Results of Operations

Sales for the three and nine months ended December 31, 1995, increased $974,000
and $4,473,000 or 26.6% and 41.8%, respectively, over the prior year's periods.
There were no price increases during the period presented. The increase in sales
relates primarily to increases in domestic sales of OXYMATIC conservers and
OXYLITE complete portable oxygen systems which are benefiting from the current
marketing environment for home oxygen therapy discussed below.

Sales to foreign distributors represented 13.8% and 13.1% of total sales for the
periods ended December 31, 1995 and 1994, respectively, as these sales increased
at a slightly slower rate than domestic sales. Currently, management expects
sales to foreign distributors during the upcoming fiscal year to increase on an
annual basis; however, quarter to quarter sales will fluctuate depending on the
timing of shipments. In addition, all foreign sales are transacted in dollars,
thus quarter to quarter unit sales could be affected by foreign currency
fluctuations.

In June, 1989, a new procedure for payment by Medicare for home oxygen services
became effective which provides a prospective flat fee monthly payment based
solely on the patient's prescribed oxygen requirement. Previously dealers were
reimbursed on the basis of total oxygen delivered and a rental charge which
varied based on the type of system being used and other factors. The prior
procedure tended to encourage waste and inefficiency. Consequently, with the
incentive now to operate efficiently, inexpensive concentra tors have grown in
popularity because of low cost and less frequent servicing requirements. At the
same time, interest heightened in oxygen conserving devices which can extend the
life of oxygen supplies and reduce service calls by dealers. Management believes
the new reimbursement procedures have heightened interest in the cost savings
and increased mobility afforded by oxygen conserving devices such as the
Company's products.

In addition, other changes in the health care delivery system - including the
increase in the acceptance and utilization of managed care - has stimulated a
significant consolidation among home oxygen dealers. As major national and
regional home medical equipment chains attempt to secure managed care contracts
and improve their market position, they have expanded their distribution
networks through the acquisition of independent dealers in strategic areas. The
Company's products, which allow homecare dealers to provide cost efficient home
oxygen therapy, are ideally suited for use in a managed care environment and as
a tool for dealers to increase revenues and profits. To ensure continued
awareness of the benefits of the Company's products by chain headquarters
personnel, a proactive marketing and communications program has been initiated
with all of the major

national chains. Management believes that the consolidation activity being
experienced in the home oxygen business is temporary and should have no adverse
effects on the Com pany's growth.

Cost of sales as a percent of net sales decreased from 46.9% to 43.2% and from
47.3% to 43.1%, respectively, for the three and nine months periods ended
December 31, 1995, as compared to the prior year's periods. The current period
has been affected by decreased production costs associated with bringing certain
manufacturing operations in house. Management believes the cost per unit should
continue to decline in future periods as efficiencies of in house manufacturing
are assimilated in production.

Selling, general and administrative expenditures decreased as a percentage of
net sales for the three and nine months periods ended December 31, 1995, as
compared to the prior year's periods, from 25.9% to 23.2% and from 26.6% to
24.9%, respectively, as the rate of growth in sales exceeded the increased costs
associated with such growth. Research and development expenses increased in
1995. Management expects to spend increasing amounts in the upcoming year on
research and development to enhance and expand the Company's product line if
appropriate products can be identified.

At March 31, 1995, the Company had fully utilized its net operating loss
carryforwards for Federal income tax purposes and other tax credit
carryforwards. Future years will therefore be fully taxed and management
estimates that the combined Federal and California income tax rates will be
approximately 40%, as compared to 31.5% in 1995.

Financial Condition

At December 31, 1995, the Company had cash and marketable securities totaling
$1,948,000 or 21% of total assets, as compared to $1,635,000 (26%) at March 31,
1995. On June 30, 1994, the Company announced that the Board of Directors had
authorized stock repurchases of its common shares in privately negotiated
transactions for a minimum of 10,000 shares. In the current period, under this
plan the Company has used $392,000 in cash to purchase 71,000 common shares at
$5.50 per share, which shares have been retired. In addition, in the current
period the Company purchased approximately 12,000 shares of its own stock at a
cost of $228,000 for purposes of funding contributions to the Company's 401(k)
plan. Net working capital increased from $5,172,000 at March 31, 1995, to
$7,277,000 at December 31, 1995, in spite of the amounts utilized in the
aforementioned stock purchases. Accounts receivable increased $679,000 during
the period ended December 31, 1995, which related to increase in the sales
activity. Future increases or decreases in accounts receivable will generally
coincide

with sales volume fluctuations and the timing of shipments to foreign customers.
During the same period, inventories increased $1,636,000. The Company attempts
to maintain sufficient inventories to meet its customer needs as orders are
received. Thus, future inventory and related accounts payable levels will be
impacted by the ability of the Company to maintain its safety stock levels. If
safety stock levels drop below target amounts then inventories in subsequent
periods will increase more rapidly as inventory balances are replenished.

While historically the Company had relied upon the proceeds derived from the
sale of securities to finance its operations, management believes funds derived
from operations should be adequate to meet the Company's present cash
requirements. The Company does not anticipate any material capital expenditures
during the next twelve months. However, the Company may make additional stock
repurchases pursuant to the Board of Directors authorization. The Company does
not provide post employment retirement bene fits.
