                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 RESULTS OF OPERATIONS AND FINANCIAL CONDITION

MEDICARE REIMBURSEMENT

     As a supplier of home oxygen and other respiratory therapy services for the
home health care market, the Company participates in Medicare Part B, the
Supplementary Medical Insurance Program, which was established by the Social
Security Act of 1965. Suppliers of home oxygen and other respiratory therapy
services have historically been heavily dependent on Medicare reimbursement due
to the high proportion of elderly suffering from respiratory disease.

     On August 5, 1997, the Balanced Budget Act of 1997 ("BBA") was signed into
law. The legislation, among other things, was intended to reduce Medicare
expenditures by $115 billion over five years. The BBA reduced Medicare
reimbursement amounts for oxygen and oxygen equipment furnished after January 1,
1998, to 75 percent of the fee schedule amounts in effect during 1997.
Reimbursement amounts for oxygen and oxygen equipment furnished after January 1,
1999, and each subsequent year thereafter, were reduced to 70 percent of the fee
schedule amounts in effect during 1997. The BBA also reduced payment amounts for
covered drugs and biologicals furnished after January 1, 1998 to 95 percent of
the average wholesale price of such covered items.

     The BBA authorizes the Department of Health and Human Services to conduct
up to five competitive bidding demonstration projects for the acquisition of
durable medical equipment and requires that one such project be established for
oxygen and oxygen equipment. Each demonstration project is to be operated over a
three-year period and is to be conducted in not more than three competitive
acquisition areas. The first demonstration project became effective in Polk
County, Florida on October 1, 1999. The second demonstration project is
scheduled to become effective January 1, 2001 in the San Antonio, Texas area.
The BBA also includes provisions designated to reduce health care fraud and
abuse including a surety bond requirement, which has not yet been implemented,
for durable medical equipment providers.

     On November 29, 1999, the Balanced Budget Refinement Act of 1999 ("BBA
Refinement Act") was signed into law. This legislation was designed to mitigate
the effects of the Balanced Budget Act of 1997 ("BBA") on health care providers.
The BBA Refinement Act restores approximately $1.2 billion in funding in 2000
and $16 billion over five years, and affects a wide range of health care
providers. With respect to the services provided by the Company, the BBA
Refinement Act provides for temporary increases in Medicare payment rates for
durable medical equipment (including oxygen equipment) of 0.3% in 2001 and 0.6%
in 2002. Furthermore, the BBA Refinement Act temporarily prohibits the
Department of Health and Human Services from exercising its inherent
reasonableness authority to reduce payments for non-physician Part B services,
including durable medical equipment, and excludes durable medical equipment from
the home health consolidated billing requirements established in the BBA.

     Federal and state budgetary and other cost-containment pressures will
continue to impact the home respiratory care industry. The Company cannot
predict whether new federal and state budgetary proposals will be adopted or the
effect, if any, such proposals would have on the Company's business.

</TABLE>

     Net revenues for the three months ended March 31, 2000 increased by
$23,416,000 (or 17.2%) compared with the three months ended March 31, 1999.
Internally generated growth increased revenues by approximately $13,840,000 (or
10.2%) for the three months ended March 31, 2000. Growth due to acquisitions
increased revenues by approximately $9,576,000 (or 7.0%) for the three months
ended March 31, 2000.

     Cost of goods and services as a percentage of net revenues were 15.3% for
the three months ended March 31, 2000 compared with 15.9% for the three months
ended March 31, 1999.

     Operating expenses as a percentage of net revenues were 22.5% for the three
months ended March 31, 2000 as compared to 22.7% for the three months ended
March 31, 1999. Selling, general and administrative expenses as a percentage of
net revenues were 21.4% for the three months ended March 31, 2000 compared with
22.0% for the three months ended March 31, 1999. The Company has been able to
maintain a cost structure that, with increases in net revenues, allows the
Company to spread its overhead across a larger base of revenue, resulting in
improvements in operating income.

     Amortization expense for the three months ended March 31, 2000 increased to
$4,266,000 compared with $3,790,000 for the three month period ending March 31,
1999. The increase is attributable to the amortization of intangible assets
associated with business combinations in 1999 and the first three months of
2000.

     Operating income for the three months ended March 31, 2000 increased to
$47,113,000, compared with $38,579,000 for the three ended March 31, 1999. The
increases in operating income are attributable to the continued revenue growth
and efforts to control costs.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash provided from operating activities was $49,430,000 for the three
months ended March 31, 2000 compared with $42,268,000 for the three months ended
March 31, 1999.

     Net cash used in investing and financing activities was $52,724,000 for the
three months ended March 31, 2000. Activity during the three month period ended
March 31, 2000 included the Company's investment of $22,050,000 in business
acquisitions, investment in capital equipment of $18,242,000, proceeds of
$34,000,000 from long-term obligations, payments of $26,089,000 related to
long-term obligations and $21,676,000 to acquire treasury stock.

     As of March 31, 2000, the Company's principal sources of liquidity
consisted of $67,607,000 of working capital and $86,630,000 available under its
bank-credit facilities. The Company believes that internally generated funds,
together with funds that may be borrowed under such credit facility, will be
sufficient to meet the Company's anticipated capital requirements for the
foreseeable future.

     On June 11, 1999, the Company's Board of Directors authorized the Company
to repurchase up to $200,000,000 of its outstanding common stock. Purchases are
made through open market or privately negotiated transactions, subject to market
conditions and trading restrictions. As of March 31, 2000, $139,935,000 of
common stock had been repurchased under this program.

QUANTITATIVE AND QUALITATIVE DISCLOSURE REGARDING MARKET RISK

     During September 1999 as part of the Company's stock repurchase program,
the Company sold European Put Options ("Puts") on underlying shares of the
Company's common stock. The Puts originally had a six-month maturity period and
the Company was paid a $4,454,000 premium in advance which was accounted for as
additional paid-in capital. On March 3, 2000, the Company amended the terms of
the Puts to extend the maturity date of the Puts by two months. In connection
with extending the maturity period of the Puts, the Company was paid an
additional cash premium of $280,000. The Company has the option to settle the
Puts in cash or in shares of common stock. If the market price of the Company's
common stock is less than the strike price of the Puts at maturity, the Company
may either purchase 1,000,000 shares of its common stock for $28,282,000, settle
the Puts in cash based on the difference between the market price of the
Company's common stock and the strike price of the Puts or settle the Puts in
shares of common stock by issuing additional shares of common stock at the
current market value. As of March 31, 2000, the market price of the Company's
common stock was $28.38 and the average strike price of the Puts was $28.28.

     The Company is exposed to changes in interest rates as a result of its bank
credit agreement which is based on the London Interbank Offered Rate. A 10%
increase in interest rates related to the Company's bank credit facility would
not have a material effect on the Company's earnings over the next fiscal year
or the bank credit agreement's fair value.
