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

BALANCED BUDGET ACT OF 1997

     On August 5, 1997, the Balanced Budget Act of 1997 ("BBA") was signed into
law. The BBA reduces Medicare payment amounts for oxygen and oxygen equipment
furnished after January 1, 1998, to 75 percent of the fee schedule amounts in
effect during 1997. Payment amounts for oxygen and oxygen equipment furnished
after January 1, 1999, and each subsequent year are reduced to 70 percent of the
fee schedule amounts in effect during 1997.

     The BBA freezes the Consumer Price Index (U.S. urban average) update for
covered items of durable medical equipment for each of the years 1998 through
2002 while limiting fees for parenteral and enteral nutrients, supplies and
equipment to 1995 reasonable charge levels over the same period. The BBA reduces
payment amounts for covered drugs and biologicals to 95 percent of the average
wholesale price of such covered items for each of the years 1998 through 2002.

     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 BBA also includes provisions designated
to reduce health care fraud and abuse including a surety bond requirement for
durable medical equipment providers.

</TABLE>

     Net revenues for the three months ended September 30, 1999 increased by
$24,556,000 (or 19.5%) compared with the three months ended September 30, 1998,
and for the nine months ended September 30, 1999 increased $72,240,000 (or
20.2%) compared with the nine months ended September 30, 1998. The price cuts
attributable to the BBA reduced the Company's revenues by approximately
$4,998,000 and $14,203,000 for the three and nine months ended September 30,
1999. Excluding the effect on the Company's revenues from the Medicare price
reductions, internally generated growth increased revenues by approximately
$15,827,000 (or 12.6%) and $43,475,000 (or 12.2%) for the three and nine months
ended September 30, 1999. Growth due to acquisitions increased revenues by
approximately $13,727,000 (or 10.9%) for the three months ended September 30,
1999 and $42,968,000 (or 12.0%) for the nine months ended September 30, 1999
over the comparable prior year period.

     Cost of goods and services as a percentage of net revenues were 15.4% for
the three months ended September 30, 1999 compared with 15.1% for the three
months ended September 30, 1998. Costs of goods and services as a percentage of
net revenues were 15.6% for the nine months ended September 30, 1999 and
September 30, 1998.

     Operating expenses as a percentage of net revenues were 22.6% for the three
months ended September 30, 1999 as compared to 22.4% for the three months ended
September 30, 1998. Operating expenses as a

percentage of net revenues were 22.7% for the nine months ended September 30,
1999 compared with 23.1% for the nine months ended September 30, 1998.

     Selling, general and administrative expenses as a percentage of net
revenues were 22.1% for the three months ended September 30, 1999 compared with
21.9% for the three months ended September 30, 1998. Selling, general and
administrative expenses as a percentage of net revenues were 22.1% for the nine
months ended September 30, 1999 compared with 22.3% for the nine months ended
September 30, 1998.

     Amortization expense for the three months ended September 30, 1999
increased to $4,091,000 compared with $3,328,000 for the three month period
ending September 30, 1998. Amortization expense for the nine months ended
September 30, 1999 increased to $11,858,000 compared with $9,279,000 for the
nine month period ended September 30, 1998. The increase is attributable to the
amortization of intangible assets associated with business combinations in 1998
and the first nine months of 1999.

     Operating income for the three and nine months ended September 30, 1999
increased to $43,500,000 and $122,885,000, respectively, compared with
$37,284,000 and $100,301,000 for the three and nine months ended September 30,
1998. The increases in operating income are attributable to the continued
revenue growth and efforts to control costs. The Company has been able to
maintain a cost structure that, with increases in net revenue, allows the
Company to spread its fixed costs over a larger base of revenues, resulting in
improvements in operating income.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash provided from operating activities was $116,808,000 for the nine
months ended September 30, 1999 compared with $113,255,000 for the nine months
ended September 30, 1998.

     Net cash used in investing and financing activities was $109,548,000 for
the nine months ended September 30, 1999 compared with $106,112,000 for the nine
months ended September 30, 1998. Activity during the nine-month period ended
September 30, 1999 included the Company's investment of $50,500,000 in business
acquisitions, investment in capital equipment of $51,577,000, proceeds of
$262,000,000 from long-term obligations and payments of $160,234,000 related to
long-term obligations. For the nine month period ended September 30, 1999 as
compared to the nine month period ended September 30, 1998, the cash proceeds
and tax benefit resulting from employee stock options exercised decreased cash
flow by approximately $13,700,000.

     As of September 30, 1999, the Company's principal source of liquidity
consisted of $63,796,000 of working capital and $110,000,000 available under its
revolving credit loan and line of credit. On August 23, 1999, the Company
entered into a new revolving credit loan and line of credit, increasing its
borrowing capacity from $100,000,000 to $265,000,000 as of September 24, 1999.
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 will
be made through open market or privately negotiated transactions, subject to
market conditions and trading restrictions. During the three months ended
September 30, 1999, $113,966,000 of common stock had been repurchased.

YEAR 2000 REMEDIATION

     Certain risks may exist with respect to potential malfunctions of computer
hardware and software and embedded microprocessors due to the upcoming change in
the century (the "Year 2000 problem"). Malfunctions may arise due to the design
of microchips and microprocessors and computer systems that are programmed to
use two rather than four digits to define the applicable year. The Company is
involved in an extensive, ongoing program to identify and remediate potential
issues arising from the Year 2000 problem.

     The Company uses a proprietary and internally developed management
information system (MIS) which serves as the platform for the operating and
financial activities of the Company. The MIS system processes

                                        8
<PAGE>   9

billings to and collections from third party payors for services provided by the
Company and supports all of the Company's accounting, finance and general ledger
functions. The system provides management with information used to measure and
evaluate performance levels throughout the Company including revenues and
profitability, accounts receivable and collections, equipment controls and
utilization, customer activity and manpower trends. The Company has completed,
in all material respects, the conversion of its mission-critical MIS software
thereby mitigating the risk of Year 2000 problems. The costs associated with
this conversion were immaterial and fully expensed in the prior fiscal year.

     The Company has assessed its use of ancillary, third party computer
software used to electronically submit medical claims to certain payors. In the
event that the use of this software is impacted by the Year 2000 problem, the
Company's contingency plan includes the submission of paper claims to such
payors. The Company does not believe that this will have a material effect on
the Company's ability to receive payment for services rendered.

     Certain medical devices and equipment provided by the Company to its
customers may contain embedded technology such as microprocessors that could be
affected by the Year 2000 problem. The Company has identified those categories
of devices and equipment that may be sensitive to the change in century, and has
developed a plan to determine the Year 2000 status of specific items. In the
event that the Company identifies specific devices and equipment that are not
Year 2000 compliant, or the Company is unable to determine the status of such
items, the Company will remove such items from service and replace them with
therapeutically comparable, Year 2000 compliant equipment from alternate
vendors. The Company does not believe that the scope and cost of exchanging
non-compliant devices and equipment will have a material impact on the Company's
financial position.

     The Company is highly dependent upon certain government and private payors
for payment of claims for services and equipment provided by the Company. The
Company is in the process of determining the Year 2000 compliance of computer
systems used by third party payors to process claims for medical services and
equipment submitted by the Company for payment. The Company cannot be assured of
the timely remediation of third party claims processing and payment systems. The
failure by a significant third party payor to correct Year 2000 problems, to the
extent that such issues delay or prevent timely or appropriate payment of
claims, could have a material impact on the Company's cash flow from operations.
The Company is monitoring the Year 2000 progress of Medicare Part B carriers,
and other government agencies and private payors with which the Company does
significant business, to determine the potential impact to the Company. The
Company is also in the process of determining the contingency plans of these
payors to release payments to providers such as the Company in the event of
claims processing system failures. Such plans may include cash advances to
providers based on historical payment trends or processing claims on paper

     During September 1999 as part of the Company's stock repurchase program,
the Company has sold European Put Options ("Puts") on underlying shares of the
Company's stock. The Puts have 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. The Company has the option to settle the Puts in cash or in shares
of its common stock for $28,282,000 at maturity based on the market price of the
Company's common stock relative to the strike price of the Puts.

     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.
