                    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 designed 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 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 September 30, 2000 increased by
$35,775,000 (or 23.8%) compared with the three months ended September 30, 1999.
Net revenues for the nine months ended September 30, 2000 increased $83,787,000
(or 19.5%) compared with the nine months ended September 30, 1999. The increase
in net revenues is attributable to market gains in the Company's core
respiratory business, the acquisition of complementary businesses and geographic
expansion through the opening of new operating centers in contiguous and new
geographic markets.

     Cost of goods and services as a percentage of net revenues were 17.0% for
the three months ended September 30, 2000 compared with 15.4% for the three
months ended September 30, 1999. Costs of goods and services as a percentage of
net revenues were 16.0% for the nine months ended September 30, 2000 compared
with 15.6% for the nine months ended September 30, 1999. The increase in cost of
goods is the result of the Company's purchase of the assets of United Medical,
Inc. ("UMI") on June 28, 2000. The UMI locations operated by the Company provide
a more broad base of durable medical equipment and supplies which have lower
gross margins than the Company's traditional core respiratory business.

     Operating expenses as a percentage of net revenues were 22.7% for the three
months ended September 30, 2000 as compared with 22.6% for the three months
ended September 30, 1999. Operating expenses as a percentage of net revenues
were 22.6% for the nine months ended September 30, 2000 as compared with 22.7%
for the nine months ended September 30, 1999. Selling, general and
administrative expenses as a percentage of net revenues were 20.6% for the three
months ended September 30, 2000 as compared with 22.1% for the three months
ended September 30, 1999. Selling, general and administrative expenses as a
percentage of net revenues were 21.1% for the nine months ended September 30,
2000 as compared with 22.1% for the nine months ended September 30, 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 September 30, 2000
increased to $5,302,000 compared with $4,091,000 for the three month period
ended September 30, 1999. Amortization expense for the nine months ended
September 30, 2000 increased to $14,296,000 compared with $11,858,000 for the
nine month period ended September 30, 1999. The increase is attributable to the
amortization of intangible assets associated with business combinations in 1999
and the first nine months of 2000.

     Operating income for the three months and nine months ended September 30,
2000 increased to $53,386,000 and $149,455,000, respectively, compared with
$43,500,000 and $122,885,000 for the three and nine months ended September 30,
1999. The increases in operating income are attributable to the continued
revenue growth and efforts to control costs.

     Interest expense for the three and nine months ended September 30, 2000
increased to $5,667,000 and $12,491,000, respectively, compared with $1,512,000
and $2,909,000 for the three and nine months ended September 30, 1999. The
increases in interest expense are attributable to additional long term debt used
to repurchase the Company's common stock on the open market and the purchase of
the assets of UMI on June 28, 2000.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash provided from operating activities was $145,320,000 for the nine
months ended September 30, 2000 compared with $116,808,000 for the nine months
ended September 30, 1999.

                                        8
<PAGE>   9

     Net cash used in investing and financing activities was $148,399,000 for
the nine months ended September 30, 2000. Activity during the nine-month period
ended September 30, 2000 included the Company's investment of $150,238,000 in
business acquisitions, investment in capital equipment of $43,935,000, proceeds
of $311,000,000 from long-term obligations, payments of $206,742,000 related to
long-term obligations and $59,748,000 to acquire treasury stock.

     As of September 30, 2000, the Company's principal sources of liquidity
consisted of $76,982,000 of working capital and $84,000,000 available under its
three-year bank credit facility. The Company's $60,000,000 364-day revolving
credit facility expired on August 22, 2000 and was replaced on September 6, 2000
by $125,000,000 of senior secured notes offered through a private placement. The
senior secured notes have a fixed interest rate and mature over three, four and
five years: $30,000,000 at 8.91% due September 15, 2003, $50,000,000 at 9.01%
due September 15, 2004 and $45,000,000 at 9.11% due September 15, 2005. Upon
entering into the senior secured note agreement an organization fee of $893,000
was paid and is being amortized over the periods of the notes. The Company
believes that internally generated funds, together with funds that may be
borrowed under its three-year bank 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 September 30, 2000, $178,008,000 of
common stock had been repurchased under this program.

NEW ACCOUNTING STANDARDS

     In June 1999, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 137, "Accounting for Derivative
Instruments and Hedging Activities -- Deferral of the Effective Date of SFAS No.
133," which deferred, for one year, the effective date for the implementation of
SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities".
SFAS No. 133 requires that an entity recognize all derivative instruments as
either assets or liabilities on the balance sheet and measure those instruments
at fair values. The Company will be required to adopt this standard for
financial statements issued beginning the first quarter of fiscal year 2001.

     On September 6, 2000 the Company entered into interest rate swap agreements
whereby the interest rate on its $125,000,000 of senior secured notes were
effectively converted to variable interest rates based on three-month LIBOR plus
a fixed spread. At September 30, 2000 the swap-adjusted interest rates on the
three, four and five-year senior secured notes were 8.65%, 8.72% and 8.81%. On
September 7, 2000, the Company entered into an interest rate collar transaction
with an initial notional amount of $125,000,000. The collar has a floor rate of
5.81% and a cap rate of 8.00% with a floating rate option based on three-month
LIBOR. The notional amount of the collar amortizes in accordance with the
maturity dates of the underlying senior secured notes. The Company has estimated
the fair value of its interest rate swap agreements at September 30, 2000 and
does not anticipate the implementation of SFAS No. 133 to have a material effect
on its financial statements.

     The Company is exposed to changes in interest rates as a result of its
three-year bank credit facility and its interest rate swap contracts associated
with the senior secured notes which are based on the London Interbank Offered
Rate. A 10% increase in interest rates related to the three-year bank credit
facility and the interest rate swap contracts would not have a material effect
on the Company's earnings over the next fiscal year or the value of the bank
credit facility and the interest swap contracts.

FORWARD LOOKING STATEMENTS

     Statements contained herein that are not based on historical facts are
forward-looking statements that are based on projections and estimates regarding
the economy in general, the health care industry and other factors which impact
the Company. These statements involve known and unknown risks, uncertainties and
other factors that may cause the Company's actual results, levels of activity,
performance or achievements to be materially different from any results, levels
of activity, performance or achievements expressed or implied

                                        9

by any forward-looking statements. The estimates relate to reimbursement by
government and third party payors for the Company's products and services, the
costs associated with government regulation of the health care industry and the
effects of competition and industry consolidation. In some cases,
forward-looking statements that involve risks and uncertainties contain
terminology such as "may," "will," "should," "could," "expects," "intends,"
"plans," "anticipates," "believes," "estimates," "predicts," "potential" or
"continue" or variations of these terms or other comparable terminology.

     Key factors that have an impact on the Company's ability to attain these
estimates include potential reductions in reimbursement rates by government and
third party payors, changes in reimbursement policies, demand for the Company's
products and services, the availability of appropriate acquisition candidates
and the Company's ability to successfully complete acquisitions, efficient
operations of the Company's existing and future operating facilities, regulation
and/or regulatory action affecting the Company or its business, economic and
competitive conditions and access to borrowed and/or equity capital on favorable
terms.

     In developing its forward-looking statements, the Company has made certain
assumptions relating to reimbursement rates and policies, internal growth and
acquisitions and the outcome of various legal and regulatory proceedings. If the
assumptions used by the Company differ materially from what actually occurs,
then actual results could vary significantly from the performance projected in
the forward-looking statements. The Company is under no duty to update any of
the forward-looking statements after the date of this Form 10-Q.

PART II.  OTHER INFORMATION

Item 1  Legal Proceedings

     From time to time, the Company receives inquiries from various government
agencies requesting patient records and other documents. It has been Lincare's
policy to cooperate with all such requests for information. The government has
not instituted any proceedings or served Lincare with any complaints as a result
of these inquiries.

     Private litigants may also make claims against the Company for violations
of health care laws in actions known as qui tam suits and the government may
intervene in, and take control of, such actions. The Company is a defendant in
certain qui tam proceedings. Lincare intends to vigorously defend these suits
should they proceed. The government has declined to intervene in all unsealed
qui tam actions of which the Company is aware.

     As a health care provider, Lincare is subject to extensive government
regulation, including numerous laws directed at preventing fraud and abuse and
laws regulating reimbursement under various government programs. The marketing,
billing, documentation and other practices of health care companies are all
subject to government scrutiny. To ensure compliance with Medicare and other
regulations, regional carriers often conduct audits and request patient records
and other documents to support claims submitted by the Company for payment of
services rendered to patients. Similarly, government agencies periodically open
investigations and obtain information from health care providers pursuant to
legal process.

     Violations of federal and state regulations can result in severe criminal,
civil and administrative penalties and sanctions, including disqualification
from Medicare and other reimbursement programs.
