Services, LLC, a Georgia limited liability company ("SGDS") which operated four
dialysis facilities. The purchase price of $4,500,000 was paid in cash at
closing. The consolidated financial statements reflect the results of operations
of the acquired business from the acquisition date. A portion of the purchase
price was allocated to the net assets acquired based on their estimated fair

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
         RESULTS OF OPERATIONS.



OVERVIEW

         The Company, operating through its wholly-owned subsidiaries, is a
provider of dialysis and ancillary services to patients with end-stage renal
disease, as well as acute dialysis services to patients in hospitals. Since
inception, the Company has implemented a growth strategy designed to build its
presence in selected regional markets by establishing local clusters of dialysis
facilities through new facility ("DE NOVO") development or the acquisition of
existing facilities. To date, the Company has grown primarily through DE NOVO
development because the Company believes such a strategy minimizes the initial
capital outlay. However, DE NOVO facilities achieve profitability only when they
reach sufficient utilization, which historically does not occur prior to twelve
months following opening. The Company has increased utilization in its existing
facilities from an average of 41% at December 31, 1994 to an average of 68% at
September 30, 1998 primarily through marketing efforts directed at local
nephrologists, patients and managed care organizations. The Company's overall
facility utilization of 59% as of September 30, 1998 decreased from 66% as of
September 30, 1997 due to the opening of three facilities during the year and
the acquisition of four dialysis clinics in March 1998 which had a combined
utilization of 39%.

         As of September 30, 1998, the Company operated 20 outpatient dialysis
facilities, of which 11 were opened between 1994 and 1998. In addition, from
1995 through 1998, the Company acquired via the purchase of stock or assets,
nine dialysis facilities.

         In addition to its outpatient dialysis facilities, the Company manages
a home hemodialysis program and provides acute dialysis and hemapheresis
treatments to 14 hospitals through contractual arrangements with these
hospitals. The majority of these hospital contracts were added during the fourth
quarter of 1997 when the Company acquired certain assets of an acute dialysis
and hemapheresis company.

         The following table sets forth certain income statement items expressed

THREE MONTHS ENDED SEPTEMBER 30, 1998 AND 1997

         NET REVENUES. Net revenues for the three months ended September 30,
1998 were $10.2 million compared to $6.6 million for the same period in 1997,
representing an increase of 55%. The increase in net revenues was primarily
attributable to revenues for four new dialysis facilities acquired in March 1998
and an acute service company acquired in December 1997 totaling $1.5 million;
one DE NOVO facility opened in September 1997 and another facility opened in
March 1998 totaling $1.1 million and the continued growth at existing facilities
of $919,000.

         FACILITIES EXPENSES. Facilities expenses primarily consist of costs and
expenses specifically attributable to the operation of the dialysis facilities,
including operating and maintenance costs of such facilities and all labor,
supplies and service costs related to patient care. Facilities expenses for the
three months ended September 30, 1998 were $7.4 million compared to $5.0 million
for the same period in 1997, representing an increase of 48%. The increase in
facilities expenses was due to the greater number of facilities in operation in
1998. As a percentage of net revenues, facilities expenses decreased to 72.9%
for the three months ended September 30, 1998 from 76.2% for the same period in
1997. The decrease as a percentage of net revenues was attributable to an
increase in the commercial insurance payor mix from 20% for the three months
ended September 30, 1997 to 23% for the three months ended September 30, 1998
and the increase in acute dialysis services which doubled to 6% of revenues
compared to the same period in the prior year. Both of these increases provide
higher margins.

         GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative
expenses consist of headquarter expenses including marketing, finance,
operations management, legal, quality assurance, information systems, billing
and collections and centralized accounting support. General and administrative
expenses for the three months ended September 30, 1998 were $1.4 million
compared to $851,000 for the same period in 1997, representing an increase of
64%. The increase in general and administrative expenses was due to increased
personnel related expenses to support the greater number of facilities in
operation, accruals related to management incentive programs and costs
associated with being a public company. As a percentage of net revenues, general
and administrative expenses increased to 13.7% for the three months ended
September 30, 1998 from 12.9% for the same period in 1997. The increase as a
percentage of net revenues was due to accruals related to management incentive
programs and an increase in costs associated with being a public company.

         PROVISION FOR DOUBTFUL ACCOUNTS. The provision for doubtful accounts is
a function of patient payor mix, collection experience and other factors. The
Company reserves for doubtful accounts in the period in which revenue is
recognized based on management's estimate of the net collectibility of accounts
receivable. The provision for doubtful accounts for the three months ended
September 30, 1998 was $254,000 compared to $269,000 for the same period in
1997, representing a decrease of 6%. As a percentage of net revenues, the
provision for doubtful accounts decreased to 2.5% for the three months ended
September 30, 1998 from 4.1% for the same period in 1997. The decrease was
primarily due to an emphasis on collections of aged amounts and an improvement
in the aging of the accounts receivable.

         DEPRECIATION AND AMORTIZATION EXPENSES. Depreciation and amortization
expenses for the three months ended September 30, 1998 were $658,000 compared to
$394,000 for the same period in 1997, representing an increase of 67%. The
increase was primarily due to the acquisition of four dialysis clinics, the
opening of three facilities in 1998, and the acquisition of an acute dialysis
and hemapheresis business. As a percentage of net revenues, depreciation and
amortization expenses increased to 6.5% for the three months ended September 30,
1998 from 6.0% for the same period in 1997 as a result of the above.

         NET INTEREST INCOME (EXPENSE). Net interest income for the three months
ended September 30, 1998 was $21,000 compared to net interest expense of
$278,000 for the same period in 1997, 



                                       7
<PAGE>   10

representing an income increase of $299,000. The increase was primarily due to
the payoff in October 1997 of the Company's subordinated debt and the investment
of the remaining proceeds from the Company's initial public offering ("IPO").

         NET INCOME (LOSS). The Company had net income of $439,000 for the three
months ended September 30, 1998 compared to a net loss of $278,000 for the same
period in 1997, an increase of $717,000.

NINE MONTHS ENDED SEPTEMBER 30, 1998 AND 1997

         NET REVENUES. Net revenues for the nine months ended September 30, 1998
were $27.3 million compared to $19.0 million for the same period in 1997,
representing an increase of 44%. The increase in net revenues was primarily
attributable to the acquisition of four dialysis clinics and an acute dialysis
and hemapheresis services company totaling $3.2 million, a full nine months' net
revenue totaling $1.9 million for a new facility opened in September 1997,
$600,000 for three facilities opened during 1998 and to the continued growth at
existing facilities of $2.5 million.

         FACILITIES EXPENSES. Facilities expenses for the nine months ended
September 30, 1998 were $20.3 million compared to $14.7 million for the same
period in 1997, representing an increase of 39%. The increase in facilities
expenses was due to the greater number of facilities in operation in 1997. As a
percentage of net revenues, facilities expenses decreased to 74.6% for the nine
months ended September 30, 1998 from 77.3% for the same period in 1997. The
decrease as a percentage of net revenues was attributable to an increase in the
commercial insurance payor mix from 18% for the nine months ended September 30,
1997 to 24% for the nine months ended September 30, 1998, and an increase in
acute dialysis services, both of which provide higher margins.

         GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative
expenses for the nine months ended September 30, 1998 were $3.7 million compared
to $2.2 million for the same period in 1997, representing an increase of 71%.
The increase in general and administrative expenses was due to increased
personnel and related expenses to support the greater number of facilities in
operation, accruals related to management incentive programs and costs
associated with being a public company. As a percentage of net revenues, general
and administrative expenses increased to 13.5% for the nine months ended
September 30, 1998 from 11.3% for the same period in 1997. The increase as a
percentage of net revenues was due to accruals related to management incentive
programs and an increase in costs associated with being a public company.

         PROVISION FOR DOUBTFUL ACCOUNTS. The provision for doubtful accounts
for the nine months ended September 30, 1998 was $748,000 compared to $761,000
for the same period in 1997 representing a decrease of 2%. As a percentage of
net revenues, the provision for doubtful accounts decreased to 2.7% for the nine
months ended September 30, 1998 from 4.0% for the same period in 1997. The
decrease was primarily due to an increased emphasis upon collection of aged
amounts and an improvement in the aging of the accounts receivable.

         DEPRECIATION AND AMORTIZATION EXPENSES. Depreciation and amortization
expenses for the nine months ended September 30, 1998 were $1.7 million compared
to $1.2 million for the same period in 1997, representing an increase of 47%.
The increase was primarily due to the acquisition of four dialysis clinics, the
opening of three facilities, and the acquisition of an acute dialysis and
hemapheresis business. As a percentage of net revenues, depreciation and
amortization expenses increased to 6.4% for the nine months ended September 30,
1998 from 6.2% for the same period in 1997 as a result of the above.

         NET INTEREST INCOME (EXPENSE). Net interest income for the nine months
ended September 30, 1998 was $247,000 compared to net interest expense of
$815,000 for the same period in 1997, representing an income increase of
approximately $1.1 million. The increase was primarily due to the payoff in
October 1997 of the Company's subordinated debt and the investment of the
remaining proceeds from the Company's IPO.

         NET INCOME (LOSS). The Company had net income of $964,000 for the nine
months ended September 30, 1998 compared to a net loss of $781,000 for the same
period in 1997, an increase of approximately $1.8 million.

LIQUIDITY AND CAPITAL RESOURCES

    The Company requires capital resources for maintenance, refurbishing and
expansion of existing facilities, acquisitions, DE NOVO facilities, working
capital and general corporate purposes. The Company intends to finance its
growth and working capital requirements, as well as purchases of additional
equipment and leasehold improvements, from cash on hand, cash generated from
operations and the Company's secured line of credit described below. As of
September 30, 1998, the Company had working capital of approximately $9.5
million of which $8.8 million consisted of cash and cash equivalents, compared
to working capital of $15.6 million of which $14.8 million consisted of cash and
cash equivalents and securities available for sale as of December 31, 1997. The
decreases were primarily a result of the cash purchase of four facilities for
$4.5 million and purchases of property and equipment primarily for three
facilities opened in 1998 for $3.1 million.

    Net cash provided by operating activities was $2.5 million for the nine
months ended September 30, 1998, compared to net cash provided by operating
activities of $709,000 for the nine months ended September 30, 1997. Net cash
provided by operating activities consists of the Company's net income, increased
by non-cash expenses such as depreciation, amortization and the provision for
doubtful accounts and adjusted by changes in components of working capital,
primarily accounts receivable and accrued expenses.

    The Company requires substantial working capital to cover the expenses and
initial losses of each DE NOVO facility. Once a DE NOVO facility is operational,
the Company is unable to bill for services until it receives a Medicare provider
number and the Medicare intermediary installs its electronic billing software at
the facility. For these reasons, there is generally a 90-day delay before the
Company will receive payment on its initial services at such facility. In
addition, the dialysis industry is characterized by long collection cycles
because Medicaid and private insurance carriers require substantial
documentation to support reimbursement claims and often take a substantial
amount of time to process claims. As a result, the Company requires significant
working capital to cover expenses during the collection process.

    Net cash used for investing activities was $2.8 million and $961,000 for the
nine months ended September 30, 1998 and 1997, respectively. The cash used in
1998 related primarily to the $4.5 million cash purchase of four facilities in
March 1998, along with $3.1 million for purchases of fixed assets, offset by the
sale of $5.1 million in securities available for sale. The cash used in 1997
consisted primarily of purchases of fixed assets of $997,000. Historically, the
Company's principal uses of cash in investing activities have been related to
purchases of new equipment and leasehold improvements for the Company's existing
facilities, the cost of development of additional facilities and acquisitions.
The Company opened a facility in March 1998 and two more facilities during the
third quarter.

    Net cash used for financing activities for the nine months ended September
30, 1998 was $593,000. This consisted primarily of payments on capital lease
obligations. Net cash provided by financing

activities for the nine months ended September 30, 1997 of $454,000 consisted
primarily of $1 million of net proceeds from a line of credit offset by $530,000
in payments on capital lease obligations.

    In April 1998, the Company obtained a $15 million secured line of credit
with a financial institution (the "Line of Credit"). Borrowings under the Line
of Credit are based on cash flow measurements, and bear interest ranging from
the lower of the LIBOR rate, plus 2.25% up to 2.75%, or the prime rate minus .5%
up to the prime rate depending on the Company's leverage ratio. The Line of
Credit will be utilized primarily for acquisitions and also provides working
capital advances via sublimits up to $5 million. The Line of Credit contains
certain financial covenants as to minimum net worth, leverage, capitalization
and cash flow ratios along with restrictions on new indebtedness and payment of
dividends. The Line of Credit replaced the Company's previous $4 million line of
credit, and due to restrictions on indebtedness, it also effectively replaced
the Company's $6 million lease line for equipment financing. As of September 30,
1998, the Company did not have any borrowings under the Line of Credit.

    The Company's long-term capital requirements depend on numerous factors,
including the rate at which the Company develops or acquires new facilities. In
addition, the Company has various on-going needs for capital, including: (i)
working capital for operations (including financing receivables as previously
described); and (ii) routine capital expenditures for the maintenance of
facilities, such as equipment and leasehold improvements. In order to implement
the Company's long-term growth strategy, the Company anticipates that capital
requirements will increase substantially from historical levels.

    The Company anticipates that the consideration to be paid for the
acquisition of new facilities will consist of cash, promissory notes, assumption
of liabilities and/or the issuance of common stock or securities convertible
into common stock. Currently, the Company does not have any agreements,
commitments or understandings regarding the acquisition of any facilities. The
Company believes that cash on hand, together with the Line of Credit, will be
sufficient to fund the Company's operations and to finance the Company's growth
strategy through the next 12 months. However, there can be no assurance that the
Company will not require substantial additional funds prior to such time.

INCOME TAX LOSS CARRYFORWARDS

    As of September 30, 1998, the Company had approximately $6.6 million of net
operating loss carryforwards that may be available to offset future taxable
income for federal income tax purposes. These net operating loss carryforwards
begin to expire in 2008.

POTENTIAL IMPACT OF INFLATION

    A majority of the Company's net revenue is subject to reimbursement rates
which are regulated by the federal government and do not automatically adjust
for inflation. These reimbursement rates are adjusted periodically based on
certain factors, including Congressional budget limitations, inflation, consumer
price indexes and costs incurred in rendering the services. Historically,
adjustments to reimbursement rates have had little relation to the actual cost
of doing business.

    The Company is not able to increase the amounts it bills for services
provided by its operations that are subject to Medicare and Medicaid
reimbursement rates. Operating costs, such as labor and supply costs, are
subject to inflation without corresponding increases in reimbursement rates.
Such increases may be significant and, as such, have a material adverse effect
on the Company's results of operations.

YEAR 2000

    In February 1998, the Company formed a committee to evaluate and develop an
action plan for computer systems issues related to the Year 2000 ("Y2K"). The
committee is evaluating Y2K issues related to third party internal systems used
by the Company. This committee has also begun evaluating the impact of Y2K
issues on the Company's payors and operating vendors to determine their current
status and plan of action for Y2K readiness.

    The Company recognizes its reliance on third parties for its operating and
financial computer output and processing. Based upon ongoing assessments, it
appears that the Company's existing internal software is either Y2K compliant or
that third parties are taking appropriate and timely steps to ensure Y2K
readiness. Testing, modifications and conversions of these third parties'
software are expected to be completed by December 31, 1998. Presently, the
Company's management does not foresee any significant costs related to these
potential modifications and conversions.

    The Company has formally communicated with its significant payors and
vendors and has requested a written statement regarding their Y2K readiness and
proof of their Y2K testing by the first quarter of 1999. In the event that a
vendor or payor fails to respond to the Company's request, the Company will then
contact alternative payors and vendors who appear to have greater Y2K readiness
and can provide the Company with the same supplies, equipment or services.

    The failure of any of the Company's significant payors or operating vendors
to be Y2K compliant could have a material adverse impact on the operations of
the Company.

SHARE REPURCHASE PROGRAM

     In November 1998, the Company's Board of Directors approved a share
repurchase program authorizing the Company to repurchase up to 500,000 shares of
common stock on the open market from time to time at prices acceptable to the
Company. As of the current date, no shares have been repurchased.
