              NOTES TO UNAUDITED PRO FORMA COMBINED BALANCE SHEET
 
1. BASIS OF PRESENTATION
 
  The Unaudited Pro Forma Combined Balance sheet of Total Renal Care Holdings,
Inc. as of September 30, 1996 gives effect to the acquisition of individually
insignificant acquisitions consummated during the period October 1, 1996 to
October 30, 1996 and individually insignificant acquisitions which were
probable as of October 30, 1996, in each case as if such acquisitions were
consummated on September 30, 1996. The pro forma adjustments are based on
consideration exchanged, including the estimated fair value of assets acquired
and liabilities assumed. The actual adjustments, which will be based on
valuations of fair value as of the date of acquisition, may differ from those
made herein.
 
2. PRO FORMA ADJUSTMENTS
 
  (a) To record the combined acquisitions as follows (in thousands):
 

<TABLE>
   <S>                                                                  <C>
   Purchase price...................................................... $32,335
   Net book value of assets acquired...................................   6,009
                                                                        -------
   Purchase price allocated to intangible assets....................... $26,326
                                                                        =======
</TABLE>

 
  The purchase prices of the consummated and probable combined acquisitions
will be paid with cash of $1,045,000 and borrowings of $31,290,000.
 
  (b) To reflect assets and liabilities not acquired by the Company.
 
  (c) To eliminate the equity of the acquired businesses.
 
  (d) To eliminate the minority interest related to the acquisition of the
remaining interest in a facility. The facility balances are included in both
the Company historical totals and the Other Combined Acquisitions historical
totals and, therefore, are adjusted in the Pro Forma Adjustments column.

          NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENTS OF INCOME
 
1. BASIS OF PRESENTATION
 
  The Unaudited Pro Forma Combined Statement of Income for the nine months
ended September 30, 1996 gives effect to the acquisition by the Company of the
Nephrology Services Business of Caremark International Inc. on March 15, 1996
(the "Caremark Facilities"), two facilities located in South Carolina on March
15, 1996 (the "South Carolina Facilities") and individually insignificant
acquisitions consummated during the period January 1, 1996 through October 30,
1996, and individually insignificant acquisitions which were probable as of
October 30, 1996, in each case as if such acquisitions were consummated on
January 1, 1996. The Unaudited Pro Forma Combined Statement of Income for the
nine months ended September 30, 1996 also gives effect to the retirement of
all outstanding 12% Senior Subordinated Discount Notes in July and September
1996 (the "Debt Retirement") as if it occurred on January 1, 1996.
 
  The Unaudited Pro Forma Combined Statement of Income for the seven months
ended December 31, 1995 gives effect to the acquisition by the Company of
three facilities located in the Miami area on July 17, 1995 (the "Miami
Facilities"), two facilities located in Texas on December 1, 1995 (the
"Southwest Facilities"), the Caremark Facilities, the South Carolina
Facilities and individually insignificant acquisitions consummated during the
period June 1, 1995 through October 30, 1996, and individually insignificant
acquisitions which were probable as of October 30, 1996, in each case as if
such acquisitions were consummated on June 1, 1995. The Unaudited Pro Forma
Combined Statement of Income for the seven months ended December 31, 1995 also
gives effect to the Company's initial public offering on October 30, 1995 (the
"Initial Public Offering"), the Company's secondary offering on April 3, 1996
(the "Secondary Offering") and the Debt Retirement as if such transactions
occurred on June 1, 1995.
 
  The Unaudited Pro Forma Combined Statement of Income for the fiscal year
ended May 31, 1995 gives effect to the acquisition by the Company of five
facilities located in the Chicago area on May 1, 1995 (the "Chicago
Facilities"), the Miami Facilities, the Caremark Facilities, the South
Carolina Facilities and individually insignificant acquisitions consummated
during the period June 1, 1994 through October 30, 1996, and individually
insignificant acquisitions which were probable as of October 30, 1996, in each
case as if such acquisitions were consummated on June 1, 1994. The Southwest
Facilities, which commenced operations in April 1995, had de minimis
operations during the twelve months ended May 31, 1995 and, therefore, are not
included in the Unaudited Pro Forma Combined Statement of Income for the
fiscal year ended May 31, 1995. The Unaudited Pro Forma Combined Statement of
Income for the fiscal year ended May 31, 1995 also gives effect to the sale by
Tenet Healthcare Corporation of approximately 75% of its ownership interest in
the Company to DLJ Merchant Banking Partners, L.P. and certain of its
affiliates in August 1994 (the "August 1994 Transaction"), the Initial Public
Offering, the Secondary Offering and the Debt Retirement as if such
transactions occurred on June 1, 1994.
 
  The pro forma adjustments are based on consideration exchanged, including
the estimated fair value of assets acquired, liabilities assumed and common
stock issued. The actual adjustments, which will be based on valuations of
fair value as of the date of acquisition, may differ from those made herein.
 
  Net income per common share data and weighted average number of shares and
equivalents outstanding for the nine months ended September 30, 1996, for the
seven months ended December 31, 1995 and for the fiscal year ended May 31,
1995 assume that any shares issued in connection with the acquisitions were
outstanding from January 1, 1996 and June 1, 1995 and 1994, respectively.
 
2. PRO FORMA ADJUSTMENTS
 
  (a) To reflect the redemption of 12% Senior Subordinated Discount Notes as
if it occurred on January 1, 1996. Specifically to reduce interest expense
assuming the redemption, offset by borrowings under the Senior Credit Facility
and further offset by interest income foregone.
 
  During the quarter ended September 30, 1996, the Company repurchased $65
million, at maturity, of the 12% Senior Subordinated Discount Notes for $67.3
million resulting in an extraordinary loss, net of tax, of $7.7 million which
is not included in the Unaudited Pro Forma Combined Statement of Income.

resulting from the acquisitions on a straight-line basis over 25, 10 or 5
years, respectively.
 
  (d) To eliminate interest expense on borrowings not assumed by the Company.
 
  (e) To record interest expense resulting from acquisitions funded in whole
or in part by borrowings from the senior credit facility.
 
  (f) To record income tax effects related to the pro forma adjustments.
 
  (g) To record the minority interest income from five partnerships acquired.
 
  (h) Income per share and weighted average number of common shares and
equivalents outstanding assume 62,000 shares and share equivalents issued to
purchase the individually insignificant acquisitions were outstanding for the
entire nine-month period ended September 30, 1996.
 
  Income per share and weighted average number of common shares and
equivalents outstanding also assume that shares issued in the Secondary
Offering to the extent that cash generated from such shares were used to
purchase facilities and were outstanding from January 1, 1996 to the date of
the Secondary Offering as follows:

  (i) To reflect the Initial Public Offering and subsequent use of proceeds to
redeem 12% Senior Subordinated Discount Notes as if it occurred on June 1,
1995. Specifically, to reduce interest expense assuming paydown of a portion
of the 12% Senior Subordinated Discount Notes and amounts outstanding under
the line of credit. On December 7, 1995 the Company redeemed 35% of the
accreted value of the 12% Senior Subordinated Discount Notes equaling
$28,749,000 at a redemption premium of 111% for a redemption price of
$31,912,000. An extraordinary loss of $2,555,000 (net of income tax effect)
resulted from this transaction which is not included on the Unaudited Pro
Forma Combined Statement of Income. The additional reduction in interest
expense incurred under the line of credit assumes that cash generated by the
stock offering was used to purchase all facilities acquired and that the line
of credit was not drawn for these acquisitions.

alone entity, increases in interest expense ($1,811,000), amortization
expenses ($105,000) and bank fees ($42,000) related to the issuance of the 12%
