                                 TRC GUARANTY
 
  GUARANTY, dated as of October 11, 1996, made by TOTAL RENAL CARE, INC. (the
"Guarantor") to THE BANK OF NEW YORK, as Administrative Agent (in such
capacity, the "Administrative Agent") (i) for itself and for the ratable
benefit of the Lenders, the Swing Line Lender and the Letter of Credit Issuer
and (ii) for each Lender and any affiliate of a Lender which from time to time
shall have entered into an Interest Rate Protection Agreement with Total Renal
Care Holdings, Inc. (the "Borrower").
 
  A. The Borrower is party to a Credit Agreement, dated as of October 11,
1996, by and among the Borrower, the lenders party thereto, BNY Capital
Markets, Inc. and Donaldson, Lufkin & Jenrette Securities Corporation, as
Arrangers, DLJ Capital Funding, Inc., as Documentation Agent, and the
Administrative Agent (as the same may be amended, extended, increased,
modified, refunded or refinanced from time to time, the "Credit Agreement").
The Credit Agreement provides that the Guarantor shall execute and deliver
this Guaranty.
 
  B. The Guarantor expects to derive substantial benefit from the Credit
Agreement and the making of the Loans and the issuance of the Letters of
Credit thereunder. The Guarantor acknowledges that the Administrative Agent,
the Documentation Agent, the Arrangers, the Swing Line Lender, the Letter of
Credit Issuer and the Lenders are relying on this Guaranty in entering into
and agreeing to make the Loans and issue the Letters of Credit and that the
Administrative Agent, the Documentation Agent, the Arrangers, the Swing Line
Lender, the Letter of Credit Issuer and the Lenders would not enter into the
Credit Agreement without the execution and delivery of this Guaranty.
 
  C. The Guarantor wishes to guarantee the obligations of the Borrower under
the Loan Documents and each Interest Rate Protection Agreement entered into
with any Lender or any affiliate of a Lender.
 
  In consideration of the premises and agreements herein contained and other
good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, and in order to induce the Administrative Agent, the
Documentation Agent, the Arrangers, the Swing Line Lender, the Letter of
Credit Issuer and the Lenders to enter into the Credit Agreement and to make
and maintain the Loans and to induce BNY to issue the Letters of Credit, the
Guarantor covenants and agrees as follows:

time).
 
  "Consideration": as of any date of determination, an amount equal to the
lesser of (a) the total "value" (within the meaning of Section 548 of the
Bankruptcy Code as in effect on the date hereof) given, directly or
indirectly, to the Guarantor during the period commencing on the date hereof
and ending on such date of determination, in exchange for its execution and
delivery of this Guaranty, and (b) the amount of "fair consideration" (within
the meaning of Article 10 of the New York Debtor Creditor Law as in effect on
the date hereof) given, directly or indirectly, to the Guarantor during the
period commencing on the date hereof and ending on such date of determination
in exchange for its execution and delivery of this Guaranty.
 
                                       1

 
  "Guarantor Obligations": all of the obligations and liabilities of the
Guarantor hereunder, whether fixed, contingent, now existing or hereafter
arising, created, assumed, incurred or acquired.
 
  "Lender Parties": the Administrative Agent, the Documentation Agent, the
Arrangers, the Letter of Credit Issuer and the Swing Line Lender.
 
  "Lender Party": any of the Lender Parties.
 
  "Net Worth": as of any date, the lesser of the following:
 
    (a) (i) all of the Guarantor's "property, at a fair valuation" (within
  the meaning of Section 101(32) of the Bankruptcy Code as in effect on the
  date hereof) on such date, less (ii) the sum of the Guarantor's "debts"
  (within the meaning of Section 101(12) of the Bankruptcy Code as in effect
  on the date hereof) on such date (exclusive of such "debts" in respect of
  this Guaranty), or
 
    (b) (i) the "fair salable value of the assets" (within the meaning of
  Article 10 of the New York Debtor Creditor Law as in effect on the date
  hereof) of the Guarantor on such date, less (ii) "the amount that will be
  required to pay the Guarantor's probable liability on its existing debts as
  they become absolute and matured" (as such phrase would be construed under
  Article 10 of the New York Debtor Creditor Law as in effect on the date
  hereof) on such date (exclusive of such "debts" in respect of this
  Guaranty).
 
  2. Guaranty
 
  (a) Subject to Section 2(b) hereof, the Guarantor hereby absolutely,
irrevocably and unconditionally guarantees the full and prompt payment when
due (whether at stated maturity, by acceleration or otherwise) of the Borrower
Obligations. This Guaranty constitutes a guaranty of payment, and no Lender
Party shall have any obligation to enforce any Loan Document or any Interest
Rate Protection Agreement or exercise any right or remedy with respect to any
collateral security thereunder by any action, including, without limitation,
making or perfecting any claim against any Person or any collateral security
for any of the Borrower Obligations prior to being entitled to the benefits of
this Guaranty. The Administrative Agent may, at its option, proceed against
the Guarantor in the first instance to enforce the Guarantor Obligations
without first proceeding against the Borrower or any other Person, and without
first resorting to any other rights or remedies, as the Administrative Agent
may deem advisable. In furtherance hereof, if any Lender Party is prevented by
law from collecting or otherwise hindered from collecting or otherwise
enforcing any Borrower Obligation in accordance with its terms, the
Administrative Agent, on behalf of such Lender Party, shall be entitled to
receive hereunder from the Guarantor after demand therefor, the sums which
would have been otherwise due had such collection or enforcement not been
prevented or hindered.
 
  (b) Notwithstanding anything to the contrary contained in this Guaranty, the
maximum liability of the Guarantor hereunder shall not, as of any date of
determination, exceed the lesser of (i) the highest amount that is valid and
enforceable against the Guarantor under principles of New York State contract
law, and (ii) the sum of (1) all Consideration received by the Guarantor as of
such date of determination, plus (2) 95% of the Net Worth of the Guarantor on
such date of determination. In calculating the maximum liability of the
Guarantor hereunder, full effect shall be given to any provision in any other
Indebtedness of or guaranteed by the Guarantor which for purposes of
applicable fraudulent transfer or similar laws provides that indebtedness
incurred under the Credit Agreement or under this Guaranty shall be deemed to
have been incurred prior to such other Indebtedness.
 
  (c) The Guarantor agrees that its Guarantor Obligations may at any time and
from time to time exceed the maximum liability of the Guarantor hereunder
without impairing this Guaranty or affecting the rights and remedies of any
Lender Party hereunder.
 
  3. Absolute Obligation
 
  Subject to Section 8, the Guarantor shall not be released from liability
hereunder unless and until the Revolving Credit Commitments and the Swing Line
Commitment have been terminated and either (a) the Borrower Obligations shall
have been indefeasibly paid in full, in cash, or (b) the Guarantor Obligations
shall
 
                                       2

 
have been paid in full, in cash. The Guarantor acknowledges and agrees that
(1) no Lender Party has made any representation or warranty to the Guarantor
with respect to the Borrower, its Subsidiaries, any Loan Document, any
Interest Rate Protection Agreement, or any agreement, instrument or document
executed or delivered in connection therewith or any other matter whatsoever,
and (2) the Guarantor shall be liable hereunder, and such liability shall not
be affected or impaired, irrespective of (A) the validity or enforceability of
any Loan Document, any Interest Rate Protection Agreement, or any agreement,
instrument or document executed or delivered in connection therewith, or the
collectability of any of the Borrower Obligations, (B) the preference or
priority ranking with respect to any of the Borrower Obligations, (C) the
existence, validity, enforceability or perfection of any security interest or
collateral security under any Loan Document, or any Interest Rate Protection
Agreement, or the release, exchange, substitution or loss or impairment of any
such security interest or collateral security, (D) any failure, delay, neglect
or omission by any Lender Party to realize upon any direct or indirect
collateral security, indebtedness, liability or obligation, any Loan Document,
any Interest Rate Protection Agreement, or any agreement, instrument or
document executed or delivered in connection therewith, or any of the Borrower
Obligations, (E) the existence or exercise of any right of set-off by any
Lender Party, (F) the existence, validity or enforceability of any other
guaranty with respect to any of the Borrower Obligations, the liability of any
other Person in respect of any of the Borrower Obligations, or the release of
any such Person or any other guarantor of any of the Borrower Obligations, (g)
any act or omission of any Lender Party in connection with the administration
of any Loan Document, any Interest Rate Protection Agreement, or any of the
Borrower Obligations, (h) the bankruptcy, insolvency, reorganization or
receivership of, or any other proceeding for the relief of debtors commenced
by or against, any Person, (i) the disaffirmance or rejection, or the
purported disaffirmance or purported rejection, of any of the Borrower
Obligations, any Loan Document, any Interest Rate Protection Agreement, or any
agreement, instrument or document executed or delivered in connection
therewith, in any bankruptcy, insolvency, reorganization or receivership, or
any other proceeding for the relief of debtors, relating to any Person, (j)
any law, regulation or decree now or hereafter in effect that might in any
manner affect any of the terms or provisions of any Loan Document, any
Interest Rate Protection Agreement, or any agreement, instrument or document
executed or delivered in connection therewith or any of the Borrower
Obligations, or which might cause or permit to be invoked any alteration in
the time, amount, manner or payment or performance of any of the Borrower's
obligations and liabilities (including, without limitation, the Borrower
Obligations), (k) the merger or consolidation of the Borrower into or with any
Person, (L) the sale by the Borrower of all or any part of its assets, (M) the
fact that at any time and from time to time none of the Borrower Obligations
may be outstanding or owing to any Lender Party, (N) any amendment or
modification of, or supplement to, any Loan Document or any Interest Rate
Protection Agreement or (O) any other reason or circumstance that might
otherwise constitute a defense available to or a discharge of the Borrower in
respect of its obligations or liabilities (including, without limitation, the
Borrower Obligations) or of the Guarantor in respect of any of the Guarantor
Obligations (other than by the performance in full thereof).
 
  4. Representations and Warranties
 
  The Guarantor hereby makes the following representations and warranties to
the Administrative Agent on behalf of each Lender Party:
 
    (a) Existence and Power. The Guarantor is duly organized or formed and
  validly existing in good standing under the laws of the jurisdiction of its
  incorporation or formation, has all requisite power and authority to own
  its Property and to carry on its business as now conducted, and is in good
  standing and authorized to do business as a foreign corporation in each
  jurisdiction in which the nature of the business conducted therein or the
  Property owned therein makes such qualification necessary, except where
  such failure to qualify could not reasonably be expected to have a Material
  Adverse Effect.
 
    (b) Authority. The Guarantor has full legal power and authority to enter
  into, execute, deliver and perform the terms of the Loan Documents to which
  it is a party and the transactions contemplated thereby and to incur the
  obligations provided for therein, all of which have been duly authorized by
  all proper and necessary corporate or other applicable action and are in
  full compliance with its Certificate of Incorporation or By-Laws or its
  other organization documents.
 
 
                                       3

 
    (c) Binding Agreement. The Loan Documents to which the Guarantor is a
  party constitute the valid and legally binding obligations of the
  Guarantor, enforceable in accordance with its terms, except as such
  enforceability may be limited by applicable bankruptcy, insolvency,
  reorganization, moratorium, fraudulent conveyance or other similar laws
  affecting the enforcement of creditors' rights generally and except that
  the remedy of specific performance is within the discretion of the
  applicable court.
 
    (d) Required Consents. No consent, authorization or approval of, filing
  with, notice to, or exemption by, stockholders, any Governmental Authority
  or any other Person is required to authorize, or is required in connection
  with the execution, delivery and performance of the Loan Documents to which
  the Guarantor is a party and the transactions contemplated thereby, or is
  required as a condition to the validity or enforceability of such Loan
  Documents.
 
    (e) No Conflicting Agreements. The Guarantor is not in default under any
  mortgage, indenture, contract or agreement to which it is a party, or by
  which it or any of its Property is bound, the effect of which default could
  reasonably be expected to have a Material Adverse Effect. The execution,
  delivery or carrying out of the terms of the Loan Documents to which it is
  a party and the transactions contemplated hereby and thereby, will not
  constitute a default under, or result in the creation or imposition of, or
  obligation to create, any Lien upon any Property of the Guarantor or result
  in a breach of or require the mandatory repayment of or other acceleration
  of payment under or pursuant to the terms of any such mortgage, indenture,
  contract or agreement.
 
  5. Events of Default
 
  Each of the following shall constitute an "Event of Default" hereunder:
 
    (a) The Guarantor shall fail to observe or perform any term, covenant or
  agreement contained in Section 2 of this Guaranty; or

  covenant or agreement on its part to be performed or observed pursuant to
  this Guaranty and such failure shall have continued unremedied for a period
  of 30 days after the Guarantor shall become aware of such failure; or
 
    (c) Any representation or warranty of the Guarantor contained herein or
  in any certificate, report or notice delivered or to be delivered by the
  Guarantor pursuant hereto shall prove to have been incorrect or misleading
  in any material respect when made; or
 
    (d) This Guaranty shall cease to be in full force and effect or the
  Guarantor shall so assert or shall disavow any of its obligations
  hereunder; or
 
    (e) The occurrence of an "Event of Default" under and as defined in the
  Credit Agreement.
