                                PROMISSORY NOTE

$10,000,000.00                                                   August 21, 1995

         WHEREAS, KINETIC CONCEPTS, INC. ("Lender"), a Texas corporation, has
agreed to lend, and has lent, to JAMES R.  LEININGER ("Borrower") the principal
sum of $10,000,000.00 with interest to accrue on the unpaid principal balance
outstanding on such loan at the same rate of interest as would be available for
a "Eurodollar Loan" in a like amount made as of the date of this Note under
Borrower's existing credit facility with Texas Commerce Bank National
Association (the "Bank") evidenced by that one certain Promissory Note for
Prime Rate and Eurodollar Loans (the "Bank Note") dated June 30, 1995, executed
by Borrower and made payable to the order of the Bank (as the term "Eurodollar
Loan" is used and defined in the Bank Note), which rate of interest has been
determined by Lender and Borrower to be, and shall be conclusively deemed to be
7.9375% per annum;

         NOW, THEREFORE, FOR VALUE RECEIVED, Borrower agrees and promises to
pay to the order of Lender at its offices at 8023 Vantage Drive, San Antonio,
Texas  78230, the principal sum of TEN MILLION AND NO/100 DOLLARS
($10,000,000.00), or so much thereof as shall have been advanced hereunder, in
lawful money of the United States of America, together with interest on the
unpaid principal balance outstanding from time to time from the date hereof
until maturity at the rate of 7.9375% per annum.  Matured, unpaid amounts due
and owing hereunder shall accrue interest at the rate of twelve percent (12%)
per annum.

         Subject to the provisions hereof limiting interest to the maximum rate
of interest allowed by applicable law (the "Maximum Rate"), interest shall be
computed at a daily rate equal to 1/360th of the applicable rate of interest
per annum.

         Principal and interest hereunder shall be due and payable as follows:

         (1) Interest hereon shall be due and payable in yearly installments of
             all then accrued but unpaid interest on August 21, 1996 and August
             21, 1997 (the "Maturity Date"), at which later date the unpaid
             principal balance hereof, shall also be due and payable.

         (2) If, prior to the Maturity Date, Borrower disposes of any of the
             shares of stock of Lender owned by Borrower (other than any
             transfer of any such shares to a parent, sibling, spouse, or child
             of Borrower pursuant to any written option agreement existing on
             the date hereof), there





                                       1
   2





             shall be due and payable hereunder an amount equal to twenty-five
             percent (25%) of the net proceeds of any such disposition.

         All payments received hereunder shall be applied first to accrued and
unpaid interest, and then to the payment of the principal balance hereof.

         All or any portion of the principal of this note may be prepaid
without penalty at any time or times, and interest shall immediately cease on
the amount so prepaid.  All partial prepayments shall be applied to the
principal last maturing hereunder, without reducing the amount or extending the
time of payment of the remaining payments due hereunder.

         Upon the occurrence of any one of the following events (a "Default"),
then without notice or demand, unless otherwise specifically provided for in
this note or in any instrument or agreement executed in connection with this
note (the "Loan Documents"), the Lender may declare all outstanding principal
and all accrued and unpaid interest under this note immediately due and payable
together with all other sums owing by the Borrower under the Loan Documents:

         (1) Default in any payment of any principal or interest payable under
             this note when due if such default continues for a period of ten
             (10) days after Lender gives notice to Borrower of such default;
             or

         (2) Default under the terms of any of the Loan Documents if such
             default continues for a period of thirty (30) days after Lender
             gives notice to Borrower of such default.

         The Borrower agrees to pay all costs of the Lender in collecting any
sums payable by the Borrower hereunder and under the Loan Documents when such
costs are incurred, including reasonable attorney's fees, whether or not this
note has been accelerated or any other action has been instituted to enforce
this note.

         Unless otherwise specifically set forth in this note or the Loan
Documents, the Borrower, and each surety, endorser, guarantor and other person
liable upon this note, waives (i) all demands and presentments for payment,
(ii) all notices of non-payment, intention to accelerate maturity, acceleration
of maturity, protest and dishonor, and (iii) diligence in taking any action to
collect amounts hereunder and in the handling of any collateral securing this
note.

         The Borrower and the Lender intend that the loan evidenced by this
note (the "Loan") shall be in strict compliance with applicable usury laws.  If
at any time any interest contracted for, charged or received under this note or
otherwise in connection with the Loan would be usurious under applicable law,
then regardless of any provisions of this note or the Loan Documents or any
action or event (including, without limitation, prepayment of principal
hereunder or acceleration of maturity by the Lender) which may occur with
respect to this note or the Loan, it is





                                       2
   3




agreed that all sums that otherwise would be usurious shall be immediately
credited by the Lender as a payment of principal hereunder, or if this note has
already been paid, immediately refunded to the Borrower.  All compensation
which constitutes interest under applicable law in connection with the Loan
shall be amortized, prorated, allocated and spread over the full period of time
any indebtedness is owing by the Borrower under the Loan, to the greatest
extent permissible without exceeding the Maximum Rate in effect from time to
time during such period.

         This note and all of the Loan Documents shall be deemed contracts made
under the laws of the State of Texas and for all purposes shall be interpreted
under such laws.  In particular, the Lender and the Borrower agree that the
Indicated (weekly) Rate ceiling, as determined in accordance with Article
5069-1.04, as amended (Revised Civil Statutes of Texas), from time to time in
effect, shall constitute the Maximum Rate hereunder.  Provided, however, that
if United States federal law should permit the Lender to contract for, charge
or receive a greater rate of interest than the rate determined under Article
5069-1.04, then such federal law, from time to time in effect, shall determine
the Maximum Rate hereunder.

         In no event shall the provisions of Chapter 15, Article 5069 of the
Revised Civil Statutes of Texas (which regulates certain revolving loan
accounts and revolving tri-party accounts) apply to the Loan.

         This note is secured by a Stock Pledge Agreement of even date herewith
executed by Borrower covering certain shares of stock of Lender more fully
described therein.
