Dr. Leininger agrees for himself, that immediately after the Closing Time, the
KCI Percentages held by them will be that set forth in Schedule 1.08, and that

Public Offering pursuant to the Securities Act, no shares of Common Stock or of

Persons comprising the Fremont/KCI Group or the RCBA/KCI Group may be sold,
transferred, pledged, or hypothecated, directly or indirectly (a "Transfer"),
except as set forth in Section 2.02 hereof. Any attempted Transfer that is not
permitted by this Section 2 shall be deemed a violation and breach of this
Agreement that may be treated as null and void by the Shareholders and by KCI.
Any shares of Common Stock or of equity interests in the entities comprising the
controlling interests in the Persons comprising the Fremont/KCI Group or the
RCBA/KCI Group that are the subject of a Transfer permitted by this Section 2
shall remain subject to this Section 2. As a condition precedent to the
effectiveness of any Transfer to any person or entity that is not a party to
this Agreement, such transferee, for good and recognizable consideration, shall
agree in writing to become a party to this Agreement and to be bound by its
terms and provisions.
 
     2.02 Permitted Transfers.  Notwithstanding the foregoing, the following
Transfers will be permitted so long as the transferee, for good and recognizable
consideration, agrees in writing to become a party to this Agreement and to be
bound by its terms and provisions and so long as the Transfer complies with the
registration provisions (or exemptions therefrom) of all applicable federal and
state securities laws:
 
          (a) Transfers by gift or the laws of descent and distribution to any
     Affiliate of the transferor.
 
          (b) Sales by Fremont or any member of the Fremont/KCI Group to any
     other member of the Fremont/KCI Group.
 
          (c) Sales by RCBA or any member of the RCBA/KCI Group to any other
     member of the RCBA/ KCI Group.
 
          (d) Sales between Fremont or any member of the Fremont/KCI Group on
     the one hand and RCBA or any member of the RCBA/KCI Group on the other
     hand, or vice versa, so long as the seller has first offered the securities
     on the same price and terms, for at least thirty (30) days, to the member
     of its own Group.
 
          (e) Sales by Dr. Leininger of up to 10.5% of KCI's then outstanding
     Common Stock.
 
     2.03 Tag-Along Rights.  If, at any time after the restrictions of Section
2.01 expire, a Shareholder proposes to sell Common Stock for value (the
"Transferor") to any Person (other than a transferee in a Transfer permitted by
Section 2.02) in one transaction or a series of related transactions, then such
Transferor shall offer (the "Participation Offer") to include in the proposed
sale a number of shares of Common Stock designated by any of the other
Shareholders not to exceed, in respect of any such Shareholder, the number of
shares equal to the product of (i) the aggregate number of shares to be sold to
the proposed transferee and (ii) the Shareholder's respective KCI Percentage;
provided that if the consideration to be received includes any securities, only
Shareholders that are Accredited Investors (as defined below) shall be entitled
to include their shares in such sale (but, in such case, each Shareholder shall
be entitled to include in such sale a number of its shares, without duplication,
equal to the number of shares held by its Affiliates that are excluded from sale
by the operation of this proviso). The Transferor shall give written notice to
each Shareholder of the Participation Offer (the "Transferor's Notice") at least
twenty (20) days prior to the proposed sale. The Transferor's Notice shall
specify the proposed transferee, the number of shares to be sold to such
transferee, the amount and type of consideration to be received therefor, and
the place and date on which the sale is to be consummated. Each Shareholder that
wishes to include shares of Common Stock in the proposed sale in accordance with
the terms of this Section 2.03 shall so notify the Transferor not more than ten
(10) days after
 
                                      III-2
   3
 
the date of the Transferor's Notice. The Participation Offer shall be
conditioned upon the Transferor's sale of shares pursuant to the transactions
contemplated in the Transferor's Notice with the transferee named therein. If
any Shareholder accepts the Participation Offer, the Transferor shall reduce to
the extent necessary the number of shares it otherwise would have sold in the
proposed sale so as to permit other Shareholders that have accepted the
Participation Offer to sell the number of shares that they are entitled to sell
under this Section 2.03, and the Transferor and such other Shareholder or
Shareholders shall sell the number of shares specified in the Participation
Offer to the proposed transferee in accordance with the terms of such sale set
forth in the Transferor's Notice. For purposes of this Section 2.03, "Accredited
Investor" shall have the meaning set forth for such term in Regulation D.
Notwithstanding the foregoing, a Shareholder shall have the right to include
shares of Common Stock in the Transferor's sale under this Section 2.03 only if
such Shareholder holds, on the date he receives the Transferor's Notice, at
least ten percent (10%) of the issued and outstanding shares of Common Stock.
 
     2.04 Drag-Along Rights.
 
          (a) Notwithstanding any other provision in this Section 2, if, at any
     time after the restrictions of Section 2.01 expire, Fremont, RCBA, the
     Fremont/KCI Group, and the RCBA/KCI Group (collectively, the "Seller")
     propose to sell all (but not less than all) of the Common Stock they then
     hold to a third party or parties in which the Seller does not own, have any
     right to acquire, or propose to own or acquire, any interest (a "Third
     Party") pursuant to a Bona Fide Offer (as defined below), then the Seller
     shall have the right, subject to the provisions of this Section 2.04, to
     require Dr. Leininger (the "Co-Seller"), to include in such sale (a
     "Required Sale") all of the Common Stock held by the Co-Seller by
     delivering notice (the "Required Sale Notice") to the Co-Seller.
 
          (b) The Required Sale Notice shall set forth: (i) the date of such
     notice (the "Notice Date"), (ii) the name and address of the Third Party,
     (iii) the proposed amount of consideration to be paid per share for the
     Sale Shares, and the terms and conditions of payment offered by the Third
     Party in reasonable detail, together with written proposals or agreements,
     if any, with respect thereto, (iv) the aggregate number of Sale Shares, (v)
     confirmation that the Seller is selling one hundred percent (100%) of the
     aggregate number of shares of Common Shares then held by it to a Third
     Party, and (vi) the proposed date of the Required Sale (the "Required Sale
     Date"), which shall be not less than twenty (20) nor more than one hundred
     eighty (180) days after the date of the Notice Date.
 
          (c) The Co-Seller shall cooperate in good faith with the Seller in
     connection with consummating the Required Sale (including, without
     limitation, the giving of consents and the voting of any Common Stock held
     by the Co-Seller to approve such Required Sale). On the Required Sale Date,
     the Co-Seller shall deliver, free and clear of all liens, claims, or
     encumbrances, a certificate or certificates and/or other instrument or
     instruments for all of its Common Stock, duly endorsed and in proper form
     for transfer, with the signature guaranteed, to such Third Party in the
     manner and at the address indicated in the Required Sale Notice and the
     Seller shall cause the Co-Seller's share of the purchase price to be paid
     to the Co-Seller.
 
          (d) "Bona Fide Offer" shall mean an offer (whether in the form of a
     purchase of shares, merger, recapitalization, business combination, or
     otherwise) for Common Stock.
 
          (e) In the event of any Required Sale, if the Co-Seller holds options
     to purchase Common Stock, he must exercise or cancel all such stock options
     prior to or simultaneously with the consummation of the Required Sale. Any
     shares of Common Stock for which options are exercised must be included in
     the Required Sale.
 
          (f) Notwithstanding the foregoing, the Co-Seller shall not be required
     to sell his shares of Common Stock under this Section 2.04 if, on the date
     he receives the Required Sale Notice, he holds less than ten percent (10%)
     of the issued and outstanding shares of Common Stock.

SECTION 3.  Governance and Voting.
 
     3.01 The Shareholders agree that each shall take such steps as are required
to assure that after the Closing Time, and continuing until such time as the
Common Stock shall have been the subject of a Public Offering registered under
the Securities Act, the Board of Directors of KCI shall have at least eight (8)
members, two (2) of whom shall be persons designated by Fremont, two (2) of whom
shall be persons designated by RCBA, one (1) of whom shall be Dr. Leininger (so
long as he shall own at least fifteen percent (15%) of the outstanding equity of
KCI), one (1) of whom shall be Raymond R. Hannigan (provided, however, that if
Raymond R. Hannigan for any reason ceases to serve KCI as its chief executive
officer, then the successor chief executive officer shall be elected to serve as
director in Mr. Hannigan's place), and two (2) or more of whom shall be
independent outside directors, who shall not be affiliated with Fremont or RCBA
and who shall be designated by the unanimous vote of the Nominating Committee of
the Board of Directors of KCI, which shall comprise Dr. Leininger, one (1)
director designated by Fremont, and one (1) director designated by RCBA.
 
     3.02 Each of Fremont, RCBA and Dr. Leininger agrees that none of them shall
charge any management, monitoring, consulting or similar fees to KCI or their
Affiliates without the prior consent of the other two (which consent shall not
be unreasonably withheld). In the event Fremont or RCBA charge any such fees to
KCI or its Affiliates (i) the fees shall be of a type and amount customary
between financial buyers and companies that have been the subject of a leveraged
buyout and (ii) Dr. Leininger shall participate in such fees to the extent
equitable in consideration for any management, monitoring or consulting services
that he has provided to KCI or its Affiliates.
 
     3.03 After the Closing Time, and until such time as the Common Stock shall
have been the subject of a Public Offering registered under the Securities Act,
each of Fremont and RCBA shall have the following rights with respect to KCI:
(i) the right to inspect the books and records of KCI and (ii) the right to
inspect the properties and operations of KCI. The rights provided to Fremont and
RCBA in Section 3.01 above and in this Section 3.03 are intended to enable
Fremont and RCBA to be operated as a "venture capital operating company" within
the meaning of the regulations of the Department of Labor set forth in 29 CFR
Section 2510.3-101(d), and Section 3.01 above and this Section 3.03 shall be
interpreted accordingly.
 
SECTION 4.  Preemptive Rights.
 
     4.01 Grant of Preemptive Rights.  KCI will not issue or sell any capital
stock without first complying with this Section 4. KCI hereby grants to each of
the Shareholders the preemptive right to purchase up to that Shareholder's Pro
Rata Share (as defined below) of any capital stock that KCI may, from time to
time, propose to sell or issue. For purposes of this Section 4, a Shareholder's
"Pro Rata Share" shall mean the percentage of all outstanding fully diluted
capital stock of KCI owned by that Shareholder from time to time.
 
     4.02 Suspension of Preemptive Rights.  The preemptive rights granted in
Section 4.01 shall be suspended with respect to Dr. Leininger if, at the time of
the proposed issuance and sale of capital stock, the exercise of such right
would result in Fremont, RCBA, the Fremont/KCI Group, and the RCBA/KCI Group
collectively holding less than a majority of the issued and outstanding shares
of Common Stock after giving effect to such issuance and sale.
 
     4.03 Notice to Shareholders.  If KCI proposes to issue or sell any capital
stock, KCI shall provide each Shareholder with written notice of KCI's intention
(the "Notice of Issuance"). The Notice of Issuance shall describe the type of
capital stock to be issued or sold and the price and other terms upon which KCI
proposes to issue or to sell such capital stock.
 
     4.04 Exercise of Preemptive Rights.  Each Shareholder may exercise its
preemptive right under this Section 4, in whole or in part, by giving written
notice of its election to participate in the offering within twenty (20) days
after receipt of the Notice of Issuance. If a Shareholder fails fully to
exercise such preemptive right within such twenty (20) day period, KCI shall
have sixty (60) days in which the sell the capital stock described in the Notice
of Issuance that the Shareholder did not agree to purchase. In the event
 
                                      III-4
   5
 
that KCI does not sell such capital stock within such sixty (60) day period, KCI
thereafter will not issue or sell such capital stock without again complying
with this Section 4.
 
     4.05 Exceptions.  Notwithstanding the foregoing, the preemptive rights
granted in Section 4.01 will not apply to (i) any issuance of capital stock as a
dividend or stock split in respect of outstanding capital stock or (ii) any
issuance of capital stock in an underwritten public offering.
 
SECTION 5.  Registration Rights.
 
     5.01 Demand Registration.
 
          (a) At any time after the fifth anniversary of this Agreement, if
     there has not been a Public Offering by such date, each of the Shareholders
     may make one (1) written request to KCI for registration of at least
     thirty-three percent (33%) of the shares of Common Stock then held by such
     Shareholder under Form S-3 (or such other appropriate or successor form if
     Form S-3 is not available) and in accordance with the provisions of Rule
     415 promulgated under the Securities Act (a "Demand Registration"). In
     addition to that right to request a Demand Registration, each Shareholder
     shall have the right to request an additional Demand Registration of at
     least thirty-three percent (33%) of the shares of Common Stock then held by
     such Shareholder at any time after one (1) year, but before three (3)
     years, following the completion of a Public Offering.
 
          (b) A registration will not count as a Demand Registration unless the
     Shareholder is able to register and sell at least seventy-five percent
     (75%) of the shares requested to be included in such registration;
     provided, however, that if the Shareholder is able to register and sell
     less than such stated percentage, the Shareholder shall be entitled to
     invoke this provision to request a subsequent Demand Registration on only
     one additional occasion.
 
          (c) KCI may include in any Demand Registration any of its securities
     to be registered for offering and sale on behalf of KCI.
 
          (d) If a Demand Registration is an underwritten registration and the
     managing underwriters advise KCI in writing that, in their opinion, the
     number of securities in such offering exceeds the number that can be sold
     in an orderly manner within a price range acceptable to the Shareholder and
     to KCI, then the number of such shares that the managing underwriters
     believe that may be sold in such offering shall be allocated first to the
     Shareholder's shares for inclusion in the registration statement, second to
     the shares of any Piggyback Shareholder (as defined in Section 5.02(a)),
     then to the KCI shares.
 
          (e) If a Demand Registration is an underwritten offering, the
     investment bankers and managers for the offering will be selected by the
     Shareholder, subject to the approval of KCI, which will not be unreasonably
     withheld.
 
          (f) KCI shall pay the expenses described in Section 5.06 for any
     registration pursuant to this Section 5.01.
 
     5.02 Piggyback Registration Rights.
 
          (a) If at any time KCI shall determine to proceed with the preparation
     and filing of a registration statement (other than a registration statement
     on Form S-4, Form S-8, or other limited purpose form) under the Securities
     Act in connection with KCI's or another securityholder's proposed offer and
     sale of Common Stock or equity securities convertible into Common Stock,
     KCI will give written notice of its determination to the Shareholders at
     least twenty (20) days prior to filing the registration statement. Upon the
     written request from a Shareholder given within ten (10) days after receipt
     of any such notice from KCI, KCI will include the number of shares
     requested by the Shareholder in such registration statement ("Piggyback
     Registration"). Notwithstanding anything in this Agreement to the contrary,
     if a Shareholder (a "Piggyback Shareholder") makes a request for Piggyback
     Registration in a registration statement filed pursuant to another
     Shareholder's request for a Demand Registration under Section 5.01, and the
     Piggyback Shareholder is able to register and sell at least seventy-five
     percent (75%) of the
 
                                      III-5
   6
 
     shares requested to be included in the registration, such request shall be
     deemed to satisfy the Piggyback Shareholder's right to request a Demand
     Registration under Section 5.01.
 
          (b) If a Piggyback Registration is an underwritten primary
     registration on behalf of KCI and the managing underwriters advise KCI in
     writing that, in their opinion, the number of total securities to be
     registered in such offering exceeds the number that can be sold in an
     orderly manner within a price range acceptable to KCI, then the number of
     securities that the managing underwriter believes may be sold in such
     offering shall be allocated first to the shares being offered by KCI for
     inclusion in the registration statement, then to the shares of Shareholders
     submitted for registration, pro rata among the Shareholders in accordance
     with the number of shares they then hold.
 
          (c) If a Piggyback Registration is an underwritten secondary
     registration on behalf of the shareholders of KCI's securities and the
     managing underwriters advise KCI in writing that, in their opinion, the
     number of total securities to be registered in such offering exceeds the
     number that can be sold in an orderly manner within a price range
     acceptable to the shareholders initially requesting such registration, KCI
     will include in such registration the securities being requested to be
     included therein by the holders initially requesting such registration and
     the shares of the Shareholders that requested Piggyback Registration, pro
     rata among the holders of such securities on the basis of the number of
     shares owned by each such shareholder.
 
          (d) KCI shall pay the expenses described in Section 5.06 for
     registration statements filed pursuant to this Section 5.02.
 
     5.03 Registration Procedures.  Whenever a Shareholder has requested that
KCI, pursuant to the provisions of Section 5.01 or Section 5.02, effect the
registration of Common Stock under the Securities Act, KCI will:
 
          (a) as soon as reasonably practicable, prepare and file with the SEC a
     registration statement with respect to such securities and use its best
     efforts to cause such registration statement to become and remain effective
     for such period as may be reasonably necessary to effect the sale of such
     securities (the "Effective Period");
 
          (b) as soon as reasonably practicable, prepare and file with the SEC
     such amendments to such registration statement and supplements to the
     prospectus contained therein as may be necessary to keep such registration
     statement effective for the Effective Period as may be reasonably necessary
     to effect the sale of such securities;
 
          (c) furnish to the Shareholder and to the underwriters for the
     securities being registered such reasonable number of copies of the
     registration statement, preliminary prospectus, final prospectus, and such
     other documents as the Shareholder and such underwriters may reasonably
     request in order to facilitate the public offering of such securities;
 
          (d) use its best efforts to register or qualify the Common Stock
     covered by such registration statement under such state securities or blue
     sky laws of such jurisdictions as the Shareholder may reasonably request in
     writing within ten (10) days following the original filing of such
     registration statement, except that KCI shall not for any purpose be
     required to execute a general consent to service of process or to qualify
     to do business as a foreign corporation in any jurisdiction wherein it is
     not so qualified or subject itself to taxation in a jurisdiction where it
     had not previously been subject to taxation or take any other action that
     would subject KCI to service of process in a lawsuit other than one arising
     out of the registration of the Common Stock;
 
          (e) cause all such registered shares of Common Stock to be listed on
     an exchange or NASDAQ by filing a subsequent listing application;
 
          (f) notify the Shareholder, promptly after it shall receive notice
     thereof, of the time when such registration statement has become effective
     or a supplement to any prospectus forming a part of such registration
     statement has been filed;
 
                                      III-6
   7
 
          (g) notify the Shareholder promptly of any request by the SEC for the
     amending or supplementing of such registration statement or prospectus or
     for additional information;
 
          (h) prepare and promptly file with the SEC and promptly notify the
     Shareholder of the filing of such amendment or supplement to such
     registration statement or prospectus as may be necessary to correct any
     statements or omissions if, at any time when a prospectus relating to such
     securities is required to be delivered under the Securities Act, any event
     shall have occurred as the result of which any such prospectus or any other
     prospectus as then in effect would include an untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein, in light of the circumstances in which they were made,
     not misleading; and
 
          (i) advise the Shareholder, promptly after it shall receive notice or
     obtain knowledge thereof, of the issuance of any stop order by the SEC
     suspending the effectiveness of such registration statement or the
     initiation or threatening of any proceeding for that purpose and promptly
     use its best efforts to prevent the issuance of any stop order or to obtain
     its withdrawal if such stop order should be issued.
 
     5.04 Underwriting.  A Shareholder may not participate in any registration
hereunder unless such Shareholder (a) agrees to sell its shares of Common Stock
on the basis provided in the underwriting arrangements, if any, and (b)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements, and other documents reasonably required under the terms
of such underwriting arrangements, if any, and these registration rights.
 
     5.05 Holdback Agreements.  Each Shareholder agrees not to effect any public
sale or distribution of Common Stock or any securities convertible into or
exchangeable or exercisable for Common Stock, including a sale pursuant to Rule
144 under the Securities Act, during the fourteen (14) days prior to, and during
a period of up to one hundred eighty (180) days beginning on and following the
effective date of any registration statement filed by KCI pursuant to this
Section 5 (except as part of such registration), if and to the extent reasonably
requested by the managing underwriter of the offering.
 
     5.06 Expenses.  With respect to any registration requested pursuant to
Section 5.01 hereof and with respect to an inclusion of a Shareholder's shares
of Common Stock in a registration statement pursuant to Section 5.02 hereof, all
fees, costs, and expenses of such registration, inclusion, and public offering,
including, without limitation, all registration, filing, and listing fees,
printing expenses, fees and disbursements of legal counsel and accountants for
KCI, and all legal fees and disbursements and other expenses of complying with
state securities or blue sky laws of any jurisdictions in which the securities
to be offered are to be registered and qualified, shall be borne by KCI;
provided, however, that each Shareholder shall bear its own attorney fees and
the underwriting commissions and registration fees with respect to the sale of
its shares of Common Stock.
 
     5.07 Indemnification.
 
          (a) KCI will indemnify and hold harmless each Shareholder and any
     underwriter (as defined in the Securities Act) for a Shareholder and each
     person, if any, who controls such Shareholder or underwriter within the
     meaning of the Securities Act, from and against and will reimburse the
     Shareholder and each such underwriter and controlling person with respect
     to, any and all loss, damage, liability, cost, and expense to which the
     Shareholder or any such underwriter or controlling person may become
     subject under the Securities Act or otherwise, insofar as such losses,
     damages, liabilities, costs, or expenses are caused by any untrue statement
     or alleged untrue statement of any material fact contained in such
     registration statement, any prospectus contained therein, or any amendment
     or supplement thereto or arise out of or are based upon the omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein, in light of the
     circumstances in which they were made, not misleading; provided, however,
     that KCI will not be liable in any such case to the extent that any such
     loss, damage, liability, cost, or expense arises out of or is based upon an
     untrue statement or alleged untrue statement or omission or alleged
     omission so made in conformity with information furnished in writing by a
     Shareholder, such underwriter, or such controlling person specifically for
     use in
 
                                      III-7
   8
 
     the preparation thereof. KCI will not be subject to any liability for any
     settlement made without its consent, which consent shall not be
     unreasonably withheld.
 
          (b) Each Shareholder will indemnify and hold harmless KCI, its
     directors and officers, any controlling person, and any underwriter thereof
     from and against, and will reimburse KCI, its directors and officers, any
     controlling person, and any underwriter thereof with respect to, any and
     all loss, damage, liability, cost, or expense to which KCI or any
     controlling person and/or any underwriter thereof may become subject under
     the Securities Act or otherwise, insofar as such losses, damages,
     liabilities, costs, or expenses are caused by any untrue statement or
     alleged untrue statement of any material fact contained in such
     registration statement, any prospectus contained therein, or any amendment
     or supplement thereto or arise out of or are based upon the omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein, in light of the
     circumstances in which they were made, not misleading, in each case to the
     extent, but only to the extent, that such untrue statement or alleged
     untrue statement or omission or alleged omission was so made in reliance
     upon and in conformity with information furnished in writing by or on
     behalf of the Shareholder specifically for use in the preparation thereof.
     A Shareholder will not be subject to any liability for any settlement made
     without its consent, which consent shall not be unreasonably withheld.
 
          (c) Promptly after receipt by an indemnified party pursuant to the
     provisions of paragraph (a) or (b) of this Section 5.07 of notice of the
     commencement of any action involving the subject matter of the foregoing
     indemnity provisions, such indemnified party will, if a claim thereof is to
     be made against the indemnifying party pursuant to the provisions of said
     paragraph (a) or (b), promptly notify the indemnifying party of the
     commencement thereof; but the omission to so notify the indemnifying party
     will not relieve it from any liability that it may have to any indemnified
     party otherwise than hereunder, except to the extent that such omission
     materially and adversely affects the indemnifying party's ability to defend
     against or compromise such claim. In case such action is brought against
     any indemnified party and it notifies the indemnifying party of the
     commencement thereof, the indemnifying party shall have the right to
     participate in and, to the extent that it may wish, jointly with any other
     indemnifying party similarly notified, to assume the defense thereof, with
     counsel satisfactory to such indemnified party; provided, however, that if
     the defendants in any action include both the indemnified party and the
     indemnifying party and there are legal defenses available to the
     indemnified party and/or other indemnified parties that are different from
     or in addition to those available to the indemnifying party or if there is
     a conflict of interest that would prevent counsel for the indemnifying
     party from also representing the indemnified party, the indemnified party
     or parties shall have the right to select separate counsel to participate
     in the defense of such action on behalf of such indemnified party or
     parties. After notice from the indemnifying party to an indemnified party
     of its election so to assume the defense thereof, the indemnifying party
     will not be liable to such indemnified party pursuant to the provisions of
     said paragraph (a) or (b) for any legal or other expense subsequently
     incurred by such indemnified party in connection with the defense thereof
     other than costs of investigation, unless (i) the indemnified party shall
     have employed counsel in accordance with the provisions of the preceding
     sentence, (ii) the indemnifying party shall not have employed counsel
     satisfactory to the indemnified party to represent the indemnified party
     within a reasonable time after the notice of the commencement of the
     action, or (iii) the indemnifying party has authorized the employment of
     counsel for the indemnified party at the expense of the indemnifying party.
 
          (d) If for any reason the foregoing indemnification is unavailable or
     is insufficient to hold harmless an indemnified party, then the
     indemnifying party shall contribute to the amount paid or payable by the
     indemnified party as a result of such losses, claims, damages, liabilities,
     or expenses in such proportion as is appropriate to reflect the relative
     fault of the indemnifying party on the one hand and the indemnified party
     on the other hand in connection with the statement or omission that
     resulted in the losses, claims, damages, liabilities, or expenses, as well
     as any other relevant equitable considerations. No person guilty of
     fraudulent misrepresentations (within the meaning of Section 11(f) of the
     Securities Act) shall be entitled to contribution from any person who was
     not guilty of such fraudulent misrepresentation.

SECTION 6.  Liabilities and Indemnification.
 
     6.01 Unless otherwise expressly assumed in writing by Fremont, the
Fremont/KCI Group, RCBA, the RCBA/KCI Group, or Dr. Leininger:
 
          (a) none of them shall be liable to any third parties for any actions,
     commitments, or debts of any other as a shareholder of KCI; and
 
          (b) each of them shall take all reasonable steps to negotiate and
     preclude exposing any of the other of them to any such liability to any
     third party.
 
     6.02 To the extent any of Fremont, the Fremont/KCI Group, RCBA, the
RCBA/KCI Group, or Dr. Leininger is presented with a demand or made party to an
adjudication by a third party asserting their potential liability as a
shareholder of KCI for any acts or omissions by any other party or parties to
this Agreement, they shall notify the other party or parties in writing
promptly, and upon the receipt of such notice the notified party or parties will
assume the responsibility for the defense, resolution, and/or satisfaction of
the claim and in all respects indemnify the party that is faced with such a
claim to the full extent of that party's costs and ultimate liabilities, if any.
 
SECTION 7.  Miscellaneous.
 
     7.01 Notices.  Except as otherwise expressly provided in this Agreement,
all notices, requests, and other communications to any party hereunder shall be
in writing (including a facsimile or similar writing) and shall be given to such
party at the address or facsimile number specified for such party on Schedule
7.01 hereto or as such party shall hereafter specify for that purpose by notice
to the other parties. Each such notice, request, or other communication shall be
effective (i) if given by facsimile, at the time such facsimile is transmitted
and the appropriate confirmation is received (or, if such time is not during a
business day, at the beginning of the next such business day), (ii) if given by
mail, three business days (or, if to an address outside the United States, seven
calendar days) after such communication is deposited in the mails with
first-class postage prepaid, addressed as aforesaid, or (iii) if given by any
other means, when delivered at the address specified pursuant to this Section
7.01.
 
     7.02 No Third Party Beneficiaries.  This Agreement is not intended to
confer any rights or remedies hereunder upon, and shall not be enforceable by,
any Person other than the parties hereto.
 
     7.03 Waiver.  No failure by any party to insist upon the strict performance
of any covenant, agreement, term, or condition of this Agreement or to exercise
any right or remedy consequent upon a breach of such or any other covenant,
agreement, term, or condition shall operate as a waiver of such or any other
covenant, agreement, term, or condition of this Agreement. Any Person by notice
given in accordance with Section 7.01 may, but shall not be under any obligation
to, waive any of its rights or conditions to its obligations hereunder, or any
duty, obligation, or covenant of any other Person. No waiver shall affect or
alter the remainder of this Agreement, but each and every covenant, agreement,
term, and condition hereof shall continue in full force and effect with respect
to any other then existing or subsequent breach. The rights and remedies
provided by this Agreement are cumulative, and the exercise of any one right or
remedy by any party shall not preclude or waive its right to exercise any or all
other rights or remedies.
 
     7.04 Integration.  This Agreement constitutes the entire agreement among
the parties hereto and thereto pertaining to the subject matter hereof and
thereof and supersedes all prior agreements and understandings of the parties in
connection herewith and therewith, and no covenant, representation, or condition
not expressed in this Agreement, the confidentiality agreements between Fremont,
RCBA, and KCI, or any other such agreement shall affect, or be effective to
interpret, change, or restrict, the express provisions of this Agreement.
 
     7.05 Dispute Resolution.  Any controversy, claim or dispute between Dr.
Leininger and any other party to this Agreement, arising out of or relating to
this Agreement or any breach thereof, including any dispute concerning the scope
of this Section 7.05, shall be resolved exclusively in a California court of law
in a proceeding conducted without a jury, each party hereto expressly waiving
their right to a trial by jury.
 
                                      III-9

     7.06 Headings.  The titles of the Sections of this Agreement are for
convenience only and shall not be interpreted to limit or amplify the provisions
of this Agreement.
 
     7.07 Counterparts.  This Agreement may be executed in multiple
counterparts, each of which shall be deemed an original and all of which, taken
together, shall constitute one and the same instrument, which may be
sufficiently evidenced by one counterpart.
 
     7.08 Severability.  Each provision of this Agreement shall be considered
separable and if for any reason any provision or provisions hereof are
determined to be invalid and contrary to any existing of future law, such
invalidity shall not impair the operation of or affect those portions of this
Agreement that are valid.
 
     7.09 Applicable Law.  This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware without giving effect to the
conflicts of law principles thereof.
 
     7.10 Non-Assignability.  All of the rights and obligations of the parties
to this Agreement are intended to be exercisable and fulfilled by the parties
themselves, as presently constituted. None of those rights or obligations may be
assigned, assumed, or transferred without the written informed consent of the
counterparties.
 
     IN WITNESS WHEREOF, this Agreement has been duly executed by the parties as
of the day and year first above written.
