<PAGE>   18
                                    INDEMNITY

         13.1 Indemnity. Biosite shall defend, indemnify and hold KDK, its
Affiliates and/or its Agencies harmless from all costs, damages and expenses
(including reasonable attorneys' fees) that KDK may suffer as a result of any
claims or judgments in favor of any Third Party for bodily injury, property
damage, or any other damage or injury caused or alleged to have been caused by
the defective Product (including without limitation design defects,
manufacturing defects and warning defects) except to the extent that any such
damage is attributable to the gross negligence or willful misconduct of KDK.
Each party shall indemnify, defend and hold harmless the other party, its
directors, officers, employees and agents from all losses, liabilities, damages
and expenses (including reasonable attorney's fees and cost) that they may
suffer as a result of any claims, demands, actions or other proceedings made or
instituted by any Third Party against any of them and arising out of or relating
to (a) any breach of the Agreement by the indemnifying party, (b) any negligence
or intentional act or omission by or on behalf of the indemnifying party in the
performance of its activities contemplated by the Agreement, (c) any
misrepresentation or misstatements by KDK or Biosite, in each case other than
those certain losses, liabilities, damages and expenses arising out of the gross
negligence or willful misconduct of the indemnified party.

         13.2 Procedure. A party (the "Indemnitee") that intends to claim
indemnification under this Article 13 shall promptly notify the other party (the
"Indemnitor") of any claim, demand, action or other proceeding with respect to
which the Indemnitee intends to claim such indemnification. The Indemnitor shall
have the right to participate in, and, to the extent the Indemnitor so desires,
jointly with any other Indemnitor similarly notices, to assume the defense
thereof with counsel selected by the Indemnitor; provided, however, that an
Indemnitee shall have the right to retain its own counsel, with the fees and
expenses to be paid by the Indemnitor, if representation of the Indemnitee by
the counsel retained by the Indemnitor would be inappropriate due to actual or
potential differing interests between such Indemnitee and any other party
represented by such counsel in such proceedings. The indemnity obligations under
this Article 13 shall not apply to amounts paid in settlement of any loss,
liability, damage or other expense if such settlement is effected without the
consent of the Indemnitor, which consent shall not be withheld unreasonably. The
failure to deliver notice to the Indemnitor within a reasonable time at the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such Indemnitor of any liability to the Indemnitee under
this Article 13, but the omission so to deliver notice to the Indemnitor will
not relieve it of any liability that it may have to any Indemnitee otherwise
than under this Article 13. The Indemnitor may not settle the action or
otherwise consent to an

                                      -18-
<PAGE>   19
adverse judgment in such action that diminishes the rights or interests of the
Indemnitee without the express written consent of the Indemnitee. The
Indemnitee, its employees and agents, shall cooperate fully with the Indemnitor
and its legal representatives in the investigation of any action, claim or
liability covered by this indemnification.

         13.3 Insurance. Biosite shall maintain, through self-insurance or
otherwise, such insurance and products liability insurance against claims
regarding the development and manufacture of the Testing Device by Biosite under
the Agreement, in such amounts as it customarily maintains for similar
activities. Biosite shall maintain such insurance during the term of the
Agreement and thereafter for so long as it maintains insurance for itself
covering similar activities.

prepaid (where applicable), addressed to such other party at its address
indicated below, or to such other address as the addressee shall have last

reasonable control of the affected party including fire, floods, embargoes, war,
acts of war (whether war be declared or not), insurrections, riots, civil

intend to violate any public policy, statutory or common laws, rules,
regulations, treaty or decision of any government agency or executive body
thereof of any country or community or association of countries. Should one or
more provisions of the Agreement be or become invalid, the parties shall
substitute, by mutual consent, valid provisions for such invalid provisions
which valid provisions in their economic effect are sufficiently similar to the
invalid provisions that it can be reasonably assumed that the parties would have
entered into the Agreement with such provisions. In case such provisions cannot
be agreed upon, the invalidity of one or several provisions of the Agreement
shall not affect the validity of the Agreement as a whole, unless the invalid
provisions are of such essential importance to the Agreement that it is to be
reasonably assumed that the parties would not have entered into the Agreement
without the invalid provisions.

         14.5 Governing Law. The Agreement shall be governed by and construed in
accordance with the laws of the State of California, U.S.A., without regard to
the conflicts of law principles thereof, and shall not be governed by the United

initiated by either party relating to, arising out of or resulting from the
Agreement, or the performance by either party of its obligations hereunder,
whether before or after termination of the Agreement, shall be finally resolved
by binding arbitration pursuant to the Japan-American Trade Arbitration
Agreement of September 16, 1952. Whenever a party shall decide to institute
arbitration proceedings, it shall give written notice to that effect to the
other party. If initiated by Biosite, such arbitration hereunder shall be
conducted under the Commercial Arbitration Rules of the Japan Commercial
Arbitration Association, and any applicable procedural laws of Japan, and shall
be held in Osaka, Japan. If initiated by KDK,

                                      -20-

         14.7 U.S. Export Laws and Regulations. Each party hereby acknowledges
that the marketing rights and information disclosure requirements of the
Agreement are subject to the laws and regulations of the United States relating
to the export of products and technical information. Without limitation, each
party shall comply with all such laws and regulations.

of the parties with respect to the subject matter hereof. All express or implied
agreements and understandings, either oral or written, heretofore made are
expressly superseded by the Agreement. The Agreement may be amended, or any term
hereof modified, only by a written instrument duly executed by both parties.

         14.9 Headings. The captions to the several Articles and Sections hereof
are not a part of the Agreement, but are merely guides or labels to assist in
locating and reading the several Articles and Sections hereof.

parties shall not constitute a partnership, joint venture or agency. Neither

other, without the prior consent of the party to do so.

govern and control any translations of the Agreement into any other language.

         14.12 Waiver. The waiver by either party of any right hereunder or the
failure to perform or of a breach by the other party shall not be deemed a
waiver of any other right hereunder or of any other breach or failure by said
other party whether of a similar nature or otherwise.

         14.13 Counterparts. The Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which

monoclonal and polyclonal antibodies for the quantitative detection of three
cardiac markers in 10 minutes.  The assay is performed in a wholly contained
disposable device which is analyzed using a portable instrument.

2) Procedure:           1.  Label device.

                        2.  Add an unmeasured amount of anticoagulated whole
                            blood, plasma or serum to sample port.

                        3.  Input specimen ID. Insert device into instrument for
                            incubation, assay validation and quantification of
                            results.  Instrument will determine when assay is
                            finished via internal control values.  Any devices
                            run simultaneously can be read after 1st device is
