cooperate with such laboratory in performing such testing by making available
such documentation, facilities, reagents, and other materials as the laboratory
may request of the Party. The Parties agree that the written decision of such
testing laboratory shall be accepted as final and binding. In case the
laboratory test proves that the relevant Product did not comply with the
Specifications at the time of delivery by Denka Seiken to the carrier, then all
cost and expense of transportation, shipping, insurance, and the like related to
the testing shall be paid by Denka Seiken.

CONFIDENTIALITY

6.1    Confidentiality Obligations. Each Party agrees that, for the Term and for
five (5) years thereafter, such Party will keep, and will ensure that its
officers, directors, employees, and agents keep, strictly confidential and will
not publish or otherwise disclose and will not use for any purpose except as
permitted under this Agreement any Confidential Information furnished to it by
the other Party pursuant to this Agreement (including, without limitation,
know-how of the disclosing Party); provided that, if any such Confidential
Information is disclosed orally, the disclosing Party shall provide the
receiving Party a written summary of such Confidential Information within thirty
(30) days after such initial oral disclosure. The foregoing confidentiality
obligations will not apply to any information to the extent that it can be
established by such receiving Party that such information:

(a)    was already known to the receiving Party as evidenced by its written
records, other than under an obligation of confidentiality, at the time of
disclosure;

(b)    was generally available to the public or was otherwise part of the public
domain at the time of its disclosure to the receiving Party;

(c)    became generally available to the public or otherwise becomes part of the

the receiving Party in breach of this Agreement;

(d)    was subsequently lawfully disclosed to the receiving Party by a Third
Party other than in contravention of a confidentiality obligation of such Third
Party to the disclosing Party; or

(e)    was developed or discovered by employees of the receiving Party or its
affiliates who had no access to the Confidential Information of the disclosing
Party, as evidenced by the receiving Party’s written records.

6.2    Permitted Disclosures. Subject to the prior written consent of the other
Party, which consent will not be unreasonably withheld or delayed, each Party
may disclose the other’s Confidential Information to the extent such disclosure
is reasonably necessary in filing or prosecuting patent applications,
prosecuting or defending litigation, advising investors and the investment
community of the results of the activities under this Agreement , complying with
applicable governmental regulations or court orders, or otherwise in performing
its obligations or exercising its rights under this Agreement. If a Party is
required to make any such disclosure of the other Party’s Confidential
Information, it will give reasonable advance notice to that other Party of such
disclosure requirement, will cooperate with the other Party in its efforts to
secure confidential treatment of such Confidential Information prior to its
disclosure, and, except to the extent inappropriate in the case of patent
applications, will use all reasonable efforts to secure confidential treatment
of such information prior to its disclosure (whether through protective orders
or confidentiality agreements or otherwise).

--------------------------------------------------------------------------------

 

6.3    Disclosure of Agreement Terms. Except to the extent required by law or as
otherwise permitted in accordance with this Section 6.3, neither Party shall
make any public announcements concerning this Agreement or publish its terms
without the prior written consent of the other Party. Notwithstanding the
foregoing, either Party shall have the right to disclose this Agreement or its
terms to the extent disclosure is required under applicable law, regulation, or
valid order of a court or other governmental body to which such Party is
subject, provided that such Party shall in good faith seek to minimize the
extent of such disclosure through a protective order or confidential treatment
order and, provided further, that such Party shall, as soon as practicable after
becoming aware of the need for such disclosure, give written notice to the other
Party of the need for such disclosure so that such other Party may (if it elects
and at its own cost) also seek a protective order or other confidential
treatment.

participate in such defense) at its own expense through attorneys reasonably
acceptable to the indemnified party, but may not, without the prior written
consent of the indemnified party agree to (i) any injunctive relief or
restrictions affecting the indemnified party or (ii) any settlement which would
adversely affect the business or operations of the indemnified party, including,
without limitation, any admission of wrongdoing or fault by the indemnified
party. If the indemnifying party does not elect to defend such claim or suit
within ten (10) days after having received written notice thereof or fails to
prosecute its defense diligently, the indemnified party may at its sole
discretion defend against such claim or suit at the indemnifying party’s
expense. The indemnified party may thereafter elect to settle such claim or suit
or otherwise enter into a compromise with the claimant.

indemnified party in any such claim or suit, whether or not Denka Seiken and/or
diaDexus conduct the defense of such claim or suit, the indemnifying party shall
indemnify and hold harmless the indemnified party for all such damages and/or
costs. All other costs and/or fees which result from the assertion of any such
claim or suit, including but not limited to attorneys fees, incurred by the
indemnified party in defense of any such claim or suit shall be reimbursed to
the indemnified party by the indemnifying party.

EXPLOITATION OF THE OTHER PARTY’S INTELLECTUAL PROPERTY RIGHTS OR BREACH OF THE

Agreement shall be considered a breach of this Agreement if and to the extent
caused by occurrences beyond the reasonable control of the Party affected and
without such Party’s fault or negligence, including but not limited to acts of
God, embargoes, governmental restrictions, strikes or other concerted acts of
workers, fire, earthquake, flood, tornadoes, explosion, riots, wars, civil

or failure in performance by a Party under this Section 10.8 continues longer

accordance with the terms and conditions of Section 9.2.

10.9    Waiver. A waiver by any Party of any of the terms and conditions of this

this Agreement will be cumulative and none of them will be in limitation of any
other remedy, right, undertaking, obligation, or agreement of either Party.

be found by a court to be void, invalid, or unenforceable, the same shall be
reformed to comply with applicable law or stricken if not so conformable, so as
not to affect the validity or enforceability of this Agreement; provided that no
such reformation or striking shall be effective if the result materially changes
the economic benefit of this Agreement to either Party. In the event that any
provision of this Agreement becomes or is declared by a court of competent
jurisdiction to be void, invalid, or unenforceable, and reformation or striking
of such provision would materially change the economic benefit of this Agreement
to either Party, the Parties shall modify such provision in accordance with
Section 10.3 to obtain a legal, valid, and enforceable provision and provide an
economic benefit to the Parties that most nearly effects their intent on
entering into this Agreement.

States and foreign laws, regulations, and orders as may be applicable, including
obtaining all necessary approvals required by the applicable agencies of the
governments of the United States and foreign jurisdictions.

10.12    No Third Party Beneficiaries. This Agreement is neither expressly nor
impliedly made for the benefit of any party other than those executing it.

10.13    Counterparts. This Agreement may be executed simultaneously in any
number of counterparts, any one of which need not contain the signature of more
