shall be owned jointly by IsoTis and AlloSource.

the Licensed Intellectual Property. If necessary, AlloSource shall have the
right to join IsoTis in any such suit as a party and to seek damages for past
infringement. IsoTis agrees to cooperate with AlloSource in the prosecution of

a result of such cooperation. AlloSource shall have the right, in its sole
discretion, to make all decisions regarding prosecution or settlement of any
such suit.

PARTY CLAIM"), the Party first having notice shall promptly notify the other
Party in writing. The notice shall set forth the facts of the Third Party Claim
in reasonable detail. The Parties shall promptly meet and confer in good faith

      8.1 The Parties have provided to each other prior to the Effective Date,
and in connection with this Agreement may in the future provide to each other,
Confidential Information.

      8.2 The receiving Party shall maintain the Confidential Information of the
disclosing Party in confidence, shall not disclose such Confidential Information
to any Third Party, and shall not use such Confidential Information for any
purpose except as expressly permitted under the terms and conditions of this
Agreement. Notwithstanding the previous sentence, the receiving Party may
disclose the Confidential Information of the disclosing Party to its employees,
agents, consultants, and professional, scientific, medical, and legal advisors
who have a reasonable need to know such Confidential Information to carry out
such Party's obligations or to exercise such Party's rights under this
Agreement; provided that any such person to whom disclosure is made is bound by
written obligations of non-disclosure and non- use no less restrictive then
those set forth herein. The receiving Party shall take the same degree of care
that such Party uses to protect its own confidential and proprietary information
of a similar nature and importance, but in no event shall such care be less than
reasonable care.

      8.3 The obligations of non-disclosure and non-use under Section 8.2 will
not apply as to particular Confidential Information of a disclosing Party to the
extent that such Confidential Information: (i) is at the time of receipt, or
thereafter becomes, through no fault of the receiving Party, published or
publicly known or available; (ii) is known by the receiving Party or its
Affiliates at the time of receiving such information, as evidenced by prior
written records; (iii) is hereafter furnished to the receiving Party or its
Affiliates by a Third Party without breach of a duty to the disclosing Party; or
(iv) is independently discovered or developed by the receiving Party or its
Affiliates without use of, application of, access to, or reference to
Confidential Information of the disclosing Party, as evidenced by prior written
records.

<PAGE>

      8.4 Disclosure of Confidential Information shall not be precluded if such
disclosure (i) is in response to a valid order of a court or other Government
Authority of competent jurisdiction or (ii) is required by applicable law;
provided, however, that the receiving Party shall first have given reasonable
prior written notice to the disclosing Party pursuant to Section 10.8, and shall
have made a reasonable effort to obtain a protective order, or to cooperate with
the disclosing Party's efforts, as applicable, to obtain a protective order
limiting the extent of such disclosure and requiring that the Confidential
Information so disclosed be used only for the purposes for which such order was
issued or as required by such applicable law.

      8.5 The receiving Party agrees that its obligations under this Article 8
are necessary and reasonable to protect the disclosing Party's business
interests and that the unauthorized disclosure or use of Confidential
Information of a disclosing Party will cause irreparable harm and significant
injury, the degree of which may be difficult to ascertain. The receiving Party
further acknowledges and agrees that in the event of any actual or threatened
breach of this Article 8, the disclosing Party may have no adequate remedy at
law and, accordingly, that the disclosing Party will have the right to seek an
immediate injunction enjoining any breach or threatened breach of this Article
8, as well as the right to pursue any and all other rights and remedies
available at law or in equity for such breach or threatened breach.

      8.6 The terms and conditions of this Agreement shall be Confidential
Information of the Parties, and subject to the terms of this Article 8.

terms and conditions of this Article 8 shall survive termination of this
Agreement and continue in full force and effect for a period of **** after the
